PD6400 Connections

Great For Measuring and Displaying Direct Voltage and Current

The PROVU PD6400 is a multipurpose, easy to use high voltage and current input meter ideal for measuring direct voltage and current or the output from voltage shunts and current transformers. It has one 0-300 VAC or VDC voltage input and one 0-5 AAC or ADC current input. The meter may be used with a single voltage or current input, or to measure both simultaneously. A math channel P calculates apparent power as the product of the voltage and current inputs.

The PD6400 can display voltage, current, and apparent power. The dual line display can show any two parameters simultaneously, or alternate between any parameters as well as their programmable units and tags.

A fully loaded PD6400 meter has the following: four SPDT relays and a 4-20 mA output. The PD6400 capabilities may be enhanced by adding the following external expansion modules: four SPST relays; creating an eight-relay meter, two digital I/O modules with four inputs and four outputs each, serial communication adapters for use with MeterView Pro or Modbus RTU, and a dual 4-20 mA expansion module; for a total of three 4-20 mA analog outputs.

Precision Digital offers a line of split core AC Current transformers that can be used with the PD6400 meter to measure AC current up to 1000 AAC.

Advanced Display Features

Dual-Line Makes All the Difference

The PD6400 can display voltage, current, and apparent power. The dual line display can show any two parameters simultaneously, or alternate between any parameters as well as their programmable units and tags.

The ProVu’s dual-line display makes all the difference both when programming the instrument and when using it in the field. When programming the instrument, the dual line display prompts for the needed information and also helps you keep track of where you are in the setup process. When using the instrument, the dual line display provides more information such as displaying the input in two different scales like Volts and Amps for measuring shunts and transformers. We call this the Dual-Scale feature.

Programming Assistance

The ProVu’s PD6400 dual-line display makes programming the instrument much easier because the lower line prompts for the needed information and also helps you keep track of where you are in the setup process.

Programming Assistance

The ProVu is prompting for the value for Input 2 and displaying the default value of 20.00 mA. The “2” in 20.00 is brighter than the rest of the digits indicating that it is the number that will be changed by the Up and Right arrows.

Programming Assistance

The ProVu is now prompting for what the user wants Display 2 to be; that is the value that corresponds to 20 mA. In this case Display 2 is currently set to 95.00.

Bright & Optional Super-Bright Display

The standard ProVu’s display is bright enough for most applications, including moderate sun exposure. However, for direct sunlight exposure the ProVu is available with super-bright LEDs that make it possible to read the ProVu even in direct sunlight. Both versions of the ProVu have eight levels of adjustable intensity.

Rounding Feature for Even Steadier Display

The rounding feature is used to give the user a steadier display with fluctuating signals. It causes the display to round to the nearest value according to the rounding value selected (1, 2, 5, 10, 20, 50, or 100). For example, with a rounding value of 10, and an input of 12346, the display would indicate 12350.

Display Voltage and Current Individuallyor at Same Time

The PROVU PD6400 can accept both a voltage and a current input. These can be displayed as one or the other as illustrated in the first set of screen shots below or both at the same time as illustrated by the second set of screen shots.

Alternating Input Value and Units

MeterView Pro can be used to scale the voltage and the current inputs on the ProVu PD6400 meter.

PD6400 Programming Screen

Toggling Between Reading & Units with Tag and Calculating Apparent Power

The ProVu below is programmed so the upper line toggles between the reading and units, and the lower line displays a tag. A math channel P calculates apparent power as the product of the voltage and current inputs shown in the bottom two images.

Quick & Easy Scale & Programming Methods

The ProVu can be programmed either via the front panel push buttons or free, PC-based MeterView Pro software. MeterView Pro is resident on the ProVu and is accessed by a provided USB cable, so it is by far the easiest way to program the ProVu. The ProVu can be calibrated either by applying a known signal or scaled by entering a desired value with the front panel buttons or MeterView Pro software. Most customers will use the scaling method because it is simpler and does not require a calibrated signal source. Selecting the input to be current or voltage is done with the front panel buttons or MeterView Pro software. Once programming is completed it can be locked with a password.

Free PC-Based MeterView Pro USB Programming Software & Cable

Free PC-Based MeterView Pro USB Programming Software & Cable

The ProVu comes preloaded with free MeterView Pro programming software that connects and installs directly to your PC with a standard USB cable, also provided free with each instrument. This eliminates the need to insert CDs, install drivers, or download software from the internet. When you connect your ProVu to your PC, MeterView Pro is downloaded to your PC, the software automatically selects the model you are programming, and you’re ready to start programming immediately. Further simplifying the programming process, the ProVu can be powered from the USB port, so no need to apply external power while programming your meter. In addition to programming, the software will also allow you to monitor, and datalog a ProVu using your PC. You can also generate and save programming files for later use.

4-20 mA Output & Relays

4-20 mA Analog Output

The isolated analog output can be configured to represent the process variable (PV), maximum (peak) value, minimum (valley) value, the value for any of the eight relay set points, or Modbus input. While the output is nominally 4-20 mA, the signal will accurately accommodate under- and over-ranges from 1 to 23 mA.

The 4-20 mA output can be reversed scaled such that 4 mA represents the high value and 20 mA represents the low value. For instance, a 4-20 mA output signal could be generated as the meter went from 100.0 to 0.0.

For applications where the input was linearized by the ProVu, the 4-20 mA output will represent that linearized value.

Connections

The ProVu can provide 40 mA at 24 VDC to power the 4-20 mA output signal or an external power supply can be used:

Connections

The internal 24 VDC power supply powering the analog output may be used to power other devices, if the analog output is not used. The I+ terminal is the +24 V and the R terminal is the return.

PDA1011 Dual Isolated 4-20 mA Output Module

In addition to the on-board 4-20 mA output option, the PD6400 is also available with an external module that provides two more isolated 4-20 mA outputs. This allows the user to have separate 4-20 mA outputs for current, voltage and apparent power.

PDA1011 Dual Isolated 4-20 mA Output Module

The 4-20 mA output can either be programmed using the front panel push buttons or free MeterView Pro software.

Front Panel Push Button Programming

The 4-20 mA analog output can be scaled to provide a 4-20 mA signal for any display range selected. No equipment is needed to scale the analog output; simply program the display values to the corresponding mA output signal. The Analog Output menu is used to program the 4-20 mA output based on display values.

Relays for Alarm & Control Applications

Adding relays to the ProVu meter turns it into a sophisticated alarm device as well as a powerful, yet simple, alternative to a more complicated PLC system for control applications. The ProVu can be equipped with up to four 3 A Form C (SPDT) internal relays and an additional four more 3 A Form A (SPST) external relays. Relays are highly user-configurable as the following screen shot from MeterView Pro indicates:

Relays for Alarm & Control Applications
Setting Set and Reset Points (HI / LO Alarms)

All relays are independent of each other and may be programmed as high or low alarms with user desired set and reset points. Setting a set point above a reset point results in a high alarm and setting a set point below a reset point results in a low alarm. Alarms have 0 – 100% deadband and set and reset points may be set anywhere in the range of the meter.

Resetting the Relays (Action in MV Pro)

All relays are independent of each other and may be programmed to reset (Action in MV Pro) in the following ways:

  • Automatic: Alarm will reset automatically once the alarm condition has cleared.
  • Automatic/Manual: Alarm will reset automatically once the alarm condition has cleared but can also be reset using the F3 front panel button* at any time.
  • Latching: Alarm must be reset manually and can be done so at any time. Press the F3 front panel button* at any time to clear the alarm.
  • Latching with Reset after Cleared: Alarm must be reset manually and can only be done so after the alarm condition has cleared. Press the F3 front panel button* after the alarm condition has cleared to reset the alarm.

* Or by connecting an external switch to F4 terminal or with an optional digital input.

Time Delay (On and Off)

In many applications it is desirable to wait before turning off or on a relay – such as waiting for a process to settle before taking action. Each relay on the ProVu can be programmed with independent on and off time delays of 0 to 999.9 seconds to achieve this.

Relays Auto Initialization

When power is applied to the meter, the front panel LEDs and alarm relays will reflect the state of the input to the meter.

Signal Loss or Loop Break Relay Operation

When the meter detects a break in the 4-20 mA loop, the relay will go to one of the following selected actions:

  1. Turn On (Go to alarm condition)
  2. Turn Off (Go to non-alarm condition)
  3. Ignore (Processed as a low signal condition)
User Selectable Fail-Safe Operation

All relays are independent of each other and may be programmed for user selectable fail-safe operation. With the fail-safe feature activated, the relays will transfer to the alarm state on power loss to the meter.

Front Panel LEDs

The meter is supplied with four alarm points that include front panel LEDs to indicate alarm conditions. This standard feature is particularly useful for alarm applications that require visual-only indication.

Manual Output Control

Take control of any output with this feature. All relays can be forced ON or OFF, and the 4-20 mA output signal can be set to any value within its range. When the relays and 4-20 mA output are controlled manually, an LED labeled “M” is turned on and the associated Alarm LEDs (1-8) flash every 10 seconds indicating that the meter is in manual control mode.

Manual Output Control
Sampling Function (PV Triggered Timed Relay)

The sampling function allows the operator to set a relay as a “sampling” relay. When the PV reaches that set point, it will close that relay’s contacts for a preset period of time (0.1 to 5999.9 seconds).

Interlock Relay(s)

This function allows a process to use one or more very low voltage input signals or simple switch contacts to control the state of one or more internal “interlock” relays. A violation (i.e. loss of input, open switch, or open circuit) forces one or more N/O interlock relay contacts to open. One input can be used in series with a number of interlock switches, or up to eight inputs can be required to force-on one (or more) internal interlock relays. Requires PDA1044 Digital I/O module or use of on-board digital input F4. Please see ProVu Series Safety Interlock Feature whitepaper on our website for more information.

Interlock Relay(s)
Switching Inductive Loads

The use of suppressors (snubbers) is strongly recommended when switching inductive loads to prevent disrupting the microprocessor’s operation. The suppressors also prolong the life of the relay contacts. Precision Digital offers the PDX6901:

Application Examples

The PD6400 ProVu can be used to display application data for voltage, current, both, or apparent power. Each Channel, Voltage, or Current, can be scaled independently. The following examples show just a few of the PD6400's application capabilities using generators and transformers. Each example is followed by a wiring diagram that shows proper switch position for the meter.

PDA6405 Split Core AC Current Transformers

PDA6405 Split Core AC Current Transformer

Precision Digital offers a line of split core AC current transformers that convert the high AC current flowing through a cable or wire to a 0-5 AAC output that can be displayed on a PD6400. The PDA6420 works with a PD6400 because it puts out a 4-20 mA signal. They are available in ranges of 100, 200, 400, 600, and 1000 AAC. These nonintrusive devices feature split core convenience for easy installation and are a cost effective solution for monitoring load or proof of operation. The PDA6420 current transformers are ideal for monitoring current loads on pumps, driving fans and blowers, and sensing the status of heating coils and lighting.

Digital Communications

Modbus® RTU Serial Communications

With the purchase of a serial communication adapter, PROVU meters can communicate with any Modbus Master device using the ever-popular Modbus communications protocol that is included in every PROVU. In addition to the typical Modbus capabilities of reading PVs and writing set points, below are some examples of other things that can be done with the meter’s Modbus communications:

  • Send a 6-character message to lower display upon an event

Field Expansion Modules

Add functionality to the PD6400 n the field with easy-to install external expansion modules. External expansion modules are available for RS-232 or RS-485 communications, digital I/O, 4 relays and dual 4-20 mA outputs. The menu items for these modules do not appear until the module is connected, simplifying the basic menu. Relay and digital I/O modules are shown below with optional DIN rail mounting kit, P/N PDA1002.

PDA1044 I/O Expansion Module

Four digital inputs and four digital outputs are available per expansion module. The PROVU meter will accept two of these modules. External digital inputs can function similarly to the front panel function keys or on-board digital input F4. They can be configured to trigger certain events (i.e. acknowledge/ reset alarms) or mimic front panel keys. The I/O module can be used to configure the PROVU remotely, in essence giving the user control of the four front panel push buttons.

Digital outputs can be used to remotely monitor PROVU’s alarm relay output states, or the states of a variety of actions and functions executed by the meter.

PDA1044 I/O Expansion Module

PDA1004 Relay Expansion Module

An external module containing four 3 A Form A (SPST) relays can be added to the PROVU at anytime. Removable screw terminal blocks accept 12 to 22 AWG wire.

PDA1004 Relay Expansion Module

PDA1011 Dual Isolated 4-20 mA Output Module

In addition to the on-board 4-20 mA output option, the PD6400 is also available with an external module that provides two more isolated 4-20 mA outputs. This allows the user to have separate 4-20 mA outputs for current, voltage and apparent power. relays can be added to the PROVU at anytime. Removable screw terminal blocks accept 12 to 22 AWG wire.

Physical Features

The ProVu is designed for ease-of-use in industrial applications. Considerations include a NEMA 4X front panel, wide operating temperature range, removable screw terminal connectors, snap in place mounting brackets, forgiving panel cutout requirement, and UL Listing for electrical safety. All of these features are backed by a 3-year warranty.

Type 4X / NEMA 4X Front Panel

Type 4X / NEMA 4X Front Panel

Not only does the ProVu’s front panel UL Type 4X approval indicate it is waterproof, but it also indicates it is rugged. Part of the UL Type 4X test is to drop a 2 inch solid stainless steel ball from 8 feet on top of the meter’s faceplate.

Wide Operating Temperature Range

The ProVu can operate from -40 to 65°C (-40 to 150°F) meaning it can be installed in a wide variety of indoor and outdoor industrial applications. And over this range, the ProVu will drift no more than 0.005% of calibrated span/°C max from 0 to 65°C ambient and 0.01% of calibrated span/°C max from -40 to 0°C ambient.

Removable Screw Terminal Connectors

Industrial applications require screw terminal connections for easy field wiring and the ProVu goes one step further in convenience by making them removable also.

Removable Screw Terminal Connectors

Secured-in-Place Rugged Mounting Brackets

If you’re installing the ProVu outdoors in the hot or cold weather, the last thing you want to do is fumble around with mounting brackets that don’t stay in place. The ProVu’s mounting brackets can be easily secured into place and then screwed down to the panel. These brackets are rugged so they can be tightened to the panel to provide a solid NEMA 4X seal.

Secured-in-Place Rugged Mounting Brackets

Forgiving Panel Cutout Requirement

The ProVu’s bezel has been oversized to allow for not perfectly executed panel cutouts where NEMA 4X seal is not required.

Operational Features

Function Keys, F4 Terminal, Digital Inputs

There are three ways the user can interact with the ProVu to perform a variety of useful functions:

1. Three Front Panel Function Buttons

The default settings for the function keys are:

Three Front Panel Function Buttons
2. F4 On-Board Digital Input

The PD6400 includes a digital input as standard. This digital input can operate with the interlock relays feature, force relays on from a signal from a PLC or relay on other equipment, and much more. This is ideal for installations where the meter is inaccessible behind a cover, or where an additional function key is needed for customized operation.

F4 On-Board Digital Input

The F4 terminal is particularly useful for wiring up a remote switch to reset the relays as shown here:

Reset Switch
3. Optional 4 Digital Input/Output Module PDA1044
Optional 4 Digital Input/Output Module PDA1044

With these three methods, the ProVu can be programmed to trigger certain events (i.e acknowledge relays, reset max and/or min, disable/enable output relays, or hold current relay states), provide direct menu access points and more.

Remote Operation Using PDA2364-MRUE Control Station

The PD6400's four internal programming and operations buttons can be remotely controlled by using the PDA2364-MRUE 4-button control station accessory as shown in the diagram below.

Remote Operation Using PDA2364-MRUE Control Station

Remote Operation of Front Panel Buttons

The user can operate the front panel buttons from a remote location by using digital inputs programmed in the following manner:

Remote Operation of Front Panel ButtonsProVu Function Keys

Max / Min Display

Max/Min (or Peak/Valley) is standard on the ProVu PD6400. Either display can be configured to show either maximum or minimum excursion since last reset. The displays can also be configured to toggle between Max and Min values. Both values can be simply reset from the front panel.

MeterView Pro Monitoring & Datalogging Software

Not only does free MeterView Pro software greatly simplify setup and programming of the ProVu, it can also be used to monitor and datalog your process.

Relay Control

Relays can be controlled from MeterView Pro for testing purposes. This is commonly done to determine whether the relays are functioning properly. In the Setup window, under Relay and Digital Out Test you have the option of selecting the relays you want in an ON state or OFF state and also whether you want to leave the relays in manual control or to return them to automatic operation.

Light / Horn & Reset Button Mounted to Enclosure

Overview

Precision Digital offers a wide variety of NEMA 4 and NEMA 4X enclosures that can be equipped with MOD-LH Light / Horn and Reset Button. When MOD-LH is ordered, the accompanying enclosure on the order comes with the holes pre-drilled for the Light / Horn and the Reset Button and the user performs the mounting and wiring. Meter and enclosure are sold separately. The Light / Horn and the Reset Button can also be ordered as separate items and the user performs all hole-drilling, mounting and wiring as desired. The light and horn can be controlled independently of each other via separate relays on the ProVu meter; and since the meter's relays can be reset in a variety of ways, there are several ways the Light / Horn option can operate. For instance, the horn can be programmed to silence at any time via the Reset Button or F3 front panel button on the ProVu, and light to reset automatically when the alarm clears as the following table illustrates:

Relay #Connected toTypical reset method
