Overview

The Only 1/8 DIN Process & Temperature Meter You Will Ever Need

The PD765 Trident digital panel meter is one of the most versatile digital panel meters on the market and will satisfy a wide variety of process and temperature applications. The Trident can be field programmed to accept process voltage (0-5V, 1-5V, etc) and current (4-20 mA) inputs, 100 Ohm RTDs, and the four most common thermocouples.

One of the Trident’s most useful features is its ability to provide 24 VDC to power the transmitter’s 4-20 mA signal. It is housed in a shallow-depth, 1/8 DIN enclosure that features a NEMA 4X front panel and convenient mounting hardware. There are two power options for the Trident: 85 to 265 VAC or 12-36 VDC and the AC powered version can provide 24 VDC to power the transmitter if needed. Programming and setup can be performed with the four front panel pushbuttons, free MeterView software or using the Copy function.

Two relays and isolated 4-20 mA output options increase the utility of the Trident meter. The relays can be used for alarm or control applications. The 4-20 mA output provides an isolated retransmission of the input signal; especially useful for temperature inputs like thermocouples and RTDs.

The display height on the standard Trident meter is 0.56" (14.2 mm) and on the Trident X2 the display height is an astounding 1.2" (30.5 mm). The Trident X2 can be read easily from distances of up to 30 feet!

The intensity of the display on both versions of the Trident can be adjusted to compensate for various lighting conditions, including direct sunlight.

Both meters are available with all Trident features, although only the Trident X2 includes four external button contacts.

Advanced Display Features

Four Full Digits

The display on the Trident is four full digits which means it can display numbers up to 9999. Many digital panel meters have displays of only 3½ digits which means they can display only to 1999. In practical terms, this means the Trident can display type K thermocouples to 2300ºF and 4-20 mA signals up to 9,999.

Front Panel LEDs

The meter is supplied with two 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.

Two Display Sizes

The display height on the standard Trident meter is 0.56" (14.2 mm) and on the Trident X2 the display height is an astounding 1.2" (30.5 mm). The Trident X2 can be read easily from distances of up to 30 feet!

Trident Display Sizes

Display & Toggle Maximum / Minimum Reading

The main function of the front panel buttons during operation is to display the maximum and minimum readings reached by the process or temperature inputs. The Trident allows you to toggle between the maximum and minimum readings of the process values. To display the maximum and minimum readings since the last reset/power-up, use the Up arrow/Max button.

Process & Temperature Inputs

The Trident is factory calibrated to accept 4-20 mA, ±10 VDC, type J, K, T, or E thermocouples and 100 Ω platinum RTDs. Process inputs can be scaled with or without applying an input for virtually any engineering units. Temperature inputs can be programmed to display in degrees Fahrenheit or Celsius and the type K thermocouple can display up to 2300°F.

Current & Voltage Inputs

Setting up the meter to accept a current or voltage input could not be easier. All setup is performed with the front panel buttons and there are no switches or jumpers to deal with.

Current Overload Protection

To protect the instrument from unexpected current overload, the current input circuit contains a resettable fuse. The fuse limits the current to a safe level when it detects a fault condition, and automatically resets itself when the fault condition is removed.

Thermocouple & RTD Inputs

Setting up the Trident to accept a thermocouple or RTD input is simply a matter of setting a switch at the rear of the case and selecting the input type from the menu. The meter accepts J, K, T, or E type thermocouples as well as two, three, or four-wire 100 Ω platinum RTDs.

Thermocouple and RTD Inputs

Temperature Inputs

The Trident meter accepts J,K,T or E thermocouples and 100 Ω platinum RTDs. For the T thermocouple and RTD, the user can display temperature to 1° or 0.1° resolution and the Type K thermocouple to 2300ºF. In addition, these meters will operate down to -40°C with only mininal loss of accuracy.

Isolated Transmitter Power Supplies

24 V @ 200 mA Transmitter Power Supply

24 V @ 200 mA Transmitter Power Supply

One of the most useful features of the Trident PD765 when it is AC powered is its built-in, isolated, 24 V @ 200 mA power supply to power the transmitter. This feature saves money by eliminating an external power supply and also simplifies wiring.

24 V @ 40 mA 4-20 mA Output Power Supply

24 V @ 40 mA 4-20 mA Output Power Supply

Not only can the AC powered PD765's power the 4-20 mA input signal, but an additional power supply of 24 V @ 40 mA is available on select models to power the 4-20 mA output.

Resettable Fuse Prevents Current Overload

Another very useful aspect of the Trident is that the current input is protected against current overload by a resettable fuse. The fuse limits the current to a safe level when it detects a fault condition, and automatically resets itself when the fault condition is removed.

Isolated 4-20 mA Transmitter Output

Isolated 4-20 mA Transmitter Output

The Trident's isolated 4-20 mA output option converts the Trident into a transmitter / loop isolator with a digital display; perfect for temperature applications!

Other Uses for Transmitter Power Supplies

Trident X2 Powers Both the Heater and 4-20 mA Input Signal

The most common use for these two power supplies is for the 200 mA transmitter power supply to power the field transmitter and 40 mA power supply to power the 4-20 mA output from the meter. However, these two power supplies can be used in other ways. For instance, some level transmitters require the use of a heated lens. The Trident’s 200 mA power supply could be used to power both the heated lens and the 4-20 mA signal from the transmitter.

External Power Supply for the Loop

External Power Supply for the Loop

For applications that require an external transmitter power supply, the same Trident is used and merely wired in a different fashion as the above diagrams illustrate.

4-20 mA Output & Relays

Isolated 4-20 mA Analog Output

There are several uses for the Trident’s isolated 4-20 mA output. For temperature applications, the isolated 4-20 mA output option turns the Trident X2 meter into a temperature transmitter with a huge display! For 4-20 mA input applications the isolated 4-20 mA output turns the Trident meter into a signal isolator with the convenience of local display of the process variable. The 4-20 mA output can also be reversed scaled.

Linear 4-20 mA Analog Output

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

Convert Temperature Inputs to 4-20 mA Output with the PD765

The Trident X2, with the appropriate options, can be used as an isolated temperature transmitter with a big display by converting the thermocouple or RTD input into an isolated 4-20 mA output.

Convert Temperature Inputs to 4-20 mA Output with the PD765

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.

PD765 Provides 500 V of Isolation on the Output

The inputs and outputs of the PD765 Trident are electrically isolated to prevent ground loops and make wiring easier. All inputs, outputs and power supplies are fully isolated from one another.

PD765 Provides 500 V of Isolation on the Output

Connections

AC powered versions of the Trident can provide 40 mA at 24 VDC to power the 4-20 mA output signal or an external power supply can be used:

The meter can be set up for reverse scaling as shown to the left: the output will be 4.00 mA when the display reads 150.0 and the output will be 20.00 mA when the display reads 0.0

Sensor Break: Analog output value when TC or RTD sensor break is detected.

Relays for Alarm & Control Applications

Adding relays to the Trident 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. One such application would be pump control using the Trident’s relays in pump alternation mode. The Trident can be equipped with two 3 A Form C (SPDT) internal relays. The relays are highly user-configurable as the following screen shot from MeterView indicates:

Relay/Alarm Configuration Screen
  • Program Set and Reset Points (HI / LO Alarms)
  • Reset the Relays (Mode in MV)
  • Time Delay (On and Off)
  • Relays Auto Initialization
  • Signal Loss Relay Operation (Sensor Break)
  • User Selectable Fail-Safe Operation

Relay connections are made to a six-terminal connector labeled RELAY1 and RELAY2.

Relay Connections

Pump Controller with Dual-Pump Alternation

The PD765 can be used as a low-cost pump controller when combined with a continuous level transmitter. One of the most common pump control application is shown below: controlling and alternating two pumps. The goal is to control the level between 1000 and 6000 gallons. The main pump turns on when the level reaches 6000 gallons and pumps down to 1000 gallons and then shuts the pump off. The next cycle, the backup pump turns on at 6000 gallons and shuts off at 1000 gallons. If at any time the active pump can’t keep the level below 7000 gallons, the other pump would come on also.

Pump Alternation Step 1

Relay #1 turns the main pump on at 6000 gallons and turns it off at 1000 gallons.

Pump Alternation Step 2

With the Pump Alternation feature activated, the next time the level reaches 6000 gallons relay #2 starts the backup pump.

Pump Alternation Step 3

If the active pump is not able to keep up, and the level reaches 7000 gallons, the other relay will start the inactive pump as well.

Pump Alternation Step 4

When the level falls below 1000 gallons both pumps will turn off.

Physical Features

The PD765 Trident is designed for ease-of-use in industrial applications. It is housed in a shallow depth case and includes 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.

Wide Operating Temperature Range

Wide Operating Temperature Range

The Trident 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 Trident 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 Terminals

Removable Screw Terminal Connectors

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

Forgiving Panel Cutout

Forgiving Panel Cutout Requirement

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

Mounting Brackets

Secured-in-Place Rugged Mounting Brackets

If you’re installing the Trident 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 Trident'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.

Type 4X / NEMA 4X Front Panel

Type 4X / NEMA 4X Front Panel

Not only does the Trident’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.

Operational Features

Three Front Panel Button Operations

The main function of the front panel buttons during operation is to display the maximum and minimum readings reached by the process or temperature inputs as well as acknowledge relays.

The following buttons can perform these functions:

Front Panel Button Operations

External Button Contacts Available on Trident X2

The Trident X2 is equipped with four external button contacts that can be used to remotely operate the Trident X2’s frontpanel buttons.

For instance, these button contacts can be used to program the meter and to remotely acknowledge/reset the relays:

Light/Horn & Button Mounted to Enclosure

Light / Horn & Reset Button Mounted to Enclosure

Precision Digital offers a wide variety of NEMA 4 and NEMA 4X enclosures that can be equipped with MOD-LH Light/Horn and Button. When MOD-LH is ordered, the accompanying enclosure on the order comes with the holes pre-drilled for the Light/Horn and the Button and the user performs the mounting and wiring. Meter and enclosure are sold separately. The Light/Horn and the Button can also be ordered as separate items and the user performs all holedrilling, mounting and wiring as desired.

The light and horn can be controlled independently of each other via separate relays on the Trident X2 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 Button or front panel button on the Trident X2, and light to reset automatically when the alarm clears as the following table illustrates:

Relay #Connected toDefault Reset Mode
1Flashing Light(1)Auto reset
2HornSilence with Button at any time
  1. Light can be wired to flash or stay steady on
  2. See manual or data sheet for additional ways the relays can be programmed

Note: The Light / Horn accessory is powered from the 200 mA transmitter power supply; so when it is installed, there is less power available for the transmitter. See MOD-LH Light / Horn, Transmitter Power Supply specification in the manual or data sheet for details.

Connector Labeling

The connectors label, affixed to the meter, shows the location of all connectors available with requested configuration. It also identifies the location of the RTD/TC selector switch. The images below show all connector configurations for the PD765.

Notes:

  1. The connector in the upper left of the diagram has different configurations based on the model.
  2. The Trident PD765 does not have external button contacts like the PD765 X2, so it cannot be used with the Light/Horn accessory.
