The Trident PD765 digital panel meter is one of the most versatile meters on the market and will satisfy a wide variety of process and temperature applications. Housed in an 1/8 DIN enclosure with a NEMA 4X front, the meter can be field programmed to accept process voltage (0-5 V, 1-5 V, etc.) and current (4-20 mA) inputs, 100 Ohm RTDs, and the four most common thermocouples. 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 intensity of the display can be adjusted to compensate for various lighting conditions, including direct sunlight. Programming and setup can be performed with the four front panel pushbuttons, free MeterView software, or using the copy function. Options for the PD765 include 2 relays, a 4-20 mA output, 24 V transmitter power supply, and Modbus® serial communications.
Go with the Helios PD2-6000 when you need a large display meter to display the 4-20 ma output from any transmitter you might have. The PD2-6000 can display that output in six full digits and will also provide the 24 VDC to power the transmitter. The PD2-6000's NEMA 4X enclosure, super bright, 1.8" (46 mm) high LEDs, and wide operating temperature range make it perfect for outdoor applications. The PD2-6000 can also be equipped with a 4-20 mA output as well as four relays that can be used for alarming or control applications, including pump alternation control.
The PDA8068 USB serial adapter is used to connect the PD6830, PD6830X, and PD6730 directly to a computer via USB. This module connects the internal electronics module directly to a computer, and only allows for programming of the units. No live monitoring is possible with this module. This is ideal for quickly connecting to MeterView EX or ScanView EX for programming. USB and meter to adapter cables are included.
The Precision Digital PDW30 provides a simple, straightforward way to get an analog, discrete (digital) or Modbus signal from where you have it to where you need it – without having to run wires! It’s a point-to-point wireless bridge that is virtually plug and play right out of the box.
The PDW30 consists of a primary and a secondary unit and communication between the two is by-directional. That means you can send 4-20 mA, discrete and Modbus signals from the primary unit to the secondary unit and also send completely different 4-20 mA, discrete and Modbus signals from the secondary unit to the primary unit. For instance, the primary unit could send a 4-20 mA signal to the secondary unit corresponding to the level in a tank and the secondary unit could send a 4-20 mA signal to the primary unit to control a valve.
Primary and secondary units are also equipped with four digital I/O that can each be independently programmed as an input or an output. A Loss of Signal warning is also available by connecting devices to the G and LS screw terminals.
To indicate alarm situations, both units can be equipped with an optional, field installable, two relay module. These relays are rated Form A (SPST) 5A.
The specified range between the primary and secondary unit is 1 mile line-of-sight outdoor and 500 feet indoor and repeaters are available to extend the range. A low-cost wireless survey tool, Model PDA10, is available to test the signal strength of your application before you buy. And if the PDW30 system does not work in your application, you can return it for full credit!
