PD765 Trident Process & Temperature Digital Panel Meter
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.

Automatic Reset: Relays reset when input passes the reset point
Manual Reset: Front panel button, MeterView, Modbus registers
Time Delay: 0 to 199 seconds, on and off delays; programmable
Fail-Safe Operation: Programmable, independent for each relay. Relay coils are energized in non-alarm condition. In case of power failure; relays will go to alarm state.
Auto Initialization: When power is applied to the meter, relays will reflect the state of the input to the meter.
