Suited for an expanse of process and temperature applications, Precision Digital is offering their Trident PD765-6R 85-265 VAC, 90-265 VDC Process and Temperature Digital Panel Meter. The PD765-6R is able to be field programmed to accept process voltage, like 0-5V, 1-5V, etc., 4-20 mA current inputs, 100 Ohm RTDs, and the 4 most common thermocouples. Users can setup and program the meter via the 4 front panel pushbuttons, free MeterView software or by utilizing the copy function.
The meter is crafted in a 1/8 DIN enclosure with a NEMA 4X front and a 0.56” (14.2 mm) display height. More still, the display’s intensity can be modified to adjust to different lighting conditions, like direct sunlight. For even more user versatility the PD765-6R offers the options of 2 relays, a 4-20 mA output, 24 V transmitter power supply and Modbus serial communications.
