NPWD-C1AD.TC

This temperature transmitter converts the thermocouple signals to 4~20mA signals, one relay alarm output. It has external cold junction compensation terminals. It needs an independent power supply. The input, output, and power supply are galvanically isolated from each other. The self-test function is also available on this device. Calibrate the apparatus or modify parameters by using a handheld programmer.
