Overview
Thermocouple input temperature converter with surge protection function can isolate and convert thermocouple (TC) DC signals into current signals. This temperature converter has built-in cold end compensation and can be intelligently configured. The actual range of the thermocouple can be set through computer software. It has the functions of wire breakage alarm and out of range alarm.
This product requires independent power supply, with isolated power supply, input, and output terminals.
