Overview
The RTD input temperature converter with surge protection function can convert the two wire or three wire thermistor (RTD) signals into DC current signals. It can be intelligently configured, and the actual range of the thermal resistance 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.
