Thermal resistance type isolator, the two-wire or three-wire system resistance signal is converted into 0/4~20mA current signal isolation or 0/1~5V voltage signal output. It is intelligent, can through the computer scope of heat resistance index number range and configuration.

This 5v to 24v signal converter should be supplied power independently. Input circuit, output circuit and power supply are each galvanically isolated.

Advantages of CZ3000 Temperature Signal Conditioner
24V DC independent/ loop power supply

Line fault detection(LFD)

Configurable by software

Integral CJC on terminals/TC input terminals
