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.
24V DC independent/ loop power supply
