Features: This isolation module need two complete independent DC12-32V power supply. Main function is input 0-10V analog voltage signal,after isolation, output 0-10V analog voltage signal. Used to isolate high voltage or strong interference voltage or current (voltage) signal then transferred to PLC or controller MCU, isolating controlling end and controlled end, to assure stability and anti-interference ability of system. It will has better performance if install this module and controller in a metal box and box is grounded. The potentiometer is used to amend corresponding relation of output voltage. Output voltage can be fine adjusted and calibrated, normally it has already been calibrated.
