1) Brief Introcucion

    LU-G22 isolators/power suppliers (2 input,2 output) (type S) are used to each kind of signal input circuits such as the 2-wire transmitter input,voltage/current input,THC input,RTD input and slide-wire resistance input.The isolators/power suppliers would transform the above signals to isolated standard process signals and then output to control systems or intelligent instruments.

2) Technical Parameters:
