Intrinsically Safe Barrier / Repeater Power Supply / Signal Converter

The ZS-30/1Ex power supply and isolator is designed to supply power to transmitters with a 4…20 mA signal in a two-wire transmission and either repeat or convert that signal through galvanic separation into one of the standard signals used in automatic control: 4…20mA, 0…20mA; 0…5mA; 0…10V, 0…5V, 1…5V, 2…10V.

Input, Output and Supply circuits are galvanic separated from one another for maximum protection, resistance to interference and performance.
