Signal Isolator

CZ3079 2 Channels Signal Isolator

CZ3079 Signal Isolator range signal conditioners are electrical devices, which are connected between the industrial field instrument and the control room. They effectively solve the field interference of industrial automation control systems and ensure stable and reliable operation of the system through reliable galvanic isolation among the power supply, input, and output. The product model is rich, and basically covers various signal

isolation, conversion, distribution and other functional requirements in the automatic control system.
