Analog Signal Isolator
Analog signal isolator provides isolation for single channel input DC current or voltage signal, and converts it into two isolated analog outputs. It can work with a transducer to generate a signal channel for programming device or other signal channels connecting to field signal indicator. Due to its single channel of input signal, the analog signal isolator enables the voltage drop to be constant, up to 3.5V, without being affected by loads. The isolation voltage of optocoupler is up to 2kV.
