Details: HiC2025ES


This isolated barrier is used for intrinsic safety applications.

The device supplies 2-wire transmitters in the hazardous area, and can also be used with current sources.

The device transfers the analog input signal to the non-hazardous area as an isolated current value.

Bi-directional communication is supported for SMART transmitters that use current modulation to transmit data and voltage modulation to receive data.

The output is selected as a current source, current sink, or voltage source via DIP switches.

A separate fault output on the bus is signaled, if the input signal is outside the range of 3 mA ... 22 mA.

This device mounts on a HiC termination board.
