1. General Introduction
Pepperl + Fuchs HiC2873 1-channel isolated barrier for SDV541 is used for intrinsic safety applications, It supplies power to solenoids, LEDs, and
audible alarms, located in a hazardous area.It is controlled with a loop-powered control signal, switch contact, transistor, or logic signal. At full load, 12 V at 40mA (with 55mA current limit) is available for the hazardous area application. Line fault detection of the field circuit is indicated by a red LED and an output on the fault bus. This device mounts on a HiC Termination Board.
2. Features
