1. General Introduction
Pepperl + Fuchs HiC2821 1-channel isolated barrier for ADV151 is used for intrinsic safety applications. It transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area.The proximity sensor or switch controls a form a normally open relay contact for the safe area load. The module output changes state when the input signal changes state. The mode of operation can be reversed with switch S1 on the side of the unit. One additional relay is available for the fault output. Line fault detection (LFD) can be selected or disabled via switch S2. During an error condition, the relay reverts to its de-energized state and the LEDs indicate the fault. A separate output bus is available. The fault conditions can be monitored via a Fault Indication Board. This module mounts on a HiC Termination Board.
