1. General Introduction
Pepperl + Fuchs HiC2831R1 1-channel isolated barrier is used for intrinsic safety applications, it transfers digital signals (NAMUR sensors or dry contacts) from a hazardous area to a safe area. Each input controls a passive transistor output with a resistive output characteristic. The outputs have three defined states: 1- Signal = 6.5 V voltage drop, 0- Signal = 33kΩ and 6.5 V voltage drop and fault > 100kΩ. This output characteristic offers line fault transparency on the signal lines. Switches allow to reverse the output mode of operation and to disable the line fault detection of the field circuit. This device mounts on a HiC Termination Board.
2. Features
