Function

This isolated barrier 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 normal output

state can be reversed using switches S1 and S2. Switch S3 is

used to enable or disable line fault detection of the field circuit.

During an error condition, relays revert to their de-energized

state and LEDs indicate the fault according to NAMUR NE44.

A unique collective error messaging feature is available when

used with the Power Rail system.

Due to its compact housing design and low heat dissipation,

this device is useful for detecting positions, end stops, and

switching states in space-critical applications.
