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 switch S1. Switch S2 allows
output II to be switched between a signal output and an error
message output. Switch S3 enables or disables 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
