Features
• 1-channel signal conditioner
• 24 V DC supply (Power Rail)
• Dry contact or NAMUR inputs
• Relay contact output
• Fault relay contact output
• Line fault detection (LFD)
• Housing width 12.5 mm
• Up to SIL2 acc. to IEC 61508
Function
This signal conditioner transfers digital signals (NAMUR
sensors/mechanical contacts) from the field to the control
system.
The proximity sensor or switch controls a form A normally
open relay contact for the load. The normal output state is
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
switching states in space-critical applications.
