Product details
Intrinsic safety & signal conditioning
Switch amplifier - 12.5mm
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 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.
