Function & Operation
This isolated barrier is designed for intrinsic safety applications in hazardous areas. The device transfers digital signals from NAMUR sensors or dry contacts from hazardous areas to non-hazardous areas. The proximity sensor or mechanical contact controls the load for a relay contact output, with the device output changing state when the input signal changes state.
Operation mode can be reversed and line fault detection can be switched off via configuration switches. During fault conditions, the relay reverts to its de-energized state and LEDs indicate the fault according to NAMUR NE 44 standards. When operated via Power Rail, an additional collective error message is available for comprehensive system monitoring.
