Function

This isolated barrier is used for intrinsic safety applications.

The device transfers digital signals from NAMUR sensors or dry contacts from the hazardous area to the non-hazardous area.

The proximity sensor or the mechanical contact controls the control side load for a relay contact output. The device output changes the state when the input signal changes the state.

Via switches the mode of operation can be reversed and the line fault detection can be switched off.

During a fault condition, the relay reverts to its de-energized state and the LEDs indicate the fault according to NAMUR NE 44.

If the device is operated via Power Rail, additionally a collective error message is available.
