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.

Each proximity sensor or switch controls an active transistor output for the safe area load. The desired arrangement between the input channel and output channel can be configured. The assignment of multiple outputs to one input signal is possible (signal duplication). The assignment of multiple inputs to one output is also possible. The mode of operation and the line fault detection can be determined for each individual channel. This allows a desired mix of sensors and mechanical contacts with or without LB/SC.

The device is easily configured by the use of configuration software.

During an error condition, the transistor reverts to its de-energized state and the LEDs indicate the fault according to NAMUR NE44.
