The Marine DIN-Rail Input/Output unit provides a voltage-free, single, pole, change-over relay output, a single monitored switch input, and an unmonitored, non-polarised opto-coupled input.
The Marine DIN-Rail Input/Output unit supervises one or more normaly-open switches connected to a single pair of cables. It is set to return an analogue value of 4 in the event of an open or short-circuit fault and 16 during normal operation. The status of the inputs is reported by means of two input bits.
The changeover contact is operated by a software command from the panel.
