Introduction Data sheets Operating Instructions Certificates

The Digital Input Module is used for the connection and supply of up to 16 volt-free contacts or proximity switches acc. to EN 60947-5-6 (NAMUR). All inputs are intrinsically safe, short-circuit proof and individually monitored for open-circuit and short-circuit.

Channels 14 and 15 can also be used for frequency measurement or as pulse counters up to 20 kHz.

The interface of the Digital Input Module with the internal data bus of the BusRail is designed with redundancy.
