and to not exceed 5 km in length. For connections that are particularly critical in terms of electro-
magnetic pollution, it is recommended to use BFO adaptor modules with fibre optic connection.
When devices without committed pilot wire circuits must be embedded (devices other than Pro_N),
or in the event that further I/O circuits are need, output relays and binary inputs can be customized
to work in the logic selectivity system together with the committed pilot wire circuits.
