The Intelligent Twin Input/Output Unit is available in the new faceplate style enclosure. This can be mounted with the supplied backbox for surface mounting or flush mounted using a UK double gang, flush mounting back-box of minimum depth 30mm.
The Intelligent Twin Input/Output Unit provides the function of two Input/Output Units within one enclosure. The two units are electrically independent of each other. There is a DIL switch on each unit to set the address.
Both input/output units in the enclosure provide supervision of one or more normally open volt free contacts connected to a single pair of cables and a set of changeover relay output contacts.
