Soteria Input Output Unit

Soteria Input Output Unit

The Soteria Input Output Unit provides supervision of one or more normally open contacts connected to a single pair of cables and a set of changeover relay output contacts.

The Soteria Input Output Unit is available in the new faceplate style enclosure. This can be surface mounted with the supplied back-box or flush mounted using a UK double gang, flush mounting back-box of a minimum 30mm depth.
