The Soteria 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.
