    Intelligent Twin Input/Output Unit

    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.

    • Contains controllable isolator
    • Configurable input styles
