TSA Series Interval Solid-State Output

The TSA Series Interval Solid-State Output from the ATC Diversified Electronics division of Marsh Bellofram Corporation is a two input terminal device that connects in series with the input and load. When voltage is applied to the input terminals, the load energizes and the time delay begins. Upon completion of the delay period, the load de-energizes. Reset during or after the delay period is accomplished by removal of the input voltage.
