Asco Relay Panel - 120 VAC (Input), 80 VDC (Output)

Features: If the control voltage is lost completely, or reduces to approximately 50% of normal value, the relay de-energizes the normally closed valve to shut off gas flow. The valve will not open at restoration of voltage until an authorized person operates the key switch on the control station. This eliminates the danger of gas unknowingly escaping. The gas may also be shut off by depressing the normally closed push-button switch located on the control station. Utilization of DC control provided by the relay panel eliminates annoying AC hum. Clearly marked terminals and installation drawings are located on inside of door. Shallow-depth NEMA Type 1 flush-mounted enclosure permits installation directly into the wall for convenience and elimination of obstructions in corridors or high traffic areas. ASCO dust-tight industrial relay and solid-state rectifier are designed to provide long life.
