The 2373-501 Selector Relay is a device designed for use in pneumatic control systems where the application requires the comparison, selection, and transmission of the highest and/or the lowest of up to six pneumatic input signals. All input ports are "dead-end" and no signal air passes through the relay to the output ports.

The 2373-501 has been designed for pilot duty; for direct actuator operation, use with the 2372-501 Booster Relay, 2341 Series Receiver-Controllers, or other volume amplifying devices. If valves or damper actuators are equipped with positive positioning relays, the output of the 2373-501 will normally be sufficient.
