The 2368 Series Electric Pneumatic Relays are 3-way, 2-position, electrically activated air valves for use in pneumatic control systems where the application requires a variety of switching, diverting, or interlocking functions, actuated by an electrical circuit. The 2368-500, 501, 502, and 503 have one SPDT pneumatic circuit that they switch, while the 2368-520, 521, 522, and 523 are designed with DPDT pneumatic switching (two independent SPDT pneumatic circuits). On models 2368-500, 501, 502, and 503, when the coil is de-energized, ports "C" to "NC" are connected with port "NC" blocked. With the coil energized, ports "C" to "NC" are connected with port "NO" blocked.
On models 2368-520, 521, 522 and 523, when the coil is de-energized, ports "C" to "NO" and "C2" to "NO2" are connected with ports "NC" and "NC2" blocked. With the coil energized, ports "C" to "NC" and "C2" to NC2" are connected with ports "NO" and "NO2" blocked.
This device is to be used on clean, dry, oil-free control air only and will operate properly when mounted in any position. The inherent reliability of this device is enhanced and prolonged through regular inspection and preventive maintenance by a qualified control expert. If failure is due to a problem other than the coil, the device should be replaced by a new unit.
