Supervisory Switch (OSY2A) System Sensor Canada

Description

System Sensor’s OSY2A is used to monitor the open position of an Outside Screw and Yoke (OS&Y) type gate valve. FM Approved and ULC Listed.
Robust Construction.
The OSY2A consists of a rugged housing, intended for indoor and outdoor use. When installed with the actuator in the vertical position, the OSY2A is NEMA 3R rated.
Application Flexibility.
The OSY2A features a user-friendly mounting bracket and adjustable shaft to permit mounting to most OS&Y valves, ranging in size from 1˝ to 12˝. Its right angle design and wide bracket span provides maximum clearance for valve components, to accommodate troublesome valves. Removing the OSY2A’s gate valve bracket allows the unit to monitor side-bracket style pressure reducing valves.
Simplified Operation.
Installation is made easier with the OSY2A’s single side conduit entrance. By providing a direct conduit pathway to the electrical source, right angle fittings are not required. Installation is further simplified by the OSY2A’s adjustable length actuator, which eliminates the need for cutting the shaft.
Reliable Performance.
The OSY2A is equipped with tamper resistant cover screws to prevent unauthorized entry. Inside, two sets of SPDT (Form C) synchronized switches are enclosed in a durable terminal block to assure reliable performance.
