OSY2 Supervisory Switch
Product Overview
- NEMA 3R rated enclosure
- User-friendly mounting bracket fits newer valve yokes
- Single side conduit entry does not require right angle fittings
- Adjustable length actuator eliminates the need for cutting the shaft
- Accommodates up to 12 AWG wire
- Three position switch monitors vandal and valve close signals
- Two SPDT contacts are enclosed in a durable terminal block for added strength
- 100% synchronization activates both alarm panel and local bell simultaneously
System Sensor’s OSY2 is used to monitor the open position of an Outside Screw and Yoke (OS&Y) type gate valve.
Robust Construction. The OSY2 consists of a rugged housing, intended for indoor and outdoor use. When installed with the actuator in the vertical position, the OSY2 is NEMA 3R rated per UL.
Application Flexibility. The OSY2 features a user-friendly mounting bracket and adjustable shaft to permit mounting to most OS&Y valves, ranging is 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 OSY2’s gate valve bracket allows the unit to monitor sidebracket style pressure reducing valves.
Simplified Operation. Installation is made easier with the OSY2’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 OSY2’s adjustable length actuator, which eliminates the need for cutting the shaft.
Reliable Performance. The OSY2 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 black to assure reliable performance.
