WHAT IS IT?
The Model SRC is a direct drive control that indicates when rotating equipment has ceased to turn. The output contacts of the Model SRC can control up to two separate circuits – one for machinery shutdown and one for an alarm.
WHY IS IT NECESSARY?
The Model SRC provides a means of protection to prevent compound damage from inoperative or failed equipment due to a lack of rotation.
Technical Specifications
- The housing is cast aluminum, with optional epoxy or polyester powder coating available (for additional corrosion resistance).
- The unit can be connected to rotating equipment by means of a stub shaft and flexible coupling.
- The unit is mounted on the conveyor by drilling (4) 5/16" diameter holes.
- General purpose (weather-proof) units and explosion-proof units have (2) 3/4" NPT conduit openings.
- The standard unit has 120 VAC power input (120 VAC transformer). Optional 240 VAC power input (240 VAC transformer) and 24V AC/DC (transformer-less) available upon request.
- The unit has a dry, unpowered DP/DT relay rated for 3A @ 120 VAC, 240 VAC, and 480 VAC.
- The unit is bi-directional – it will detect motion or loss of motion in either direction.
- The standard unit has a 12-segment brass encoder disk. A special 50-segment brass encoder disk can be supplied for low RPM applications (5 RPM or less). Specify "-50".
- The operating temperature class is T6 (85°C [185°F]).
- The maximum ambient temperature is 55°C [131°F].
- The maximum operating speed is 1000 RPM.
- The general purpose units are rated NEMA Type 4/4X weather-proof and corrosion-resistant, and explosion-proof units are rated NEMA Type 7/9 for vapor explosion-proof and dust ignition-proof (Class I, Div 1, Groups C & D; Class II, Div 1, Groups F & G).
- The general purpose controls are IP65 compliant.
- Most models are cULus Certified.
