Overview
The ISSC 1214-1JB motion detector is an industrial-grade underspeed detection relay manufactured by ISSC/Kanson Electronics. This device detects zero-speed, underspeed, or overspeed conditions in rotating equipment such as pumps, conveyors, blower fans, and other machinery that requires continuous speed monitoring. Base-mount design with screw terminals makes it suitable for panel installation in facility maintenance, safety, and alarm system applications.
Key Features
- Underspeed motion detection for equipment health monitoring
- Adjustable timing range from 0.06 to 0.50 seconds
- 10 amp output relay rating at 115V
- NO/NC (normally open/normally closed) contact configuration
- Base-mount design with screw terminal connections
- Mechanical and electrical relay contacts for control flexibility
