The Speed Relay is used to monitor the speed of a rotating shaft and detect if it rises or falls below a preset safety level.
The DIN rail mounted speed relay can be used with any Rotech encoder, and with 4B’s WDA or P800 proximity sensors. A user adjustable underspeed relay contact output can sound an alarm or shutdown machinery when the shaft speed falls below the preset level.
- Use with a drive shaft encoder, wheel encoder or a proximity switch, to detect speed
- Detects under-speed
- Incremental outputs
- Can be set to personal presets as required
- With or without adjustable start-up delay
