Speed Relay
Rotational Speed Controller - AUE400 & SR4000 Series

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.
