Safety Speed/Standstill Relays (Prox Speed, Frequency & Voltage)

Safety relay modules provide a high level of fail-safe operation for critical processes and protection. These speed safety relays provide overspeed, underspeed and/or standstill detection for single- or three-phase motors, by monitoring either external proximity sensors, or the frequency or remanence voltage (back EMF) of the motor.
