Motor standstill safety relays provide standstill detection for single- or three-phase motors, by monitoring the remanence voltage (back EMF) of the motor signal. These 2-channel relays offer up to four safety outputs. Models are available that monitor both standstill and speed.

Motor standstill monitoring safety relay modules provide safe standstill detection on 3-phase and single-phase motors. Access to the hazardous area of a system is only granted by the standstill monitor relay after the drive, motor, or shaft has completely stopped rotating. To detect a standstill, the remanence voltage induced by the motor windings is evaluated, providing safe standstill monitoring even if the motor/drive has already been switched off.
