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.
Safety relay modules consist of safety relays that are controlled by built-in monitoring functions and assure a reliable opening and closing for safety applications.
UH6932 and BH5932 proximity speed monitoring and speed sensing relay modules use inputs from proximity sensors that are detecting rotating targets on the motor that needs monitoring.
Prox speed safety modules start at
UH6937 frequency monitoring safety relay modules monitor the output frequency of inverters or rotor frequency of slip-ring motors.
UH6937 series frequency monitoring safety modules are
LH5946 voltage monitoring relay modules provide safe standstill detection on 3-phase and single-phase motors by monitoring remanence voltage.
LH5946 series voltage monitoring safety modules are
