The TÜV-certified, safe PSR-MM35 over-speed safety relay monitors speeds without additional sensors. Based on the rotary field measurement of the drive, the integrated safety functions are reliably implemented up to SIL 3 or PLe.
Integrated safety functions:
- STO (Safe Torque Off)
- SLS (Safely Limited Speed)
- SSM (Safe Speed Monitor)
- SSR (Safe Speed Range)
Sensor-free technology eliminates the costs for additional sensors for speed monitoring. Save up to 50% of your procurement costs.
External sensors are susceptible to interference from environmental influences such as shock, vibration, and EMC. The rotary field measurement of the drive is independent of disruptive factors, allowing maximum availability of the system to be achieved.
Without additional sensors, there is no need for further assembly and adjustment work. The intuitive PSRmotion configuration software further reduces the installation and commissioning time of the over-speed safety relay.
