Whether for a burner control system, secure emergency shutdown, or pump controllers, Weidmüller’s safety relays guarantee safe conditions with superior and significant features. Their integration into distributed control systems (DCSs) is even better, with an input filter that makes the SIL circuit immune to the test impulse which is typically used by a DCS. The customer will also benefit from simple maintenance, since the fuses are accessible from the outside and can easily be changed. The user can see the status of the safety and the monitoring devices clearly with the status LED on the device. All devices are accredited though certification by the internationally recognized TUV-NORD group for secure process applications around the globe.
