Proven safety thanks to force-guided contacts

Force-guided contacts  

Force-guided contacts

The N/O and N/C contacts of an elementary relay are connected to one another mechanically through forced guidance. This prevents N/O and N/C contacts from closing at the same time. In conjunction with a suitable circuit, failure to open can be reliably detected. This is the most reliable way to ensure maximum safety for both person and machine.

In order to provide a high level of safety, our PSRmini, PSRclassic, and PSRmodular products are equipped with force-guided contacts.

System cabling with the Termination Carrier

Termination Carriers and PSRmini: unique packing density in the control cabinet

The Termination Carriers are designed to accommodate the PSRmini and PSRclassic. With the module carriers, you can reduce your wiring outlay and speed up installation. 

Thanks to a consistent concept and specific system technology, you avoid wiring errors with the Termination Carriers, and therefore eliminate the cause of expensive and time-consuming troubleshooting.

We'll be happy to adapt the Termination Carriers to suit your specific requirements.
