40701 – Benefit from our experience in safety technology. If you only require a few safety functions in your machine, our safety devices are the ideal solution. Functional safety based on the modular system principle means that you can assemble your safety system as required. In combination with the master safety relay and the DIN rail connector, this provides a flexible solution for the individual integration of functional safety. Whether in the process industry or machine building: reliable signal coupling must be ensured in the event of an emergency. Phoenix Contact offers safety relays with forcibly guided contacts for this. Emergency stop, light grid or safety door – PSR safety relays from Phoenix Contact can be used to implement all safety functions for applications with one function, one device.
