Phoenix Contact PSR-MXF multifunctional safety relays

PSR-MXF multifunctional safety relays monitor up to three safety functions in one module and are therefore particularly suited to smaller machine applications. They can be used to create safety-related control circuits with up to PLe or SIL CL 3.

The range comprises four different special function modules, with three terminal block versions each. Different protection areas can be monitored in one machine, due to two local sensor circuits, allowing safety implementations to be simplified.

The relays also have a higher-level sensor circuit, which can be used for emergency stop signals, for example. All relevant sensors can be monitored, such as mechanical emergency stop signals or safety door locking, light grids, and magnetic switches. The device does not need to be configured and, for this reason, is particularly easy to maintain. The push-in fast connection technology enables tool-free installation which in turn reduces start-up times.
