Monitor up to three safety functions
23 April 2014
PSR-MXF multifunctional safety relays from Phoenix Contact monitor up to three safety functions in one module, making them particularly suitable for smaller machine applications. Safety-related control circuits with up to PLe or SILCL 3 can be created with the relays.
The new product range comprises four different special function modules, with three terminal block versions each. Different protection areas can be monitored in one machine, thanks to two local sensor circuits. Safety concepts are thereby simplified and machine productivity is increased.
The relay has 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.
