PSRmultifunction safety relays
Three safety functions
in one device
The multifunctional PSR-MXF safety relay is optimized for smaller machine applications with
up to three safety functions.
Three different terminal block versions
The product range comprises four different special function modules, with three terminal
block versions each (screw connection, spring-cage connection, Push-in connection).
Higher-level sensor circuit Different protection areas can be implemented in one machine, thanks to two local sensor
circuits. Furthermore, the module has a higher-level sensor circuit, which simultaneously
switches off both protective circuits on demand and can be used for emergency stop appli-
cations, for example.
Depending on the version, all standard sensors can be connected, such as safety door lock-
ing, light grids, and magnetic switches up to PL e in accordance with EN ISO 13849-1 and
SILCL 3 in accordance with EN 62061.
