Leuze MSI-s/R, MSI-sx/Rx Configurable Safety Relays

          Leuze MSI-s/R, MSI-sx/Rx Configurable Safety Relays

When increased functionality is required in automated production processes, the configurable MSI-s and MSI-sx Safety Relays are preferred over simple Safety Relays.

These configurable MSI Safety Relays type 4, in accordance with IEC/EN 61496-1, can be flexibly connected as the link between opto-electronic protective devices and the machine control unit. In addition to standard functions such as start/restart interlock and contactor monitoring they also feature a type 2 test monitoring. The MSI-sx ("extended") model also enables the connection of E-STOP control devices or Safety Switches.

Furthermore switching cycles can also be counted and automatically signal when a pre-selected value is reached. Preventive maintenance is possible with this warning in good time before a device failure, which in turn provides additional reliability with regard to system availability.
