Distribution modules for easy connection

Schmersal safety signal distribution modules are intended for connection of safety devices to safety modules or controllers. With their help, you will significantly reduce installation costs, as they allow easy connection of safety sensors and safety switches.

Reduce installation costs

Schmersal developed two types of distribution modules – the PFB and PDM models, which differ in terms of environmental protection. All connected safety devices are individually protected by electronic fuses with automatic reset. The status of all connected devices can be easily monitored via built-in LEDs.

Both types of modules are available with individual diagnostic signals or with an SD (Serial Diagnostic) bus. Up to 4 safety sensors or safety switches with electronic output lock (OSSD) can be connected to each module, which enable serial connection. The configuration of the modules is easily set via DIP switches.
