I/O Expansion modules

Increasing the number of inputs and outputs

The extension of the amount of analog and digital I/Os of the MFW basic module is possible with the aid of the expansion modules. The connection is done by using the bus cable, which is in the scope of supply on one of the two CAN-bus sockets. The second socket is usable for the connection of another module or for test purposes. The power of the modules is supplied over the CAN-bus. The configuration of the modules is done simply by the DIP-switch. All expansion modules are also "hotplug" capable, i.e. the expansion can take place during operation.


As modules the following types are available:

  • Digital inputs
  • Digital outputs as relay version
  • Digital outputs as transistor version
  • Analog inputs
  • Analog outputs
  • Object protection module
