The eight module expansion slots are directed to four connectors in front of the controller. Connector A,B,D and E. If a module is plugged into a specific expansion slot, one half of the corresponding connector is used to interface this module. The picture below gives an overview of the connectors with their related module expansion slots.

Connector C ( in the middle) is used for controller supply and some optional CAN bus connections.

For example let’s assume an Input Module is plugged into expansion slot 5:

  • The corresponding connector is D
  • The sensor ground pins are: 24-25-26
  • The signal input pins are: 7,13,19,6,12,18,5,11,17,4

The four module expansion slots are directed to the two main connectors of the controller. Connector A and B. If a module is plugged into a specific expansion slot, one half of the corresponding connector is used to interface this module. The picture below gives an overview of the connectors with their related module expansion slots.

Connector B ( on the left in this view) is also used for controller supply, a controller enable- and reset-input and a CAN bus interface. Connector A also offers a CAN bus interface and on top of that two controller enable inputs.
