10 Channel Input Module.

The 10 channel Input Module is a GOcontroll Moduline compatible expansion card to add 10 general purpose input ports to your modular controller. The inputs are protected and configurable individually for a wide range of applications. The configuration can easily be set by the user in Node-RED.

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.

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.
