Controller connectors

The CLARE 5 controller has terminal blocks on the back for connecting power, communication, inputs and outputs. Depending on the hardware configuration of the controller, 10 to 36 contacts are available. The minimum controller configuration is colored blue. In case the controller uses a LAN module (Ethernet), are terminals C1 to C4 replaced by a standard RJ-45 connector to connect to the network.

Terminal block on the source board:
