The Switch Module card is used to simulate relays or contact sensors via switches which are individually controlled from the user interface.

The switches are grouped in three different types: discrete (30), flexible (5), rotary (1); each type having specific voltage level configuration settings as described in the Switches description section. 

The board is protected for over-current conditions.

The board  also supports the following features, which are common to all OP6200 I/O boards :
