IO Expander Board

The IO Expander Board is a DIN-rail mounted output board for sending alarms or trigger outputs for providing traffic information to VMS or Traffic Controllers, or for remotely activating or deactivating outputs for controlling any external equipment.

The board also has inputs for receiving alarms or inputs from other equipment.

The IO Expander has two battery voltage meters to supervise batteries for third party equipment at a road-side installation.
