The AIU Accessory Interface Unit is essential a box containing a bunch of relays that are triggered from either a DCS Remote Handheld or a iOS or Android smart device loaded with the DCS App. The AIU is connected to either the DCS TIU Track Interface Unit or WTIU WiFi Track Interface Unit and is used to operate track switches, lights, accessories and more. Essentially any model railroad component that can be controlled with a physical switch can be controlled with an AIU.

Accessories and switches are wired into the AIU in the same manner that they are connected to a physical switch. The AIU Operator's Manual details all the common accessory and switch hookup combinations. You'll have a layout wired in no time.
