Abstract: An integrated printed circuit board-based solid state line voltage interface for use in automation control system applications. Relays connect various functional loads to the line level source in response to input from a controller unit. Switches enable a user to override the controller and manually control the connection of the functional loads. An alternative embodiment further includes limit switches and time delays. The compact nature of the device facilitates ease of installation, mounting of multiple units in less space, and mounting in various specialized location as desired.
