Line Voltage Interface for Automation Systems

Abstract

An integrated PCB-based solid state line voltage interface for use in automated 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 unit, and manually control the connection of the functional loads. An alternative embodiment of the present invention further includes limit switches. The compact nature of the device facilitates ease of installation, mounting of multiple units in the same space, and mounting in various specialized locations as desired.

1 . An interface for interfacing between an automated controller unit, a power source, and a reversing motor, said interface having at least one relay and at least one switch, said relay connecting said motor to said power source, and said switch facilitating manual override of said relay. 
   
   
       2 . An interface as in  claim 1 , wherein said interface comprises a printed circuit board for coupling solid state components. 
   
   
       3 . An interface as in  claim 2 , further including a second switch for controlling speed and direction of said motor. 
   
   
       4 . An interface as in  claim 3 , wherein said second switch controls power directly applied to said reversing motor.
