ABSTRACT:
Disclosed is an AC power module for controlling the level of power to multiple electrical devices such as lights and household appliances according to control signals supplied from a processor unit. The apparatus utilizes low voltage control signals which are synchronous with the standard AC power supply to control several solid state relay which in turn regulate the AC power supplied to the devices. Each relay is optically isolated from the module. The module incorporates additional terminals through which back-up switching or control of additional relays (with different power ratings) may be provided.
The module may be constructed on a single printed circuit board (PCB) to facilitate installation and removal. According to this embodiment, the PCB has pins which matably attach to a corresponding number of L-shaped tabs provided on a standard electrical box.
