<p>Disclosed is an AC power module for controlling the level of power to multiple electrical devices (118, 130, 142, 156, 168, 180) such as lights and household appliances according to control signals supplied from a processor unit (182). The apparatus utilizes low voltage control signals which are synchronous with the standard AC power supply (114, 126, 138, 152, 164, 176) to control several solid state relays (116, 128, 140, 150, 162, 174) which in turn regulate the AC power supplied to these devices. Each relay (114-176) is optically isolated from the module. The module incorporates additional terminals through which backup switching or control of additional relays (with different power ratings) may be provided.</p> |
