Multiplex transmission load controller

Abstract

Abstract PURPOSE:To turn on or off electric appliances at the same time by connecting setting methods having manual operation switches and relay contacts provided in parallel and then by connecting a subordinate console panel, which connects relay contacts to timer outputs, to a transmission line. CONSTITUTION:Terminal devices B1...B3 connected to transmission line L is provided with the signal processing circuit that consists of the oscillation part, counter, monitor input sending-back part, logical control part, control signal decision part, and address decision part. This signal processing circuit exercises a supervision over load states and on-off control. To transmission line L, main console panel A and subordinate console panel A1 are connected, and subordinate console panel A1 is provided with the signal processing circuit of the same constitution with terminal devices B1...B3; and to its input part, the encoder is connected and further, the setting method having manual operation switches and relay contacts provided in parallel are connected. In addition, those relay contacts are driven by independent relays connecting with timer outputs so as to turn on or off electric appliances through pattern switches Sb1-Sb8.
