Abstract (en)
[origin: EP0444636A2] In a system for remotely controlling a plurality of lighting equipments wherein remote-controlled relays (61 to 64) are driven by a control terminal 3B connected to a main controller via a transmission line (2) and lighting equipments (5) connected to the remote-controlled relays (61 to 64) via a power source line are turned on/off by an opening/closing operation of a relay contact (R), a remote-controlled transformer (7), which supplies driving power source to the control terminal (3B) and the remote-controlled relays, is arranged in one row in a distribution board, and the control terminal (3B) is arranged between the remote-controlled relays (61 to 64) and the remote-controlled transformer (7). Then, a power signal output from the remote-controlled transformer (7) is supplied to the remote-controlled relays (61 to 64) via the control terminal (3B), thereby preventing a signal line, which transmits a control signal to the remote-controlled relays (61 to 64) from the control terminal (3B), from crossing a signal line, which is input from the remote-controlled transformer (7). <IMAGE>
