PCT No. PCT/EP93/01920 Sec. 371 Date Jan. 19, 1995 Sec. 102(e) Date Jan. 19, 1995 PCT Filed Jul. 20, 1993 PCT Pub. No. WO94/02919 PCT Pub. Date Feb. 3, 1994An automatic control system for a series circuit, in particular for airport signaling lights, physically separated from the work circuit feeding the lights and galvanically separated from the latter, includes a computer; several Main Stations each containing several Main Modules, each controlling several Remote Modules which check and act on a single airport light, each of said Main and Remote Modules having firmware boards; a full duplex transmission network linking the computer with the Main Stations; each Remote Module has externally two pairs of electric terminals of which one pair is connected to the secondary of an insulating transformer making part of the work circuit and the other pair is connected to a light or a group of lights being controlled, the two pairs of electric terminals being connected to each other by electrical leads, wherein connected in series to one of the electrical leads is a coil which is magnetically coupled to a Hall sensor of the Remote Module; and further including an electronic device with controlled conduction having two conducting terminals and a control terminal, each conducting terminal connected with one of the electric leads while the control terminal is connected to circuitry which connects the electronic device magnetically to internal circuitry of the Remote Module itself. |
