Abstract
PURPOSE:To prevent false operation, by working the relays of output devices after inspecting a normal condition by means of a parity check circuit when simultaneously remote controlling a plurality of output devices of branch stations from a key station. CONSTITUTION:A parity relay 29 is added to output relays 26-28 corresponding to the output devices of a digital output portion 24 of a remote controller, an ON relay 30 for controlling said relays and an OFF relay 31, the number of the output devices driven is inspected and contacts work when inspecting results are normal. A lagged relay 32 operating by the ON of a contact of the ON relay 30 and a lagged relay 33 operating by the ON of a contact of the OFF relay 31 are mounted to a contact circuit, delayed by a time constant of RC connected in parallel with the relays, stabilized and actuated.
