Abstract
Abstract System for selectively energizing and deenergizing a plurality of signalling and control electromagnetic relays arranged in several groups in the junctors of a switching network under the control of at least two control computers. The relays to be actuated have first and second half-windings interconnected at a common point which is connected to a grounded holding contact of each relay and the terminals of the two half-windings are first connected to a current source pole and second to a selector switch through a crosspoint of an address matrix. This selector switch connects the terminal of the second half-winding to the ground for an activation of the relay and to the current source pole for a release of the relay. An address signal and an order signal are forwarded by one of the control computers respectively to an address register associated with the address matrix and to an order register associated with the selector switch. According to the address signal, a crosspoint of the matrix is actuated and, according to the order signal, the selector switch connects the terminal of the second half-winding of the relay for activation or release. Means are provided for deriving from the establishment or release of the feed current in the relay a check signal and for actuating a fault circuit when the time interval between the order signal and the check signal reaches a predetermined value.
