Abstract: A functional module (200) comprises one or more monitoring-and-control units (138) configured to be connected to a communication module, and a segment of computer bus (204) connecting all of the monitoring-and-control units to the communication module. Each unit allow the connection to an electrical load and is controlled by the communication module. The functional module further comprises one or more input-output modules (206) each associated with a monitoring-and-control unit, to connect the segment of computer bus to a unit and to the electrical load connected to this unit, and to allow the exchange of data between this unit and the electrical load.

Abstract: A spring connection terminal for an electrical device includes a conducting support part fixed to a main conducting part, and at least one clamping spring folded into the form of a loop and provided with a clamping window inside which a flange of the support part passes, and includes a spring stop that is folded so as to be housed inside the spring loop and which forms a guide for guiding the wire adjacent to the flange.

Abstract: A terminal connection device having an elastic cage 10 with a clamping aperture 13 for a cable C, a conducting component 20 which is provided to carry the cage. An insulating block D linked to the elastic cage carries, on the one hand an arm 31 for opening the cage and on the other hand a conducting connection arm 32, the arms being fitted in such a way that when the block is at the side of the cage, the opening arm 31 bends the loop to allow the connection arm to be introduced into the clamping aperture and to remain pressed against the conducting component.

Abstract: A protection module is provided for a contact-maker electromagnet. The resistive and capacitive elements of an RC circuit for protecting a contact-maker against parasites are disposed in an insulating module having two projecting receptacles connected together by a third flat receptacle which has passing therethrough connection conductors, two of which are extended by pins adapted for cooperating resiliently with free portions of the terminals of the coil.
