Embodiment Construction

[0040] First refer to image 3 , image 3 A first exemplary embodiment of the electromagnetic contactor according to the present invention is shown.

[0041] This embodiment corresponds to an arrangement of electromagnetic contactors with a single electromagnetic field generator associated with an adjustable core P mechanically connected to the three switches C1, C2 and C3 of the power line .

[0042] It can be seen that the electromagnetic field generator herein consists of a coil L associated with an adjustable core P.

[0043] The electromagnetic contactor includes a central unit UC, an input circuit 1DSI and an output circuit 2DSO. The central unit UC is composed of a microcontroller or another programmable logic element. The input circuit 1DSI receives the control signal CMD, and the output circuit 2DSO includes an analog auxiliary contact. The open collector stage. The output circuit provides two outputs DSO_OL1 and DSO_OL2 corresponding to the normally open auxiliar...

Abstract

The electromagnetic contactor comprises: a group of controlled switches (C1, C2, C3); at least one electromagnetic field generator (L; L1, L2), such as a coil, which is connected with an adjustable core for controlling the state of the controlled switches body (P); and a unit (UC) that controls the power supply of the electromagnetic field generator. The electromagnetic contactor includes means for detecting the position of the adjustable core to detect the state of the controlled switch.

Description

technical field [0001] The present disclosure relates to an electromagnetic contactor, and more particularly to the control of the off or on state of such a contactor. Background technique [0002] Magnetic contactors or power relays are electronic components that ensure power switching. [0003] The voltage levels involved may be, for example, about 115 volts alternating current (VAC), 230 VAC, or even, for example, about 540 volts direct current (VDC). [0004] Magnetic contactors can support current levels on the order of tens to hundreds of amperes. [0005] Electromagnetic contactors, usually remotely actuated by a control signal, consist of one or more electromagnetic field generators equipped with an adjustable core whose displacement provides switching of a controlled switch. [0006] can refer to figure 1 and figure 2 , which shows two embodiments of an electromagnetic contactor according to the prior art. [0007] exist figure 1 In the embodiment, the electr...
