Abstract
A communication device for an electrical switching unit that includes an actuator driven by a control circuit. The communication device includes: a connector that can be connected to the control circuit, to receive a state signal sent by the control circuit and to receive an electrical power supply voltage supplied by the switching unit; a capacitor configured to be recharged from the power supply voltage received from the input connector when the state signal takes a predefined value; a bistable relay comprising a normally-open electrical contact connected to output terminals to form a dry electrical contact; and a pulse generator supplied by the capacitor and being configured to excite the bistable relay when the capacitor reaches a predefined level of charge.
Claims14
A low-power-consumption communication device for an electrical switching unit, said electrical switching unit comprising an actuator driven by a control circuit, the communication device comprising:
- a connector that can be connected to the control circuit, to receive a state signal sent by the control circuit and to receive an electrical power supply voltage supplied by the switching unit;
- a capacitor configured to be recharged from the power supply voltage received from the input connector when the state signal takes a predefined value;
- a bistable relay comprising a normally-open electrical contact connected to output terminals of the communication device to form a dry electrical contact;
- and
- a pulse generator supplied by the capacitor and being configured to excite the bistable relay and thus switch the electrical contact when the capacitor reaches a predefined level of charge.
