Abstract

The invention relates to an electrical control circuit device for relays, which comprises a main power source module, a relay main control circuit module and a relay circuit module which are connected with the main power source module, wherein the relay main control circuit module controls the working condition of the relay circuit module. The device of the invention comprises a current limiting module which is connected between the main power source module and the relay main control circuit module. By employing the electrical control circuit device for relays, quiescent current only is current of the relay main control circuit module, and action current of the relay circuit module is not included, thereby greatly decreasing quiescent electrical power consumption. Current of most main control circuit modules, however, such as remote control reception, human induce and the like can be small, thereby effectively reducing quiescent current of the relay control circuit and saving energy consumption. The circuit structure is simple, the working properties are stable and reliable, and the applicability is wide, thereby laying a solid foundation for further popularization and application and energy saving of electrical control circuit.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to the technical field of relay electronic control, in particular to a relay electrical control circuit device. Background technique [0002] In the current relay control circuit, generally the control circuit and the relay share a power supply. Regardless of whether the relay is closed or not, the circuit current is relatively large. Especially in the circuit using Zener diode, please refer to Figure 1, when the relay is not closed, the total current of the circuit I=I M +I W , where I M consumed by the main circuit, I W is the current flowing through the Zener diode, the total current I when the relay is closed / = I M / +I W / +I J . [0003] because I M ≈I M / , I W ≈I W / +I J , so I≈I / , that is, I and I before and after the relay pull-in / Basically equal, the actual result is that although the relay does not pull in at static state, the current consume...
