Zusammenfassung:An electromagnetic contactor module is provided to avoid a tripping event by setting a variable duty cycle with an astable mode of operation. An electromagnetic contactor module(100) includes a control module(1). The control module includes a power circuit and an analog control circuit. The power circuit includes a coil assembly(3), and receives an AC or DC supply voltage. The analog control circuit is communicated with the power circuit, and monitors a coil voltage inside the coil assembly. A reset input about an astable pulse generated from a pulse generator in response to a coil voltage larger than a predetermined dropout voltage is set into high.
