Novel sleep mode electromagnetic relay and control device

Abstract

The invention discloses a novel sleep mode electromagnetic relay. The novel sleep mode electromagnetic relay comprises an electromagnetic relay body. A sleep mode control module is arranged in an electromagnetic relay shell. The sleep mode control module is provided with a pull-in voltage access port, a pull-in signal access port, an access port for one end of a coil, a grounding port, an access port for keeping the pull-in working voltage and an access port for the other end of the coil. The two ends of the electromagnetic relay coil are connected with the two access ports used for the coil and arranged on the sleep mode control module respectively. The other four ports in the sleep mode control module are respectively led out of an electromagnetic relay base. An IC1 special for the electromagnetic relay body comprises a pull-in voltage access pin, a pull-in signal access pin, a grounding pin and an access pin for keeping the pull-in working voltage. In the working process, the pull-in sleep is achieved for the pull-in voltage, and pull-in work is kept through the pull-in working voltage lower than the pull-in voltage. Due to the technology of the electromagnetic relay sleep mode, the running targets of being low in voltage and low in power are achieved for the novel sleep mode electromagnetic relay.

Description

technical field [0001] The invention relates to a novel dormant mode electromagnetic relay and a control device, belonging to the technical field of relays. Background technique [0002] For a long time, there is a significant difference in energy consumption between the pull-in coil and the pull-in coil of the traditional electromagnetic relay, resulting in unnecessary waste of energy. This is because: In order to overcome the resistance generated by air reluctance, when the moving contact of the electromagnetic relay pulls in, the coil needs to apply a large driving current. Since the applied driving current cannot be controlled, the electromagnetic relay will operate under this driving current. Keep jobs running. The inherent disadvantage of high current consumption of electromagnetic relay coils can no longer meet the environmental protection requirements of resource conservation, and has also become an obstacle to its development in the direction of low power, low volt...
