Abstract

The invention relates to a contactless digital controller, and belongs to the technical field of electricity. The controller replaces a master electrical appliance with an electronic circuit and replaces an alternating-current contactor with a soft contact button and a two-way silicon controlled rectifier (SCR); the controller is provided with a LM 324 quad operational amplifier integrated circuit, and a resister is connected with a diode to form a trigger and a voltage comparator; the shifting multi-speed self-latching and interlocking of a motor tap form a main control circuit (1); a driving circuit (2) consists of a COM 3061 photoelectric coupler; the output end of a driving part (2) drives a main driving circuit (3) consisting of the two-way silicon controlled rectifier (SCR) directly through a line bank; the main driving circuit (3) is directly connected with a main winding terminal post and a tap terminal post of a motor through the line bank; a corotation button W1 and reversion button W3 in the main control circuit (1) adopt dual contacts (W1A, W1B and W3A and W3B) to form a Y-delta starting circuit along with an NE555 time base circuit.

Description

technical field [0001] The invention belongs to the technical field of electricity and relates to a point controller. Background technique [0002] The prior art close to the present invention is the AC contactor controller circuit controlled by traditional master electric appliances (buttons, travel switches, time relays, relays, etc.). Both the master electrical appliance and the AC contactor are contactors, which have short life, are not dust-proof, are not explosion-proof (with contact sparks), are not moisture-proof, are not suitable for harsh environments, are large in size, high in cost, and have relatively loud noises in operation. Energy saving and other disadvantages. Contents of the invention [0003] The purpose of the present invention is to provide a non-contact digital controller to solve the problem that the prior art controller has contacts, short life, no dustproof, no explosion-proof (with contact spark), no moisture-proof, not suitable for harsh enviro...
