Description

technical field

[0001] The invention relates to the technical field of relay wiring, in particular to an electric control element and a circuit control system. Background technique

[0002] The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system and the controlled system, and is usually used in automatic control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current.

[0003] In the wiring of the existing relay, it is necessary to add terminal blocks, cables, etc. externally. The wiring is complicated, which affects the EMC performance of the product and takes up valuable space in the electric control box. Contents of the invention ...
