Controller module with high protection level and good electromagnetic compatibility

Abstract

The invention provides a controller module with high protection level and good electromagnetic compatibility. The problem that a programmable logic controller module is low in protection level and poor in electromagnetic compatibility is mainly solved. A controller module shell is designed to be of a box type splicing structure, each controller module is a standard independent unit and can be combined and expanded, a wiring bottom plate is installed at the inner side of a controller module shell box body, a functional circuit board is installed at the inner side of a shell box cover, and the wiring bottom plate and the functional circuit board are connected through an inter-board connector. The wiring bottom plates of the adjacent controller modules are connected by flat cables; and an external cable passes through a module cable joint and then is connected to the wiring terminal of the wiring bottom plate. A series of controllers adopting the structure have good electromagnetic compatibility. After the controller module passes through the environment and electromagnetic compatibility tests, the environment and electromagnetic compatibility tests do not need to be repeatedly carried out on a system built by the modules, and a large amount of system manufacturing and testing cost can be saved for a user.

Description

technical field [0001] The invention relates to a controller module with high protection level and good electromagnetic compatibility performance, which belongs to the field of electrical auxiliary equipment and is mainly used in military industry, nuclear power and other fields with strict requirements on electromagnetic compatibility and protection performance. Background technique [0002] Current Programmable Logic Controller (PLC) modules generally use low-level plastic casings, which do not have waterproof and dustproof capabilities, and have poor electromagnetic compatibility. They cannot be exposed to the air and need to be installed in control boxes or control cabinets. , increasing the design and manufacturing costs of the system. For military industry, nuclear power and other fields that have strict requirements on electromagnetic compatibility and protection performance, even if the content is the same, the configuration and structural form are different, electro...

Problems solved by technology

[0002] Current Programmable Logic Controller (PLC) modules generally use low-level plastic casings, which do not have waterproof and dustproof capabilities, and have poor electromagnetic compatibility. They cannot be used exposed to the air and need to be installed in control boxes or control cabinets. , increases system design and manufacturing costs

For military industry, nuclear power and other fields that have strict requirements on electromagnetic compatibility and protection performance, even if the content is the same, the configuration and structural form are different, electromagnetic compatibility and environmental tests are required, which increases a lot of test costs
