Abstract

The invention relates to a universal type control device used for industry; a mater controller on a microcomputer and a power module, an I / O signal input / output unit, a standard communication interface unit, an adjusting and control unit, an operation keyboard and a display, etc. which are connected on the microcomputer are connected into an integrated device; the invention is characterized in that the integrated device also comprises a power-driven unit; the input of the power-driven unit is a way of three-phase alternating-current supply, and the output is two ways of three-phase alternating-current supply, the output of which is controlled by the adjusting and control unit; as the control unit and the power-driven unit of the invention are integrated, the invention can complete the direct drive to a low-power executing mechanism and indirect drive to a large-power executing mechanism; the connection of the software and the interface of the microcomputer is only changed for different control requirements. The universal type control device of the invention can improve the reliability of the production system largely, is suitable for production on scale and reduces the cost of production, maintenance and use of the control device.

Description

technical field [0001] The invention belongs to an industrial control device, in particular to an industrial universal digital control device. Background technique [0002] Traditional industrial control requires multiple hardware and multiple steps to complete a complete control process for a controlled device. Its fatal weaknesses are: low degree of digitization, complex system, bulky, poor reliability, and difficult maintenance. Contents of the invention [0003] The purpose of the present invention is to provide an industrial general-purpose digital controller integrating strong current and weak current; control and drive; parameter detection and intelligent instrument; fault judgment and alarm protection; production process control and intelligent adjustment; network communication and information management type control device to overcome the above-mentioned deficiencies. [0004] In order to achieve the above object, the present invention connects the main controlle...
