微机PLC在机床电液自动控制系统中的应用

Application of the Micro-computer PLC in Automatic Regulation System of Electronic-hydraulic Control Machine Tools

介绍了由单片机 80 31及交、直流固态继电器组成的微机 PLC控制系统 ,对机床电、液开关量实行自动控制 。

The working principle of the micro-computer PLC control system is introduced which consists of SCM 8031,alternating current (AC-SSR) and direct current solid-state relay (DC-SSR).The electronic and hydraulic on-off of machine tools can be controled automatic ally by this system,with various kinds of control logic being available.
