System Description

Schematic Diagram

Control Section

A PLC (Programmable Logic Controller) is a highly autonomous control device designed to perform programmable control. Based on semiconductor technology, it provides not only basic sequence control functions but also advanced functions such as mathematical operations, replacing conventional relay-, timer-, and counter-based control systems.
