1. Input Circuit Wiring The input circuit is the port through which the PLC receives signals (for analog signals, it is generally a DC current of 0-40MA or a DC voltage signal of 0-10V). Input wiring refers to the external input devices (any passive contacts and NPN transistors with open collector) that connect to the … Read more

In modern industrial production equipment, there are numerous digital and analog control devices, such as motor start/stop, electromagnetic valve opening/closing, product counting, and the setting and control of temperature, pressure, and flow. For these automatic control issues in industrial sites, Programmable Logic Controllers (PLCs) have become one of the most effective tools for resolution. So, … Read more
