In the design of PLC control systems, although wiring work accounts for a small proportion and most of the work is still PLC programming design, it is the foundation of programming design. As long as the wiring is correct, programming design work can be carried out smoothly. To ensure the correctness of wiring work, it is necessary to have a clear understanding of the input and output circuits inside the PLC. We know that the PLC digital input module is designed to prevent interference from external circuits (such as peak voltage, interference noise, etc.) from causing abnormal operation of the PLC or even damage to components

Generally, optocouplers are used on the input side of PLCs to cut off the electrical connection between internal and external circuits, ensuring the normal operation of PLCs. And RC filtering circuits are installed in the input lines to prevent erroneous signals caused by input point jitter or external interference pulses. The input circuit of PLC can be divided into DC input circuit and AC input circuit according to the type of external power supply; According to the current flow direction of the common terminal (COM terminal) of the PLC input module, it can be divided into source input circuit and drain input circuit; According to the connection method of the common terminal of the optocoupler light-emitting diode, it can be divided into common anode and common cathode input circuits< br />ALLEN BRADLEY PV1000 2711-K10G9 2711K10G9 D NIB
