In the design of VT-HNC100-1-23W-08-P-0  control systems, although the proportion of wiring work is relatively small, most of the work is still PLC programming design work, but 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 in order to prevent interference from external circuits (such as peak voltage, interference noise, etc.) that may cause abnormal operation of the PLC or even damage to components, the VT-HNC100-1-23W-08-P-0  digital input module generally uses optocouplers on the input side of the R900958999  to cut off the electrical connection between the internal and external circuits of the PLC, ensuring the normal operation of the PLC. And RC filtering circuits are installed in the input circuit to prevent erroneous signals caused by input point jitter or external interference pulses.

Form of 2 input circuits
2.1 VT-HNC100-1-23W-08-P-0
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 at the common end (COM end) of the PLC input module, it can be divided into source input circuits and drain input circuits; According to the connection method of the common end of the optocoupler light-emitting diode, it can be divided into a common anode and a common cathode input circuit.
