IC693PWR322 Connecting Wire
IC693PWR322 in the PLC control system design, often encountered load start and stop control, the usual practice is to use two buttons as the external start and stop control of the input device, in the PLC and the two buttons corresponding to the number of input points are also two, PLC’s external wiring as shown in Figure 1.
IC693PWR322 button SB1 (X0) as a start control, button SB2 (X1) as a stop control, so that although you can achieve the purpose of the control, but the need for more buttons and connecting wires, PLC input points are also more. But in practice, you can take full advantage of the PLC internal multifunctionality, using a single button to control the load start and stop, to improve the external wiring of the PLC as shown in Figure 2, with SB instead of SB1 and SB2 functions
IC693PWR322 with X0 instead of X0 and X1 functions, the actual wiring of the circuit is greatly simplified, which not only saves the cost of hardware, but also greatly reduces the number of buttons due to the possible failure. Make the circuit more economical and reasonable, safe and reliable, convenient and simple control, with high practical value.
