LM3107 220VAC power supply, 14 Channels DC24V DI,10 Channels Relay DO PLC
working principle
When the programmable logic controller is put into operation, its working process is generally divided into three stages, namely, input sampling, user program execution and output refresh. Completing the above three phases is called a scan cycle. During the entire run, the programmable logic controller's CPU repeatedly performs the above three phases at a certain scan speed.
