IC630CPU301B GE CPU/Programmer Unit

(1) CPU module
The CPU module is mainly composed of a microprocessor (CPU chip) and memory, in the programmable controller system, the CPU module is equivalent to the human brain and heart, it constantly collects input signals, executes user programs, and refreshes the system’s output. Memory is used to store programs and data.
(2) I/O module
The input (Imput) module and output (Ouut) module are called module 0. They are the eyes, ears, hands and feet of the system, and the bridge connecting the field CPU module. The input signal is received and collected by the input module. There are two types of input signals: one is the input signal from the button, the selection switch, the digital code switch, the limit switch, the proximity switch, the photoelectric switch Q, the pressure relay and other switches. The other is the continuously changing analog input/output signal voltage provided by potentiometers, thermocouples, tachometers, and various transmitters, such as 24V DC and 220V AC. Sharp voltage and interference noise introduced from the outside may damage the components in the CPU block, or use the programmable controller is not working properly, in the 10 module, the photoelectric adapter, photoelectric controllable brick, small relay and other devices to isolate the external input circuit and load, 10 module in addition to transmitting signals, there are level conversion and isolation.
