SQ-300i-8700700-004 Controller module is one of the core components of the Programmable controller (PLC). PLC is an industrial control device used to monitor and control industrial processes. The controller module mainly includes CPU module, input module, output module and programmer.

CPU module: SQ-300i-8700700-004 is mainly composed of a microprocessor (CPU chip) and memory, equivalent to the human brain and heart. It continuously collects input signals, executes user programs, and refreshes the output of the system. Memory is used to store programs and data.

I/O module: including Input (Input) module and Output (Output) module, they are the eyes, ears, hands, feet of the system, is the bridge connecting the external field and CPU module. The input module is used to receive and collect input signals, which can be input signals from switches such as buttons and select switches, or continuously changing analog input signals provided by potentiometers and thermocouples. The output module is used to output the processed signal to the external device to drive the actuator to work.

The function of the controller module is to receive and process the input signal, perform the corresponding control operation according to the preset program, and output the result to the corresponding executive mechanism. It is the most core part of PLC, responsible for the realization of the entire system control logic and computing processing.

If a controller module is faulty, the entire system may not work properly. Common fault symptoms include the display of the module is Module fault, and the module inspection indicator is blinking. The cause of the failure may be voltage/current interference in the module, module coding error, failure of the startup control line between the module and the controlled device, etc. In the event of a failure, the equipment needs to be inspected and repaired to ensure the normal operation of the system.

In general, SQ-300i-8700700-004 controller module is the core part of the programmable controller, responsible for the realization of the system's control logic and operational processing. Its normal operation is crucial to the stability and reliability of the whole system.
