Working principle
After the module is powered on, it first performs self check initialization to check the internal hardware (such as processor, memory, communication interface, etc.) to ensure that all components are working properly. After the self check is completed, real-time collection of connected sensor signals begins. For digital input signals, the external DC 24V switch signal is converted into a recognizable logic level signal within the module through an input circuit; For analog input signals, continuous analog signals are converted into digital signals through signal conditioning circuits (including filtering, amplification, A/D conversion, etc.), and then transmitted to the central processing unit (CPU).
The CPU performs logical operations, data processing, and analysis on the collected data based on pre written and stored control programs in memory. For example, comparing the currently collected temperature data with the preset temperature range to determine whether heating or cooling equipment needs to be activated. According to the calculation results, the CPU generates corresponding control instructions, converts digital signals into physical signals suitable for driving actuators through output circuits (such as digital output switch signals, analog output voltage/current signals), drives actuator actions, and achieves control of industrial equipment.
Throughout the entire work process, the module maintains real-time communication with external devices through communication interfaces, receives control commands and parameter settings from the upper computer, and provides feedback on the device’s operating status, data information, etc. to the upper computer and other related devices, achieving collaborative operation and intelligent management of industrial systems.

Core functions
Electricity transmission: The core function of power lines is to stably and efficiently transmit the electricity from the mains to the equipment, ensuring the normal operation of various components inside the equipment. Its good electrical performance can ensure smooth current flow, avoid damage to electronic components caused by current fluctuations, and provide solid guarantees for the stable operation of equipment.
Electrical isolation: While transmitting electrical energy, the power line also has electrical isolation function. It can effectively block the possible stray currents and electromagnetic interference between the equipment and the mains power, prevent external interference signals from entering the equipment through the power line and affecting the normal operation of the equipment, and also avoid the interference generated inside the equipment from feedback to the mains power network and affecting other electrical equipment.
Working principle
When the power cord plug is inserted into the mains socket, the electrical energy from the mains enters the conductors inside the power cord through the metal pins of the plug. Due to the use of copper material with good conductivity, electrical energy is transmitted in the form of electron flow in the conductor, flowing from one end of the plug to the device end. During cable transmission, the insulation material on the outer layer prevents electrical energy from leaking out, ensuring that electrical energy is only transmitted inside the conductor. After reaching the device end, the electrical energy enters the internal power management module of the device through its power interface. This module further converts and stabilizes the input electrical energy, and then distributes it to various components of the device to drive it to operate normally.
Precautions for use and maintenance
Correct connection: When connecting the power cord, be sure to turn off the device power first to ensure safe operation. Insert correctly according to the device interface identification and power cord interface shape to avoid poor contact, inability to start the device properly, or even damage to the device and power cord due to reverse or improper insertion.
Regular inspection: During use, regularly check whether the power cord is damaged, aged, or overheated. If the outer sheath of the cable is found to be damaged, the power cord should be replaced in a timely manner to prevent leakage and safety accidents; If the power cord generates abnormal heat during use, it may be due to excessive current or poor internal conductor contact. It is necessary to immediately stop using and investigate the cause.
Storage requirements: When the power cord is not in use, it should be neatly arranged to avoid entanglement and knotting, and to prevent damage to the internal conductor due to excessive bending. The storage environment should be kept dry and ventilated, and the power cord should be protected from direct sunlight, high temperatures, or corrosive substances.

Receive signals from on-site devices such as pressure sensors, limit switches, and temperature transmitters, which are divided into digital quantities (switch status, such as ON/OFF) and analog quantities (continuously changing values, such as 4-20mA current, 0-10V voltage).
Digital input: Isolating external circuits through optocouplers to prevent interference, converting level signals (such as 24V DC) into logic signals (0/1) recognizable by the controller.
Analog input: Continuous analog signals (such as voltage and current) are converted into digital signals (such as 12 bit or 16 bit binary numbers) through an analog-to-digital converter (ADC), and filtered and linearized to reduce the impact of noise.
Signal isolation and protection:
Adopting electrical isolation technology (such as optocouplers and transformer isolation) to avoid the impact of on-site equipment failures on the controller, while suppressing electromagnetic interference (EMI) and common mode voltage interference. For example, the isolation voltage can usually reach 500V~2500V to ensure system safety.
