Application Fields

• Power System: It can receive signals from power sensors, monitor the operating status of the power system in real time, and ensure the safe and stable operation of the power system.
• Industrial Automation: In the automated production lines of industries such as numerical control machinery, metallurgy, oil and gas, petrochemicals, chemicals, papermaking and printing, textile and dyeing, machinery, electronics manufacturing, and automobile manufacturing, it is used to collect status signals of on-site equipment and provide data support for automated control.
• Municipal Engineering: In fields such as water treatment / environmental protection, municipal engineering, and boiler heating, it is used to monitor and control the operating status of related equipment to realize automated management and optimized operation.

• Signal Receiving: The module is connected to external equipment through the input interface, such as safety switches, limit switches, proximity sensors, etc. The signals output by these devices (usually high level or low level) are received by the input channels of the module. For example, when an external switch is closed, a corresponding electrical signal will be generated, and this signal will be captured by the input module.
• Isolation and Filtering: The module contains components such as optocouplers, which can isolate external signals from internal circuits to prevent electrical interference from affecting the operation of the module and subsequent equipment. At the same time, the filter circuit will process the received signal to remove noise and clutter in the signal, ensuring the purity and stability of the input signal.
• Signal Conversion: The signal after isolation and filtering will be converted into a logic level signal that can be recognized by the internal module and the central processing unit, usually represented in the form of binary “0” and “1”. For example, an external high – level signal is converted into an internal logic “1”, and a low – level signal is converted into an internal logic “0”.
• Status Indication: The module provides a diagnostic LED for each input. According to the converted logic level signal, the corresponding LED will light up or go out to indicate the status of the connected equipment, which is convenient for operators or maintenance personnel to intuitively understand the working status of external equipment and the signal input status.
• Signal Transmission: The converted digital signal is transmitted to the central processing unit (such as the CPU of PLC) through a specific interface and bus. The central processing unit performs logical operations and judgments based on these input signals, and then controls the operation of the entire system to realize functions such as monitoring and control of industrial processes.
