The working principle is as follows:
Signal Acquisition Principle
Analog Signal Acquisition
The module has 8 analog input channels, which can receive standard analog signals such as 4-20mA or 0-5V. These signals typically come from various sensors (e.g., temperature sensors, pressure sensors, flow sensors) for detecting physical quantities in industrial processes. The module conditions the received analog signals through amplification, filtering, and other processing to improve signal quality, and then converts them into digital signals via an analog-to-digital (A/D) conversion circuit for processing by the internal microprocessor.
Speed Signal Acquisition
It is equipped with 4 speed input channels, which can connect to magnetoelectric speed sensors or proximity probes. After the speed signal generated by the sensor is input into the module, the module performs filtering processing. The filtering time constant can be selected as 8 ms or 16 ms through application software to remove interference noise from the signal. The module then analyzes and calculates the processed speed signal to obtain the actual rotational speed value, which is provided to the application for speed control and related operations.
Signal Output Principle
Analog Signal Output
The module has 4 analog output channels, which can output analog signals within the range of 4-20mA or other specified ranges to control various actuators (e.g., regulating valves, frequency converters). The internal microprocessor calculates the required control quantity according to the control algorithm, converts the digital signal into an analog signal via a digital-to-analog (D/A) conversion circuit, and outputs it to the actuator after signal amplification and other processing, thus achieving precise control of industrial processes.
Proportional Actuator Output
Two proportional actuator output channels are used to drive proportional actuators. The module outputs corresponding signals to control the actions of proportional actuators (e.g., controlling the opening degree of actuators) according to control requirements to meet specific control needs. The output signal form can be set as 4-20mA, 20-160mA, etc., through configuration.
Data Processing and Communication Principle
The internal microprocessor of the module processes and analyzes various collected signals, calculates corresponding control instructions according to preset control algorithms and logic, and realizes monitoring and control of industrial processes. Meanwhile, it supports multiple communication protocols (e.g., Modbus, Profibus), enabling it to transmit collected data, working status, and other information to the host computer or other monitoring systems through communication interfaces, and receive control instructions and parameter settings from the host computer to achieve functions such as remote monitoring and flexible configuration.
