Built in standardized signal processing algorithms for different industrial scenarios, while supporting users to customize algorithm logic through dedicated development software, to achieve accurate analysis and feature extraction of various complex signals.

3. Multi mode closed-loop regulation and control

Supports multiple closed-loop adjustment modes such as voltage regulation, current regulation, speed regulation, displacement regulation, etc., and can be flexibly switched according to application scenario requirements. Built in high-precision PID regulator and adaptive adjustment algorithm, it can output precise adjustment instructions in real time based on the deviation between the signal processing results and the set threshold, ensuring that the controlled parameters are stable within the set range, with small overshoot and fast adjustment response, improving system operation stability and control accuracy.

4. Comprehensive signal monitoring and fault diagnosis

Equipped with full process signal monitoring function, it can detect input signal distortion, signal loss, over range, and abnormal operation of the board itself (such as overheating, overvoltage, circuit faults, etc.) in real time. Built in fault diagnosis algorithm can quickly identify fault types and record fault information, trigger fault alarm signals in a timely manner, and perform corresponding protection locking actions to avoid equipment damage caused by the expansion of faults and ensure the safe operation of the system.

5. Multi protocol communication and system collaborative interconnection

Built in RS485, CANopen, Ethernet and other mainstream industrial communication interfaces and protocol processing units can achieve high-speed data exchange with upper monitoring systems, lower actuators, sensors and other control modules. Supporting the construction of distributed control networks, it can serve as a signal processing core node to achieve multi device collaborative regulation, improving the overall system's collaborative operation efficiency and scalability.

6. Flexible configuration and remote operation and maintenance management

Support signal processing parameter configuration, adjustment algorithm parameter debugging, and program upgrade through dedicated software, with offline programming and online debugging functions, suitable for on-site debugging and later system upgrade requirements. Supporting remote communication and status monitoring, operation and maintenance personnel can remotely obtain signal processing data, equipment operation status, and fault information, achieving remote diagnosis and parameter optimization, reducing operation and maintenance costs and on-site workload.
