Functional FeaturesHigh-Precision Signal Acquisition

Utilizing 16-bit high-resolution AD conversion technology and combining with ±0.05% F.S. input accuracy, it precisely captures subtle signal changes, stably and accurately converting various analog signals into digital quantities. This provides reliable data for monitoring key parameters such as temperature, pressure, and flow, meeting high-precision application requirements like precise temperature monitoring in chemical reactors and pressure data collection for precision instruments.

Flexible Adaptation to Diverse Signals

Supporting multiple analog input types including voltage, current, thermocouples, and RTDs, it is compatible with different sensors and detection devices. Whether it is a pressure transmitter requiring voltage signal transmission or a flow sensor relying on current signal feedback, seamless integration is achieved, significantly enhancing the module's versatility and compatibility in various automation systems.

High-Speed Communication and Real-Time Response

Equipped with Profibus DP or optional Ethernet communication interfaces, it supports mainstream industrial communication protocols like Modbus TCP and Profinet, ensuring stable and efficient data transmission. With a maximum sampling frequency of 100Hz, it rapidly collects and uploads signal data, promptly responding to control system commands to ensure real-time monitoring of equipment operation status, effectively improving the overall response speed and collaborative efficiency of the automation system.

Reliable Electrical Isolation Design

Each input channel adopts optoelectronic isolation technology with an isolation voltage of up to 1500V AC, effectively resisting external electromagnetic interference, preventing signal crosstalk and the spread of electrical faults, and protecting backend equipment. Even in harsh environments with strong electromagnetic interference, such as steel plants and substations, it ensures the stability and accuracy of signal acquisition.

Intelligent Diagnosis and Convenient Maintenance

Supporting hot-swapping, faulty modules can be replaced online to reduce downtime. The built-in intelligent diagnosis system real-time monitors channel status, signal anomalies, and other information, visually displaying the operation status through LED indicators. Combined with the communication interface for uploading fault codes, it facilitates quick positioning and troubleshooting, reducing maintenance difficulty and costs.

Wide-Temperature Operation and High Reliability

With a wide operating temperature range of -20°C to +60°C, it adapts to different environments such as high-temperature workshops and cold warehouses. Using industrial-grade high-quality components that have undergone strict aging tests and reliability verification, it features overvoltage, overcurrent, and overtemperature protection functions, ensuring stable and reliable long-term continuous operation and reducing equipment failure rates.

Application FieldsPower Systems

In power plants and substations, it monitors parameters such as generator winding temperature, grid voltage/current, transformer oil temperature, and circuit breaker operating mechanism pressure, real-time collecting and uploading data to the power monitoring system. This provides data support for stable power system operation, fault early warning, and diagnosis, ensuring reliable power supply.

Chemical Industry

In chemical production processes, it accurately collects signals such as reactor temperature, pressure, liquid level, flow, and material concentration/pH value in pipelines, providing accurate data for production process control and safety interlock protection. This ensures chemical reactions proceed under optimal conditions, improving product yield and quality while guaranteeing production safety.

Intelligent Manufacturing

Applied to automated production lines such as automobile manufacturing and electronic assembly, it monitors robotic arm joint temperature, pressure sensor data, conveyor belt speed feedback signals, etc., enabling real-time monitoring of equipment operation status and fault early warning. Combined with control systems, it optimizes production processes and enhances the automation and intelligence level of production lines.

Energy Management

In energy management systems of intelligent buildings and industrial plants, it collects flow, pressure, and temperature signals of energy consumption (water, electricity, gas) and refrigeration/heating parameters of air conditioning systems. Through data analysis, it optimizes energy distribution, assisting enterprises in energy conservation, emission reduction, and operational cost reduction.

Process Control

In industries such as petroleum, metallurgy, and pharmaceuticals, it real-time monitors process parameters like pipeline pressure, liquid level, and material ratio, providing accurate data for DCS (Distributed Control System) to achieve automated regulation and optimization of complex processes, ensuring stable and efficient production.
