ABB UAD215A106 3BHE026284R0106 Processor

Input Power Supply: Supports 24VDC DC power supply, with excellent power adaptability, allowing a voltage fluctuation range of ±15%, which can effectively cope with the unstable power supply in industrial sites. The rated power consumption is about 13W, which conforms to the concept of energy-saving design, reducing energy consumption while ensuring performance.

Signal Input: Equipped with 16 analog input channels, widely compatible with common signal types such as 4-20mA, 0-20mA, 0-5V, 0-10V. Each channel is equipped with independent electrical isolation, with an isolation voltage of up to 3000VAC, which largely avoids crosstalk between signals and ensures the accuracy and stability of signal acquisition.

Signal Output: Includes 8 analog output channels, the output signal can be flexibly configured as 4-20mA or 0-10V, the output accuracy reaches ±0.05% FS, and the linearity error is ≤0.03%, which can accurately execute control commands and provide precise signal drive for equipment operation.

Digital Interface: Provides 24 digital inputs (24VDC, sink/source type can be selected according to actual needs) and 20 digital outputs (24VDC, maximum load current 2A). The response time is extremely short, all ≤0.3ms, meeting the strict requirements for fast response in high-speed switch control scenarios.

Communication Interface: Integrates 2 RS-485 serial ports, fully supporting Modbus RTU protocol, and the transmission rate can be adaptively adjusted within the range of 9600-115200bps; at the same time, it is equipped with 1 Gigabit Ethernet interface, supporting mainstream industrial protocols such as Modbus TCP/IP and Profinet, facilitating the construction of a high-speed and stable industrial communication network and realizing efficient data interaction between devices.

Working Environment: The working temperature range is extremely wide, and it can work normally from -40℃ to +75℃, and the relative humidity is allowed to fluctuate in the range of 5%-95% (no condensation). The protection level is IP20, suitable for installation in industrial control cabinets, and can withstand harsh environmental conditions such as high temperature, low temperature and humidity, ensuring stable operation under different working conditions.

Mechanical Specifications: The product size is 150mm×100mm×70mm (length × width × height), adopting DIN rail mounting method. This mounting method is not only convenient, but also can effectively save space, provide convenience for system integration, and make the equipment layout more compact and reasonable.

Excellent Signal Isolation and Processing Technology: Adopts advanced magneto-optical fusion isolation technology, which greatly improves the anti-interference ability compared with the traditional single magnetic isolation or photoelectric isolation methods. It can effectively suppress common interference sources in industrial sites such as strong electromagnetic pulses (EMP), radio frequency interference (RFI) and common-mode voltage, ensuring high accuracy of signals during acquisition and transmission. Taking the industrial scenario where large motors start frequently as an example, this module can effectively avoid the impact of strong electromagnetic interference generated at the moment of motor startup on sensor data acquisition, ensuring that the system obtains accurate on-site signals.

Intelligent Signal Adaptation Function: With the help of special configuration software, users can customize the signal type and range of analog input/output according to actual needs. At the same time, it supports direct acquisition and conversion of temperature signals from thermal resistors (such as Pt100, Pt1000) and thermocouples (Type K, Type J, Type T, etc.) without additional transmitters, which significantly reduces the system integration cost, enhances the adaptation flexibility to different types of sensors, and can better meet the diversified industrial application needs.

Comprehensive Real-time Diagnosis and Early Warning Mechanism: The module has a powerful real-time diagnosis function, which can continuously monitor various states such as disconnection, short circuit, over-range of input signals, abnormal power supply of the module, communication failure and internal circuit failure. Once an abnormality is detected, it will be displayed intuitively through LED indicators immediately, and detailed fault codes and diagnostic information will be output through the communication interface, while supporting remote early warning function. This feature greatly facilitates operation and maintenance personnel to quickly locate the root cause of the problem, effectively shortens the fault handling time, reduces the risk of equipment shutdown, and ensures the continuity of production.

Triple Redundancy Design Ensures High Reliability: Supports power redundancy, communication redundancy and key circuit redundancy design. When the main power supply, main communication link or key circuit fails, the system can automatically and seamlessly switch to the backup path within an extremely short time of 30ms, ensuring the uninterrupted operation of the entire system. This high-reliability design makes it particularly suitable for application scenarios with high requirements for system stability, such as nuclear power plant auxiliary equipment control, chemical continuous production process control and other fields, providing a solid guarantee for the stable operation of key industrial processes.

Ultra-high Mechanical Stability: It has passed strict vibration (10-500Hz, 20g acceleration) and impact (60g acceleration) tests, and can withstand severe vibration and impact generated during the operation of industrial on-site equipment. Its mean time between failures (MTBF) is as long as 200,000 hours, which fully proves the high stability of the module in long-term use, can effectively reduce the frequency of equipment maintenance, lower the operation and maintenance cost, and improve the overall efficiency of industrial production.
