ABB 3BHE021951R0124 Frequency I/O Board

Input Channel Configuration: Equipped with 16 independent analog input channels. This multi-channel design can meet the needs of simultaneous acquisition of multiple signals in industrial sites. It supports a variety of signal types, including 4-20mA, 0-20mA current signals, and 0-10V, -10-10V voltage signals. It can perfectly adapt to most on-site instruments such as temperature transmitters, pressure sensors, and flow meters on the market without the need for additional signal conversion equipment.

Measurement Accuracy Performance: The resolution reaches 16 bits, which means it can capture extremely small signal changes. The measurement accuracy is as high as ±0.1% FS (full scale), ensuring that the collected data is highly accurate and reliable, providing high-quality raw data for the control system.

Sampling and Response Capability: The maximum sampling rate of each channel is 100Hz, which can quickly capture the dynamic changes of on-site signals and accurately record parameters that change rapidly (such as instantaneous pressure fluctuations). At the same time, the module has a fast response speed and can process and transmit the collected signals in a timely manner.

Isolation and Protection Performance: Advanced optoelectronic isolation technology is adopted between channels and between channels and the backplane, with an isolation voltage of up to 2.5kV. This strong isolation capability can effectively suppress common-mode interference and differential-mode interference common in industrial sites, avoiding mutual interference between different signals and ensuring the stability and accuracy of signal acquisition.

Power Parameter Specifications: The working power supply is 24V DC, which meets the standard power supply requirements of industrial sites. The rated power consumption is about 8W, which is a low-power device, helping to reduce the overall energy consumption of the system. The power supply fluctuation adaptation range is ±10%, which can cope with the unstable power supply voltage in industrial sites to a certain extent and ensure the stable operation of the module.

Environmental Adaptability: The operating temperature range is -25℃ to 70℃, allowing it to work normally even in cold or hot industrial environments; the storage temperature range is -40℃ to 85℃, facilitating storage under different conditions. The relative humidity is 5%-95% (non-condensing), enabling it to adapt to humid environments. In addition, it has good anti-vibration performance (10-500Hz, 1g acceleration) and anti-impact performance (25g, 11ms), and can operate reliably in industrial scenarios with vibration and impact (such as machinery factories and metallurgical workshops).

Physical and Installation Characteristics: The size is approximately 120mm×110mm×180mm, with a compact overall structure and a weight of about 0.9kg. It adopts a standardized DIN rail mounting method, which can be easily installed in standard control cabinets. It is well compatible with other modules in the S800I/O series, facilitating system expansion and upgrading.

Communication Interface Configuration: It communicates with the controller through the S800I/O bus and supports redundant communication configuration. This design greatly improves the reliability of data transmission. Even if one communication link fails, the other link can still ensure the normal transmission of data. The communication rate is 12Mbps, which can meet the data transmission speed requirements of industrial control systems.

Wide Signal Compatibility: It supports the input of multiple standard analog signals and can be directly connected to various on-site instruments such as temperature transmitters, pressure sensors, liquid level meters, and flow meters without complex modifications to the module. This greatly enhances the applicability and flexibility of the module in different application scenarios and reduces the difficulty and cost of system integration.

High-Precision Data Acquisition Capability: The 16-bit high resolution and ±0.1% measurement accuracy enable it to accurately capture subtle changes in signals. For example, in chemical production, it can accurately monitor small fluctuations in the temperature inside the reactor, providing accurate data basis for the control system to adjust reaction conditions in a timely manner.

Powerful Anti-Interference Design: In addition to excellent isolation performance, the module also adopts advanced electromagnetic compatibility (EMC) design, which can effectively resist strong electromagnetic interference generated by equipment such as motors, frequency converters, and electric welders in industrial sites. It ensures stable acquisition and transmission of signals in complex electromagnetic environments, guaranteeing the normal operation of the system.

Guarantee of Real-Time Data Transmission: The combination of high sampling rate and efficient communication capability ensures that the collected on-site signals can be transmitted to the control system in real-time and accurately. This enables the control system to timely grasp the on-site operating status, quickly respond to various changes, improves the timeliness and effectiveness of control, and helps avoid production accidents caused by data lag.

Convenient Fault Diagnosis Mechanism: Each channel is equipped with an independent status LED indicator. The on/off status of the indicator can visually show the working status of each channel, such as normal signal input and abnormal signal. At the same time, the module is also equipped with overall power, communication, and fault indicators. Combined with the controller system, it can monitor the overall operating status of the module in real-time and read detailed fault information (such as channel short circuit, signal over-range, etc.), facilitating maintenance personnel to quickly locate and troubleshoot faults, greatly shortening the fault handling time and improving system availability.
