Overview

ABB Bailey IEMMU21 is a high-performance analog input module belonging to the ABB Bailey INFI 90 open distributed control system series. It undertakes a key signal acquisition task in industrial automation process control. It can accurately receive signals from various analog sensors such as temperature, pressure, and flow sensors, convert them into digital signals, and transmit them to the control system, providing precise original data support for the monitoring and regulation of industrial production processes.

With its excellent measurement accuracy, stable signal processing capability, and good system compatibility, this module can be seamlessly integrated into the INFI 90 distributed control system. It is widely used in industrial fields such as electric power, chemical industry, and metallurgy, where high requirements are placed on the accuracy and reliability of analog signal acquisition. It is an important component to ensure the stable operation of industrial processes.

Technical Parameters

Power Parameters: The working power supply is 24V DC, with an allowable voltage fluctuation range of ±10%, which can adapt to voltage fluctuations in industrial on-site power supplies and provide reliable power guarantee for the stable operation of the module.
Input Channels: Equipped with 8 independent analog input channels, which can collect multiple analog signals simultaneously to meet the needs of simultaneous monitoring of multiple parameters in industrial sites.
Input Signal Types: Supports various standard analog input signals, including 4-20mA DC current signals, 0-10V DC voltage signals, etc. It can be adapted to multiple types of sensors such as thermocouples (e.g., K-type, J-type) and thermal resistors (e.g., Pt100), with strong compatibility.
Measurement Accuracy: Within the full range, the measurement accuracy is usually ±0.1% FS (Full Scale), ensuring accurate acquisition of analog signals and providing high-quality data basis for the control system.
Isolation Performance: Electrical isolation design is adopted between each input channel and between channels and the power supply, with an isolation voltage of up to 2500V AC, effectively preventing signal interference between channels and external interference, and improving the anti-interference ability of the system.
Sampling Rate: The sampling rate of each channel is relatively high, usually up to more than 10 times per second, which can quickly capture the dynamic changes of analog signals and meet the monitoring needs of rapidly changing processes.
Environmental Parameters: The operating temperature range is 0℃-+60℃, and the storage temperature range is -40℃-+85℃; the relative humidity is 5%-95% (non-condensing); the protection level is IP20, suitable for installation in control cabinets to prevent dust intrusion.
Dimensions: Adopting a compact design, the dimensions are approximately 160mm×100mm×80mm (length × width × height, subject to the actual product), which is convenient for installation and layout in the control cabinet, saving space.

Functional Features

High-Precision Signal Acquisition: The 8 analog input channels have a measurement accuracy of ±0.1% FS. Combined with a high sampling rate, they can accurately capture subtle changes in analog signals such as temperature and pressure, providing reliable original data for industrial process control and ensuring that the control system makes accurate decisions.
Compatibility with Multiple Signal Types: Supports various standard signals such as 4-20mA and 0-10V, as well as thermocouple and thermal resistor signals. It can be directly connected to various sensors without additional conversion equipment, simplifying system wiring and integration processes and reducing equipment costs.
Strong Anti-Interference Ability: Through the high-voltage isolation design between channels and with the power supply, it can effectively resist electromagnetic interference, common-mode interference, etc. in industrial sites, ensuring the stability and accuracy of collected signals, reducing measurement errors caused by interference, and improving the reliability of the system.
Convenient System Integration: As a standard module of the INFI 90 distributed control system, it can be seamlessly connected with other modules in the system (such as controllers, output modules, etc.), realizing rapid data transmission and sharing through the system bus, simplifying the system construction process and shortening the project implementation cycle.
Diagnosis and Maintenance Functions: Equipped with a complete self-diagnosis function, it can real-time monitor the working status of the module, such as channel faults and power abnormalities, and upload fault information to the controller through the system bus, facilitating maintenance personnel to discover and eliminate faults in a timely manner and improving the maintainability of the system.
