B&R Industrial Automation X20AI2622 Analog Input Module

The B&R X20AI2622 is a two-channel analog input module designed for the X20 I/O system, enabling direct digitization of common sensor signals in BR Automation PLC applications. Each channel can accept either a ±10 V voltage input or a current-loop signal in the 0–20 mA / 4–20 mA range, delivering data through a 13-bit analog-to-digital converter for precise measurement. The module supports a configurable input filter to tailor timing and noise rejection to your environment, helping stabilize readings in electrically noisy industrial settings. As part of the X20 family, the X20AI2622 integrates with BR Automation Studio and the BR backplane, providing deterministic sample timing and straightforward mapping to I/O addresses; its hardware identity in BR catalogs is 0x1B9E (B&R ID code). Typical use cases include machine sensing of voltages and current loops, process control loops, and monitoring analog signals from sensors like pressure transducers, temperature or flow sensors when paired with appropriate signal conditioning.
