B&R Industrial Automation X20AI4622 4-Channel Analog Input Module

X20AI4622 is a four-channel analog input module for B&R's X20 I/O system, designed to collect signals from sensors and transducers in industrial automation. It supports four independent inputs in either voltage mode (±10 V) or current mode (0–20 mA / 4–20 mA), with a 13‑bit ADC delivering precise digital values. Each channel can be configured to the desired input range and features a configurable input filter to reduce noise in rugged environments. The module mounts on an X20 terminal block with 12-pin connections and integrates with the X20 fieldbus for straightforward configuration and mapping to the controller I/O. Typical applications include process monitoring, machine control, and data acquisition where multiple analog sensors must be read in real time. The X20AI4622 is part of B&R's X20 analog input family and inherits a compact form factor and plug‑in compatibility, enabling scalable expansion of an automation system without changing software structures.
