B&R Industrial Automation X20AI2622 PLC Module

The X20AI2622 is a compact two‑channel analog input module in B&R's X20 I/O system, designed to reliably capture sensor signals in industrial automation. Each channel supports either a voltage input in the ±10 V range or a current input in 0–20 mA / 4–20 mA with differential signaling, delivering 13‑bit resolution (including sign) per channel and a fast 300 μs conversion time for both inputs. The module presents a high‑impedance input path for voltage signals (about 20 MΩ) and provides per‑channel measurements as integer values with 2.441 mV per LSB for voltage and 4.883 μA per LSB for current; the B&R ID code is 0x1B9E and status is made available via LED indicators and software. Power consumption is 0.01 W from the backplane bus plus up to 0.8 W for internal I/O. The X20AI2622 carries CE and UKCA markings and is approved for hazardous locations with ATEX Zone 2 (II 3G Ex nA nC IIA T5 Gc IP20, Ta) certifications; it is also UL/cULus E115267 and cCSAus 244665 certified, supporting global deployment. Typical applications include sensor signal acquisition for process control and machine automation within B&R projects, enabling precise monitoring of ±10 V sensors or 4–20 mA loop devices in industrial environments.
