B&R Industrial Automation X20AI2322 Analog Input Module X20 IO System

The B&R X20AI2322 is a two-channel analog input module for the X20 IO System that accepts 0 to 20 mA or 4 to 20 mA signals with a 12‑bit analog-to-digital converter and differential inputs. It occupies one analog slot on the CAN I/O backplane and delivers a 300 μs conversion time per channel with channel-to-bus isolation for safe, modular I/O in industrial environments. Each channel provides protection against wiring with supply voltage and permits up to ±50 mA input (maximum load < 400 Ω); backplane power draw is 0.01 W while the I/O electronics draw about 0.8 W. The device reports its status via per‑channel indicators and carries the B&R ID code 0xCAB2. Certifications include CE and UL/cULus listings among other approvals per the datasheet, and the module is designed for use in X20 CAN I/O networks, enabling straightforward diagnostics and integration with B&R controllers.
