X20AT2222 Advantages
The B&R X20AT2222 I/O Module stands out from comparable RTD temperature input modules in several key areas.
High‑precision 0.1 °C temperature resolution. Fine measurement resolution captures subtle temperature changes on both input channels simultaneously — critical for equipment overheat protection logic and closed‑loop thermal process optimization.
Flexible 2‑wire / 3‑wire RTD support. Compatible with PT100 and PT1000 platinum resistance sensors, allowing field‑side wiring scheme selection without extra external signal conditioning hardware and simplifying cabinet‑side installation work.
Per‑channel configurable digital input filter. The B&R X20AT2222 I/O Module supports adjustable filter time via software parameters, effectively suppressing field electromagnetic noise interference for stable temperature readings in high‑noise plant cabinet environments.
Comprehensive channel‑level self‑diagnostics. The B&R X20AT2222 I/O Module detects sensor open‑circuit, short‑circuit and abnormal measurement conditions, providing fault status information to the X20 CPU for fast troubleshooting and predictive maintenance.
Wide operating temperature range. The B&R X20AT2222 I/O Module performs reliably under variable cabinet thermal conditions for both horizontal and vertical DIN‑rail mounting orientations without additional cooling or heating protection.
Native X20 System integration. As a factory‑original B&R component, the B&R X20AT2222 I/O Module directly mates with compatible X20 terminal blocks and X2X‑Link bus hardware with no extra adapters or custom modification.
