The A6220 (Ordering Code: 9199-00009) is a specialized two-channel monitoring module engineered for the Emerson AMS 6500 Machinery Health Monitor. This 3U plug-in card is a critical component for the protection of large-scale rotating assets, such as steam turbines, gas turbines, and high-performance compressors. The A6220 (9199-00009) is specifically designed to measure shaft eccentricity—the peak-to-peak displacement of a rotor at low speeds—which is vital for identifying shaft bow or thermal misalignment before the machine transitions through its critical speeds during startup or shutdown.
The A6220 (A6220) integrates high-integrity signal processing with robust diagnostic capabilities to meet API 670 requirements.

Comprehensive Self-Checking: The A6220 (9199-00009) continuously monitors hardware health, power supply stability, sensor cable continuity, and internal module temperature.
Compact Integration: Replacing legacy 6U hardware, the A6220 uses a single-slot 3U design to increase rack density while maintaining superior signal accuracy.
Deterministic Protection: Real-time eccentricity data ensures that rotor instability is flagged immediately, allowing for automated trip logic or manual intervention during sensitive thermal expansion phases.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
