Product Overview
A6210 is dual‑channel displacement monitor card for Emerson AMS 6500 machinery protection system. It receives signals from eddy‑current proximity probes, measures shaft thrust position, turbine differential expansion and valve rod‑drop position. Each channel supports alert / danger alarm thresholds, sensor fault diagnosis. Provides 4‑20 mA analog outputs to DCS/PLC. Multiple working modes: dual independent, tandem, min/max selection.
Important notes:
- Cannot work standalone; must install inside AMS 6500 rack, match with compatible proximity probe and driver.
- It measures position/displacement; not for vibration measurement (vibration uses A6220 module).
Application Scenarios
- Steam‑turbine / gas‑turbine TSI cabinet: Thrust position monitoring, turbine differential expansion supervision.
- Turbo‑generator power‑plant machinery‑protection racks: Rod‑drop monitoring for steam valve actuators.
- Centrifugal‑compressor critical position monitoring.
- Oil‑gas rotating‑equipment condition‑protection system.
- Retrofit & spare‑part replacement for existing AMS 6500 installations.
