Emerson A6410 (9199-00005) dual-channel expansion monitor for AMS6500, API670 compliant, monitors turbine case expansion and valve stem displacement.

Product Overview

• Part No: A6410, 9199-00005
• Brand: EMERSON / EPRO

• Category: Dual Channel Case Expansion & Valve Displacement Monitor Module A6410 (9199-00005) is a 3U plug-in module for Emerson AMS6500 Machinery Health Monitor, complying with API 670. It works with 9350 series inductive displacement sensors to measure turbine casing thermal expansion and valve stem displacement. Two independent channels support absolute and relative displacement measurement. Users can set configurable Alert and Danger thresholds with adjustable delay and hysteresis. It provides buffered sensor signals, 4–20mA / 0–10VDC analog outputs and relay alarm contacts to connect with DCS systems. Front panel LEDs display channel operating status and fault alarms. Hot-swap function supports online replacement without interrupting rack protection logic. It is essential maintenance spare for steam turbines in power and petrochemical plants.
