Product Brand & Model Title
Official Product Name: A6500‑UM Universal Measurement Card Brand: Emerson / EPRO Model No: A6500‑UM Product Grade: API‑670 compliant dual‑channel universal monitoring card for AMS 6500 ATG machinery protection system; available as new‑stock and spare‑part supplyEmerson
A6500‑UM
General Product Overview
The A6500‑UM is a hot‑swappable 3U Eurocard measurement module for AMS 6500 ATG turbine‑protection rack system. It provides 2 independent sensor input channels, compatible with eddy‑current probes, piezoelectric accelerometers/velometers, seismic velocity sensors, LF low‑frequency vibration sensors, Hall‑effect speed sensors, and LVDT (with A6500‑LC adapter). It measures shaft relative vibration, casing vibration, thrust position, differential expansion, rotational speed and key‑phasor signals. It integrates DSP signal processing, PeakVue diagnostics, 5 digital inputs, 6 digital outputs and isolated 0/4‑20 mA analog outputs. Measurement data is transmitted via internal RS‑485 bus to A6500‑CC communication card for Modbus‑TCP / OPC‑UA upper‑system access. Widely used for steam‑turbine, gas‑turbine and centrifugal‑compressor protection conforming to API‑670 standard.
