Emerson A6500‑SR Standard System Rack
Product Brand & Model Title
Official Product Name: A6500‑SR Standard System Rack Brand: Emerson / EPRO Model No: A6500‑SR Product Grade: 19‑inch 3U standard rack for AMS 6500 ATG API‑670 machinery‑protection system; available as new‑stock and spare‑part supplyEmerson
General Product Overview
The A6500‑SR is a 19‑inch 3RU standard system rack for Emerson AMS 6500 ATG machinery‑protection platform. It provides backplane bus, power distribution and card slots for measurement cards, relay logic card and communication cards. It supports hot‑swap for all plug‑in modules without powering down the whole rack. Backplane integrates spring‑loaded press‑in terminals and D‑Sub connectors for raw sensor signals, key‑phase and binary input signals. Multiple A6500‑SR racks can be cascaded to expand measurement channels. Widely used for steam turbines, gas turbines, compressors and other critical rotating‑equipment protection complying with API‑670 standard。
