Description

Emerson A6500‑RC System Relay Card (16‑Channel Relay Output Module)

Product Brand & Model Title

Official Product Name: A6500‑RC System Relay Card (16‑Channel Relay Output Module) Brand: Emerson / EPRO Model No: A6500‑RC Product Grade: Programmable relay logic card for AMS 6500 ATG machinery protection system; API‑670 compliant, available as new‑stock and spare‑part supplyEmerson

General Product Overview

The A6500‑RC is a microprocessor‑controlled plug‑in relay card for the AMS 6500 ATG machinery protection rack system. It receives alarm, alert and OK status signals from all measurement boards via rack backplane, supports user‑configurable Boolean logic, logic gating and time‑delay functions, and drives 16 independent SPDT relay outputs for interlock, trip and alarm actions. It implements complex machine‑protection logic without external PLC. Widely used for steam turbines, gas turbines, compressors and hydro‑turbine protection conforming to API‑670 standardEmerson.

Core Product Features

1. 16‑channel SPDT relay outputs: Provides hard‑wired trip / alarm contact outputs for rotating‑machinery protection.
2. Rich internal logic‑input resources: 66 logic signals read from all measurement cards via rack backplane, no extra field‑wiring required for alarm status acquisition.
3. On‑board programmable Boolean logic: Realizes complex voting logic, AND‑OR combination and time‑delay functions inside the card, reduces PLC dependency.
4. API‑670 compliant turbine‑protection solution: Designed for critical rotating‑equipment protection in power‑plant and oil‑gas sites.
5. Redundant 24 VDC power‑supply input: Improves power‑supply reliability for protection‑loop application.
6. Front‑panel LED channel indication: Direct visual status check for each relay output for quick site troubleshooting.
7. Software‑based graphical configuration: Parameter setup and logic programming via AMS 6500 engineering software with password protection.
8. Hot‑swap support: Permits live card replacement in ‑SR rack without system shutdown.
