Product Introduction (Rotation Engine)
A vibration or displacement monitor only becomes protective when its alarm state reliably reaches the trip circuit. The EMERSON A6500-RC is a 16-channel relay output module for the AMS 6500 ATG machinery protection system, designed to convert channel OK/alert/danger signals into actionable relay outputs for alarms, annunciators, and turbine/compressor trip logic. It accepts up to 66 digital inputs from measurement modules, applies configurable Boolean logic and time delays, and drives 16 SPDT relay outputs.
For reliability and procurement teams, this module is a targeted spare for existing AMS 6500 ATG installations. Because it matches the relay function already configured in the rack, it helps restore protection continuity faster during corrective maintenance. A factory-sealed surplus unit also reduces the risk of prior field-wiring faults, aged relay contacts, moisture ingress, or unknown service history.

Key Selling Points & Differentiators
- 16 SPDT relay outputs for alarms, annunciators, and trip circuits in API 670 protection systems.
- 66 digital inputs accept OK/alert/danger status from AMS 6500 ATG measurement modules.
- Configurable Boolean logic with 0–30 s delay reduces nuisance trips during transient conditions.
- Hot-swappable 3U, 2-slot module for AMS 6500 ATG / A6500-SR rack installations.
- Factory-sealed surplus stock reduces risk of aged relay contacts, prior field faults, or moisture damage.
- Not recommended as a replacement for vibration, displacement, overspeed, or processor modules; this is a relay output module, not a measurement or controller card.
Quality Transparency SOP (DYNAMIC GENERATION)
For surplus AMS 6500 A6500-RC relay output modules, inspection focuses on relay health, logic input integrity, and output behavior:
- Visual QA: Inspect front panel, connectors, terminals, relay indicators, and housing for corrosion, impact damage, or bent pins.
- Anti-static handling: Seal in ESD-safe packaging with humidity indicators before shipment.
- Rack registration test: Verify the module registers correctly when seated in an AMS 6500 ATG / A6500-SR rack.
- Power-up and diagnostics check: Confirm expected power behavior and module diagnostic status.
- Relay output verification: Simulate digital input states and verify relay actuation, contact timing, and SPDT behavior using a multimeter or relay tester where safe.
Technical Risk Avoidance (DYNAMIC GENERATION)
❗ Confirm system family. The EMERSON A6500-RC belongs to the AMS 6500 / AMS 6500 ATG machinery protection family. It is not a CSI 6500 vibration/position module and not a standalone relay card.
❗ Verify rack compatibility. This module is specified for the A6500-SR rack and occupies two slot positions. Installing it in an incompatible chassis can prevent registration or damage the backplane.
❗ Validate logic configuration before commissioning. Boolean logic, time delays, and relay assignments must match the existing protection philosophy. Incorrect logic can cause nuisance trips or missed protection.
❗ Check relay load ratings. Relay contacts are rated up to 32 V DC / 48 V AC at 2 A. Do not exceed rated load, and verify coil suppression on inductive loads.
Buyer’s FAQ
Is this a genuine Emerson module?
Yes. The EMERSON A6500-RC is an original AMS 6500 ATG 16-channel relay output module. We supply factory-sealed surplus stock when available.
What condition is the module in?
Units are sold as New Original / New Surplus unless otherwise stated. That means unused, factory-sealed inventory rather than field-removed or refurbished hardware.
Can I use it as a direct replacement?
If your existing AMS 6500 ATG installation uses an A6500-RC relay output module and the rack, logic configuration, and relay assignments match, this module should be a like-for-like replacement. Always confirm the nameplate and existing configuration first.
Does it work with CSI 6500?
No. The A6500-RC is part of the AMS 6500 / AMS 6500 ATG machinery protection system. It is not a CSI 6500 module.
How fast can you ship?
Stock availability determines lead time. For urgent machinery protection failures, request expedited shipping at checkout.
Do you offer a warranty?
Yes. Warranty terms are provided at checkout. For surplus protection components, a clear warranty window helps protect against DOA or hidden inventory damage.
