Product Introduction (Rotation Engine)
When vibration, position, and speed data stay locked inside the protection rack, operators cannot act on them fast enough. The EMERSON A6824 9199-00090 is the ModBus and rack interface module for the Emerson AMS 6500 / CSI 6500 machinery health platform. It reads parameters from all AMS 6500 monitoring modules in the rack and outputs them through ModBus TCP/IP and/or ModBus RTU serial communication.
This 3U, 1-slot module supports API 670-compliant machinery protection integration and can feed speed, vibration, gap values, alarm states, channel status, and phase data into DCS, SCADA, historians, or third-party analytics hosts. It also supports local graphical displays on the protection rack. For plants maintaining legacy Emerson/EPRO AMS 6500 systems, this interface module is useful for restoring rack-to-host communication, replacing a failed card, or standardizing spare parts across turbine and compressor trains.

Key Selling Points & Differentiators
- Direct replacement for AMS 6500 / CSI 6500 ModBus rack interface applications.
- Supports ModBus TCP/IP and ModBus RTU simultaneously for flexible DCS/SCADA integration.
- 3U, 1-slot design reduces rack footprint compared with legacy 6U cards.
- Hot-swappable and API 670-compliant for continuous protection operation.
- Factory-sealed surplus reduces DOA risk versus pulled used modules.
- Not recommended for AMS 6300 SIS overspeed racks, Ovation DCS I/O slots, DeltaV I/O slots, or non-AMS 6500 / CSI 6500 frames.
Quality Transparency SOP (DYNAMIC GENERATION)
- Visual inspection: Check front panel, RJ45, RS-485 connectors, LED indicators, PCB surface, corrosion, and factory seal integrity.
- Part verification: Confirm model A6824 9199-00090, revision, and module width against the packing list.
- Power-up test: Verify module boot, self-diagnostics, and LED status on a compatible AMS 6500 / CSI 6500 rack.
- Communication test: Verify ModBus TCP/IP connectivity via RJ45 and ModBus RTU via RS-485 with a calibrated ModBus tester or laptop.
- Rack data test: Confirm the module reads parameters from installed AMS 6500 monitoring modules.
- Final packing: Anti-static bag, moisture barrier, shock-safe boxing, and photo-documented QA.
Technical Risk Avoidance (DYNAMIC GENERATION)
❗ Do not install A6824 9199-00090 in an AMS 6300 SIS overspeed rack, Ovation DCS I/O, or DeltaV I/O. It belongs to the AMS 6500 / CSI 6500 machinery health platform.
❗ Confirm module width before ordering. A6824 is 6TE for IMR6000 racks, while A6824-R is 4TE for IMR6500 racks.
❗ Verify IP address, subnet mask, ModBus register map, baud rate, and parity before connecting to DCS/SCADA. Wrong settings can look like a hardware fault.
❗ If redundancy is required, confirm whether your rack supports A6824-R. The A6824 9199-00090 does not include a redundancy option.
Buyer’s FAQ
Is this a genuine OEM part?
Yes. This is an OEM Emerson AMS 6500 / CSI 6500 component supplied as new surplus / factory sealed. We do not rebrand or relabel third-party equivalents.
Is it new or refurbished?
Listed as New Original (New Surplus) / Factory Sealed unless otherwise stated. Any deviation in condition will be disclosed before shipment.
Can I use it as a direct replacement?
Yes, for AMS 6500 / CSI 6500 ModBus rack interface applications. Confirm your rack series (IMR6000 vs IMR6500), firmware, and communication settings first.
Does it support redundancy?
No. The A6824 9199-00090 is the non-redundant 6TE version. If you need redundant ModBus communication, the A6824-R variant should be used instead.
What warranty is included?
A 1-year functional warranty covers manufacturing defects and DOA failures. Damage from incorrect configuration, incompatible racks, improper installation, or firmware mismatch is not covered.
