Emerson identifies the A6824R as a 4 TE ModBus and Rack Interface Module with optional redundancy for AMS 6500 systems. The card occupies one slot in the IMR6500-series 19-inch rack and provides ModBus RTU and ModBus TCP/IP communication.
Supply Chain & Technical Deep Dive
When an AMS 6500 communication card fails, the replacement problem is often mechanical as well as electrical. The A6824R is specifically the 4 TE version intended for the IMR6500 rack, while the A6824 uses a wider 6 TE format for the IMR6000 series. That distinction matters during urgent maintenance because a visually similar interface card can still be the wrong rack format. The A6824R reads parameters from AMS 6500 modules and exposes machinery data through ModBus TCP/IP and ModBus RTU. Emerson lists speed, vibration components, gap value, alarm state, channel status, and phase among the available data types.
For TCO, the main consideration is retaining an existing AMS 6500 installation instead of introducing a larger system change for a single communication failure. The A6824R uses a maximum of 5 W and follows a 3U Eurocard format measuring 19.98 mm wide, 128.4 mm high, and 160 mm long. Net weight is approximately 320 g, with gross weight around 450 g including standard packaging. Operating temperature is specified at 0 to 65°C, with 5 to 95% non-condensing relative humidity. ModBus RTU is specified at 19.2 kbaud with 8 data bits, even parity, and one stop bit; the Ethernet interface uses an RJ45 socket with 10BaseT.
Migration, Compatibility & Field Traps
Replacement Matrix
| Replacement Path | Assessment | Engineering Requirement |
|---|---|---|
| Drop-in Replacement | Applicable for like-for-like A6824R replacement | Verify IMR6500 rack type, slot position, connectors, and installed system configuration |
| Software Compatible | Generally applicable within the same AMS 6500 architecture | Verify ModBus parameters, IP settings, module mapping, and redundancy configuration before commissioning |
| Hardware Modification | Normally not required for same-model replacement | Do not substitute the wider A6824 without confirming the rack format |
Field Traps — Watch Out
- Rack width mismatch: Emerson specifies at 4 TE for the IMR6500 series. The A6824 is 6 TE and intended for the IMR6000 series. Confirm the chassis before releasing a replacement card.
- Communication parameter mismatch: Check the installed ModBus RTU settings before startup. Emerson specifies 19.2 kbaud, 8 data bits, even parity, and one stop bit. The documented default IP address is 192.168.255.1 with a 255.255.255.0 subnet mask.
- Redundancy configuration: supports optional redundancy. Existing redundant communications should be documented before card removal so the replacement is commissioned with the intended architecture.
- ESD handling: Use an ESD-controlled work area and avoid contact with exposed PCB circuitry and connector contacts.

Quality Assurance & Testing SOP
- OEM anti-counterfeit visual inspection: Verify Emerson identification markings, model designation, 9199-00098-13 purchasing identifier where present, PCB markings, connector condition, fasteners, card handle, and serial traceability.
- Mechanical inspection: Check the Eurocard body, guide edges, front plate, connector contacts, mounting hardware, corrosion, contamination, overheating marks, and evidence of prior unauthorized repair.
- Power-on self-test (POST) checking for ERR/RUN LEDs: This specific interface card is documented with a green Power Supply OK LED rather than a generic ERR/RUN LED pair. Verify correct startup behavior and stable power indication.
- ModBus RTU functional test: Connect the module to a controlled serial test environment and verify 19.2 kbaud, 8 data bits, even parity, and one stop bit.
- ModBus TCP/IP functional test: Establish Ethernet communication through the RJ45 interface and verify expected addressing, response, and data exchange.
- I/O load testing: For this communication-focused module, perform interface-load and communications stress checks rather than analog I/O simulation. Verify stable RS485 and Ethernet communication under representative polling conditions.
- Data integrity test: Confirm representative AMS 6500 parameters can be read correctly, including speed, vibration, gap, alarm state, channel OK status, and phase where configured.
- Redundancy verification: For redundant applications, test the configured communication path and confirm expected behavior after removal or interruption of one path.
- Configuration verification: Record communication parameters and configuration information before shipment to support controlled field commissioning.
- Final inspection record: Capture serial number, inspection results, communication-test results, physical condition, and pre-shipment photographs.
Procurement-Driven FAQ
Is the Emerson 9199-00098-13 genuinely in stock and what is the cutoff for overnight shipping?
Physical inventory should be confirmed against the actual unit before purchase order release. Dispatch timing depends on inspection status, order cutoff, carrier service, customs clearance, and destination.
How do you guarantee the condition of an obsolete or surplus ?
Each unit should be evaluated individually rather than relying only on catalog status. The inspection process covers OEM identification, mechanical condition, controlled power-up, ModBus RTU testing, ModBus TCP/IP testing, communication integrity, and final photographic records.
What are the warranty terms and return policies for defective units?
The exact warranty duration and return conditions should be stated on the quotation and commercial documents for the supplied unit. A defect claim should reference the shipped unit’s serial number and inspection record.
Are there any firmware compatibility issues my engineers should warn about?
The engineering team should verify the installed configuration before commissioning. Published documentation identifies configuration and communication parameters as key setup points, while current Emerson material treats the classic protection-card family as legacy equipment.
Is the interchangeable with the A6824?
They should not be treated as unrestricted substitutes. Emerson specifies the A6824 at 6 TE for IMR6000-series racks and the at 4 TE for IMR6500-series racks, with redundancy available on the . Mechanical rack compatibility must be confirmed first.
