ABB Advant AC 800M
The ABB Advant AC 800M is a modular and scalable controller series designed to provide high-performance automation for industrial processes. As part of the ABB System 800xA architecture, the AC 800M is recognized for its versatility in handling diverse communication protocols and high-density I/O requirements. Even as certain modules reach their "Limited" or "Obsolete" lifecycle stages, maintaining these systems is essential for operational continuity.
Moore Automation specializes in sourcing and supplying discontinued and hard-to-find ABB AC 800M components. We provide a reliable inventory of surplus and new-old-stock parts, helping plants avoid the high costs and risks associated with premature system-wide replacements.
1. Key Components and Inventory Categories
Our inventory covers the essential hardware required to maintain or expand your AC 800M distributed control system (DCS):
- Processor Modules (CPUs): Including the PM861, PM864, PM865, PM866, and the high-capacity PM891. These controllers support various memory configurations and redundancy for critical applications.
- Communication Interfaces (CI): Modules supporting multiple industrial protocols such as CI854/CI854A (PROFIBUS DP), CI867 (Modbus TCP), CI853 (RS-232C), and CI858 (DriveBus).
- S800 I/O System: A comprehensive range of rail-mounted modules, including digital inputs/outputs (DI810, DO810), analog modules (AI810, AO810), and their corresponding Terminal Units (TU).
- Infrastructure & Power: Critical hardware including SD822 and SD832 power supply units, TP830 baseplates, and BC810 bus interconnection units.
2. System Evolution: The Path to Modernization
The AC 800M serves as a technical bridge for legacy Advant OCS and MOD 300 systems transitioning toward System 800xA. This evolution allows for phased hardware updates rather than a complete "rip-and-replace" strategy.
| Evolution Aspect |
Legacy Status |
AC 800M Migration Path |
| Controller Level |
Older AC 410/450 or MOD 300 hardware |
Replace aging processors with AC 800M to increase logic capacity while retaining core logic. |
| I/O Integration |
S100 I/O Racks |
Utilize interfaces like the CI856 to allow AC 800M controllers to drive existing S100 I/O, protecting wiring investments. |
| Network |
Serial or proprietary MB300 bus |
Transition to Ethernet-based architectures via AC 800M for improved data throughput and 800xA integration. |
3. Quality Assurance and Support
- Technical Inspection: All AC 800M modules undergo professional visual inspection and power-on testing to ensure they meet original technical specifications.
- Immediate Fulfillment: We maintain an "Emergency Warehouse" model with ready-to-ship stock to minimize downtime caused by OEM lead times.
- 12-Month Warranty: Every part supplied by Moore Automation is backed by a full one-year warranty, covering repair or replacement.
Frequently Asked Questions (FAQs)
Q: Can PM866 and PM864 modules be configured for redundancy?
A: Yes. The AC 800M series supports CPU redundancy. This requires a pair of identical CPUs, a specific redundant baseplate, and the BC810 interconnection unit to ensure bumpless transfer in case of a failure.
Q: Does the S800 I/O system support Hot-Swapping?
A: Yes, when used with appropriate baseplates (such as the TP830), S800 I/O modules support "Run-and-Insert-Under-Power" (RIUP), allowing for the replacement of faulty modules without stopping the controller.
Q: How do I ensure a replacement PM866 is compatible with my existing software?
A: Compatibility is determined by the firmware version loaded onto the module. We can assist in verifying or matching the firmware to your specific Control Builder M version requirements.
Q: Are these parts new or refurbished?
A: We supply a mix of New-in-Box (NIB) and high-quality Surplus (refurbished) stock. All items retain their original serial numbers for traceability and technical verification.
