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 supplied AC 800M items receive a pre-shipment inspection. Functional testing is performed only where suitable equipment and procedures are available for the specific item. Confirm the inspection scope and known limitations in writing before ordering.
- Urgent dispatch options: Availability and timing are confirmed before order approval.
- 12-Month Warranty: Every supplied item includes a 12-month Moore Automated supplier warranty from shipment, subject to the Warranty Policy and its exclusions.
Frequently Asked Questions (FAQs)
What must be checked for an AC 800M redundant controller configuration?
Redundancy support and required components depend on the exact processor and system version. Check the approved CPU pair, firmware, RCU link and CEX-Bus arrangement in the applicable ABB manual. BC810 or BC820 requirements depend on the selected configuration; do not assume that one interconnection unit is mandatory for every redundant installation.
How should I verify whether an S800 I/O module can be replaced online?
Check the exact S800 I/O module, its module termination unit and the applicable ABB replacement procedure. TP830 is a processor baseplate and should not be used as a general example of an S800 I/O termination unit. Online replacement also requires review of the installed configuration and site approval by qualified personnel.
How do I ensure a replacement PM866 is compatible with my existing software?
Confirm the exact hardware revision, installed firmware and applicable Control Builder M and system requirements against ABB documentation. We can help review item identification, but final compatibility and commissioning approval remain with the customer’s qualified engineering team.
Are the AC800M parts you supply new or refurbished?
Moore Automated supplies new and unused AC800M parts, including new surplus. We do not sell used, dismantled or refurbished units. New surplus may have older packaging, date codes or revisions; the actual condition and required identifiers are confirmed in the quotation.
