ABB Advant OCS with AC 800M: High-Availability Control for Heavy Industry
The ABB Advant OCS featuring the AC 800M controller is the backbone of heavy industrial automation, particularly in mining, power, and large-scale manufacturing. Powered by high-performance processors like the PM866 and PM864, the AC 800M offers unmatched scalability and redundancy. Integrating seamlessly with S800 I/O and fieldbus communications (PROFIBUS via CI854), this system ensures continuous uptime in the most demanding environments.
As a global logistics expert for ABB, Siemens, and Honeywell, we bridge the gap for critical DCS and PLC spares. We maintain a steady inventory of original PM866, PM864, and PM861 controllers. Every module is 100% original new, ensuring your plant’s legacy systems remain operational with Immediate International Dispatch.

| Catalog Number | Module Type | System Function |
|---|---|---|
| PM866 / PM866K01 | Processor Unit (133MHz) | High-Speed Control Logic Execution |
| CI854-K01 / CI854A | PROFIBUS DP Interface | Communication with Field Devices |
| AI810 / DI810 | S800 Analog/Digital I/O | Signal Acquisition & Process Control |
| TB810 / TB820 | Module Termination Unit | Backplane Cluster Connection |
Optimized for 800xA Lifecycle Support
The AC 800M controller is a key part of the System 800xA ecosystem. We provide specific hardware support for ongoing plant maintenance:
Redundant Processor Setup:
Using dual PM866 units, we help you achieve the highest availability for mission-critical mining and energy processes, preventing costly unplanned shutdowns.
Legacy System Continuity:
We understand the long lifecycles of Advant OCS systems. Our supply chain ensures even older PM861 and CI854 revisions remain available for immediate replacement.
Fast Shipping to High-Latitude Projects: We specialize in logistics for industrial sites in remote regions, ensuring your ABB spares arrive with all necessary documentation and original seals.
