Features:
- ABB article 3BSE050199R1 defines the redundant PM866 package with two processor units plus the documented TK850 CEX-bus and TK851 RCU-link interconnection cables.
- Each PM866 uses a 133 MHz MPC866 processor with 64 MB RAM; processor resources remain separate even though the pair provides controller availability.
- The documented maximum redundancy switchover is 10 ms, which depends on a matched CPU pair, correct link hardware, compatible firmware and an approved project configuration.
PM866K02 3BSE050199R1 is the redundant ABB AC 800M processor package based on two PM866 CPU units. ABB catalog information identifies the K02 scope as two PM866K01 processor packages with TK850 CEX-bus and TK851 RCU-link cables, while the individual processor packages include their baseplates, terminators and memory-backup batteries. Each MPC866 processor operates at 133 MHz with 64 MB RAM; those resources belong to each CPU and are not combined into one larger memory pool. PM866 supports CPU redundancy with a documented maximum switchover of 10 ms. The controller communicates through the established Control Network and coordinates CEX-bus interfaces and the permitted ModuleBus I/O arrangement. Both processors must have compatible hardware and firmware, and their project, partner status, links and terminations must be verified together. PM866AK02 3BSE081637R1 is the later redundant package, subject to formal migration review.
ABB System 800xA and Compact Products 800 catalogs. Values apply to the PM866 processors and the 3BSE050199R1 redundant package.
The ABB PM866K02 3BSE050199R1 is supported by Moore Automated for exact-item replacement and spare-part enquiries.

3BSE050199R1 covers two PM866 processor packages with TK850 and TK851 link cables. Confirm both CPUs, baseplates, terminators and batteries instead of treating a single PM866K01 as the complete K02 order.
Record the hardware and firmware marking of both PM866 units and verify partner synchronization, controller identity and project revision before restoring a redundant application.
TK850 provides the documented CEX-bus connection and TK851 the RCU link for the paired package. Inspect cable references, terminations and the permitted redundant ModuleBus topology before startup.
