ABB PM866K02 3BSE050199R1 AC 800M Redundant Processor Units

Description

The PM866K02 3BSE050199R1 is a redundant processor unit kit configured for the AC 800M control system platform, designed to deliver high availability and fault-tolerant process control. Equipped with a microprocessor operating at a clock frequency of 133 MHz and supported by 64 MB of RAM, this system component handles execution of complex control logic, diagnostics, and simultaneous communication tasks. The assembly natively interfaces with up to 12 S800 I/O units via its electrical ModuleBus and includes four onboard communication ports supporting dual Ethernet (CN1, CN2) and serial (COM3, COM4) connections. The packaged kit provides two PM866K01 processor units alongside a TK850 CEX-bus expansion cable and a TK851 RCU-Link cable, facilitating precise module synchronization and communication bus expansion within the 800xA and Compact Product Suite infrastructures.

Features

• Microprocessor execution driven by an MPC866 processor running at a clock frequency of 133 MHz.
• Volatile memory management utilizing 64 MB SDRAM paired with 4 MB flash PROM for firmware residency.
• Comprehensive onboard interface allocation featuring dual Ethernet channels and dedicated serial links with modem support.
• Direct local I/O handling supporting up to 12 S800 I/O units connected to the electrical ModuleBus.
• Dedicated Redundancy Control Link enabling structural synchronization between parallel processor units.
• Integrated Compact Flash interface supporting runtime application loading and cold retain data storage operations.
• Built-in internal 5ms power reservoir ensuring ordered and controlled CPU power-down cycles during supply disruptions.

Applications

• Distributed Control Systems (DCS) requiring process redundancy within 800xA automation setups.
• Critical path control infrastructure across manufacturing, power generation, and process refining fields.
• High-availability operations utilizing Compact Product Suite architectures and S800 remote I/O configurations.

Installation Guidelines

• Module Orientation: Mount the assembly horizontally along the DIN rail, ensuring the vertical height allows lock mechanism clearance.
• Redundant Coupling: Interconnect the twin processors using the included TK851 RCU-Link cable to initialize the synchronization channel.
• CEX-Bus Interfacing: Utilize the supplied TK850 expansion cable to attach additional communication modules along the side terminal paths.
• Wiring Configuration: Secure connections using the 4-pin screw terminal block, ensuring standard polarity match for L+ and L- paths.
• Status Monitoring Terminal: Wire supply monitoring relays to the SA and SB ports, observing logical threshold limits (High over 15 V, Low under 8 V).
• Thermal Management: Allow sufficient convective clearance within the IP20 enclosure to maintain operation within nominal thermal boundaries.
• Memory Preservation: Insert either an internal or external battery unit (SB821 or SB822) to retain runtime RAM definitions during complete power failures.
