PM858K02 ABB Redundant Processor Unit

Product Description

The ABB PM858K02 (3BSE082896R1) is a redundant processor unit designed for ABB AC 800M controller systems. It uses an MPC866 processor to execute application programs, control tasks, and function diagrams. The controller supports redundant operation with a maximum switchover time of 10 ms, allowing a standby processor to take over control when the active processor becomes unavailable. It also supports application cycle times down to 1 ms.

Key Features

• Redundant processor configuration with a maximum switchover time of 10 ms.
• MPC866 processor with 16 MB of memory.
• Application RAM of 7.147 MB.
• Supports up to 32 applications and 32 controller tasks.
• Supports up to 64 programs and 128 diagrams per application.
• Application program cycle times down to 1 ms.
• 4 MB Flash PROM for firmware storage.
• Redundant power supply status input.
• Built-in 3.6 V lithium backup battery.

Technical Specifications

Redundant Processing and Application Capacity

The PM858K02 supports redundant processor operation. In this configuration, the controller can transfer control to the standby processor if the active processor fails. The specified switchover time is a maximum of 10 ms. Therefore, this parameter is particularly relevant when evaluating controller redundancy and process continuity requirements.

Furthermore, the controller supports up to 32 applications, with each application accommodating up to 64 programs and 128 diagrams. It can execute up to 32 controller tasks and supports 32 different cycle times. Application programs can run with cycle times as short as 1 ms, depending on the application configuration.

Processor and Memory Resources

The MPC866 processor operates at 33 MHz and delivers a specified performance of 0.36 ms per 1000 Boolean operations. The unit provides 16 MB of memory, including 7.147 MB available for application use. In addition, its 4 MB Flash PROM stores firmware.

These specifications help engineers evaluate processing capacity and available memory when planning controller applications. Actual application capacity depends on program structure, task configuration, and resource allocation.

Power Supply and Physical Characteristics

The PM858K02 operates from a 24 V DC supply within a specified range of 19.2-30 V DC. Its typical current consumption is 210 mA, increasing to a maximum of 360 mA. Power dissipation is 5.1 W under typical conditions and 8.6 W at maximum.

The processor also includes a redundant power supply status input and a built-in 3.6 V lithium backup battery. Meanwhile, its physical dimensions and weight are relevant when checking cabinet space, mounting arrangements, and handling requirements.
