ABB PM862K02 Redundant Processor Unit

Description

The ABB PM862K02 Redundant Processor Unit is a high-performance component of the AC800M series, engineered for industrial automation systems requiring maximum reliability. Designed for use in sectors including chemical, oil and gas, power generation, and manufacturing, it features comprehensive redundant architecture to eliminate downtime from single-point failures. Key redundant capabilities include dual CPU operation with automatic master-slave switching, full system redundancy covering the CEX-Bus, communication interfaces, and S800 I/O modules, and support for redundant power input, ensuring uninterrupted system operation even if one CPU or critical component fails.

Equipped with an industrial-grade MPC866 CPU running at 67MHz, it delivers fast processing speeds, completing 1000 boolean operations in just 0.18 milliseconds. Its hardware configuration includes 32MB RAM for application storage and 4MB flash PROM for firmware storage, supporting complex control logic. The unit offers flexible connectivity with two RJ45 Ethernet ports compliant with IEEE 802.3 (10Mbit/s), two RJ45 serial ports (COM3 with RS-232C and modem control signals, COM4 as an isolated port for configuration tools), and supports fieldbus module expansion for enhanced I/O signal processing. With a modular design for easy installation and maintenance, it measures 119mm (4.7 inches) wide, 186mm (7.3 inches) high, 135mm (5.3 inches) deep, and weighs 2900g (6.4 lbs) including its base.
