ABB PM891K01 3BSE053241R1

  1. Product NameABB PM891K01 3BSE053241R1 High-end Redundant Processor Unit (for AC800M Series, ABB Ability System 800xA)
  2. Product DescriptionThe ABB PM891K01 3BSE053241R1 is a high-performance processor unit that belongs to the ABB AC800M controller series and serves as a core computing component of the ABB Ability System 800xA distributed control system (DCS). It is specially developed to address key pain points in high-end process control, such as single-point failure risks in critical scenarios, operational bottlenecks in complex control strategies, and insufficient real-time performance in multi-system collaboration.
Equipped with a powerful industrial-grade processor and ECC error-correcting memory, the module can achieve a control cycle as low as 1ms, smoothly running complex control strategies like cascade control and model predictive control. It adopts a 1:1 dual-machine hot standby redundant architecture. When the main controller malfunctions, it can switch to the standby unit seamlessly within 100ms, meeting the IEC 61508 SIL 3 safety requirements. Moreover, it supports seamless integration with various I/O modules and multiple industrial communication protocols, facilitating connection with on-site devices and upper-level monitoring systems. It is widely used in key industrial fields such as petrochemicals, supercritical power plants, and coal chemical industry, providing stable and reliable control support for uninterrupted production processes.
