ABB PXHK401 (3BSE011790R1) – High-Performance DCS Control Board | AC800M Platform
Engineering Background: The PXHK401 is a core control processing board designed for ABB’s AC800M Distributed Control System (DCS) platform — one of the most widely deployed process automation architectures in power generation, oil & gas, chemical, and pulp & paper industries. Part number 3BSE011790R1 is the ABB factory reference for this board revision.
Product Positioning: Engineered for mission-critical process control environments where signal integrity, deterministic scan cycles, and long-term platform continuity are non-negotiable. The PXHK401 serves as the communication and coordination backbone within AC800M controller racks, enabling seamless I/O expansion and fieldbus integration.

Proven Application Environments
- Power Generation: Turbine governor control, boiler management systems, and plant-wide DCS integration using AC800M controllers.
- Oil & Gas: Upstream/downstream process control, SCADA integration, and safety instrumented system (SIS) coordination.
- Chemical & Petrochemical: Continuous process control with high-cycle I/O scanning and redundant communication paths.
- Pulp & Paper: Multi-loop control, drive coordination, and quality control system integration.
- Water & Wastewater: SCADA-linked distributed control with remote I/O expansion via PROFIBUS-DP.
Engineering Advantages
- Platform Longevity: AC800M is an actively supported ABB platform with a long-term spare parts ecosystem — reducing obsolescence risk for plant operators.
- Deterministic Control: Fixed-cycle scan architecture ensures predictable response times critical for closed-loop process control.
- Hot-Swap Capability: Designed for online replacement in redundant AC800M configurations, minimizing planned downtime.
- Broad Fieldbus Support: Native PROFIBUS-DP and ModuleBus integration enables connection to hundreds of field devices without additional gateways.
- Compact Form Factor: Rack-integrated design maximizes cabinet density while maintaining full diagnostic accessibility.
System Architecture & Signal Flow
Within an AC800M rack, the PXHK401 interfaces directly with the PM8xx processor module via the internal ModuleBus backplane. It manages communication arbitration between the CPU, I/O modules (S800 series), and external fieldbus networks. Signal flow: Field Devices → S800 I/O → ModuleBus → PXHK401 → PM8xx CPU → Control Application (Control Builder M).
In redundant configurations, dual PXHK401 boards operate in active/standby mode with automatic bumpless transfer on fault detection, ensuring zero process interruption.

Technical FAQ
Q: Is the PXHK401 compatible with AC800F controllers?
A: The PXHK401 is primarily designed for the AC800M platform. Compatibility with AC800F depends on the specific firmware revision and rack configuration. Please contact our technical team to confirm compatibility for your application.
Q: Can this board be used in a redundant controller configuration?
A: Yes. The AC800M platform supports redundant controller pairs. The PXHK401 is compatible with redundant setups when paired with the appropriate PM8xx processor and redundancy module.
Q: What software is required to configure this module?
A: ABB Control Builder M (CBM) is the standard engineering tool for AC800M-based systems. The PXHK401 is recognized automatically within the CBM hardware configuration tree.
Q: Do you provide a test report or certificate of conformity?
A: Yes. A functional test report and certificate of conformity are available upon request for orders of 1 unit or more.
Q: What is the lead time for bulk orders?
A: Standard stock orders ship within 1–3 business days. For bulk quantities (>5 units), lead time is 5–15 business days depending on availability. Contact us for a firm commitment.
