Product Overview
In ABB’s System 800xA and AC 800M control systems, the UAC383AE01 (3BSE014666R1. which is actually the part number for CI541V1; the correct part number here is 3BSE041677R1) is a powerful main CPU module, belonging to the high-performance controllers in the AC 800M series.
This CPU module features a modular, DIN rail-mounted design and can be directly inserted into the AC 800M controller rack. Its core value lies in combining the deterministic control capabilities of a PLC with modern IT communication standards, supporting seamless connectivity from lower-level fieldbuses (such as PROFIBUS, Modbus RTU) to higher-level enterprise networks (Ethernet/IP, OPC UA). Typical application scenarios include:
As a local controller for DCS systems
Driving large motor control centers (MCC)
Implementing substation automation (supporting IEC 61850 GOOSE/SMV)
Building redundant safety control systems (paired with UAC384AE01)

Main Features and Advantages
* High-reliability architecture: Supports 1:1 redundancy configuration, primary and backup CPUs are synchronized via high-speed fiber optic cable, switching time < 100 ms, meeting the needs of continuous process control.
* Open communication capabilities: Dual Ethernet ports support independent network partitioning (e.g., control network + information network), built-in web server for remote status viewing. * **Powerful Programming Environment:** Fully compatible with IEC 61131-3’s five programming languages (LD, FBD, ST, SFC, IL), and supports C/C++ function block extensions.
* **System-Level Diagnostics:** Real-time monitoring of CPU load, memory usage, and communication errors, with event logs generated via Control Builder M or the 800xA system.
* **Long Lifecycle Support:** As one of the main CPUs for the AC 800M, ABB guarantees long-term supply and software compatibility.
**Typical Application Industries**
Power and Energy: DCS control for thermal/hydroelectric power plants, substation automation
Oil and Gas: Offshore platform ESD systems, pipeline SCADA
Chemical and Pharmaceutical: Reactor batch control, CIP/SIP process management
Water and Environmental Protection: Distributed control for large wastewater treatment plants, pump station group control
Metallurgy and Mining: Rolling mill drive control, mine hoisting systems
**Installation and Configuration Recommendations**
Rack Compatibility: Must be installed in a dedicated AC 800M controller rack (e.g., TK811V015), not compatible with S800 I/O racks.
Redundancy Configuration: For redundancy, two UAC383AE01 units, a redundant backplane (e.g., TK811V015-R), and synchronization fiber optic patch cables are required.
Firmware Version: Before initial power-on, it is recommended to check and upgrade to the latest stable firmware via Control Builder M to ensure compatibility.
IP Address Setting: Ethernet IP can be configured via the front panel DIP switches or software to avoid conflicts with the existing network.
Battery Maintenance: If using battery-backed RAM, regularly check the battery voltage (typically 3–5 years lifespan) to prevent program loss.
**Lifecycle and Procurement Recommendations**
As of 2026. the ABB UAC383AE01 (3BSE041677R1) remains in “Active” status and is one of the main CPUs for the AC 800M platform.
New Projects: ABB still recommends it for medium-scale control tasks; for higher performance requirements, consider the PM866 or AC 800M eCo series. Spare Parts Strategy: For critical systems in operation, it is recommended to stock at least one redundant CPU (2 units), as a CPU failure will cause the entire station to shut down.
Anti-counterfeiting Notice: Genuine products have clear labels, verifiable serial numbers, and no signs of secondary welding on the casing. Beware of low-priced refurbished parts.
Shenzhen Changxin promises: All ABB UAC383AE01 (3BSE041677R1) supplied are brand new genuine ABB original products, with official procurement channel certification. Each module undergoes power-on self-test, Ethernet communication testing, program download verification, and appearance quality inspection, and comes with a 12-month warranty and Control Builder M configuration assistance to ensure your control system runs stably and efficiently.
