The ABB CI546 (3BSE012545R1) acts as a high-performance communication interface module for the Advant Controller 400 (AC 400) and Advant Master DCS platforms. This module facilitates critical data exchange between the central controller and various field devices or peer-to-peer controller networks. By supporting the MasterBus 300 protocol, the CI546 enables seamless integration and real-time synchronization across the plant’s distributed architecture. We supply this module as 100% Brand New and Original, ensuring high-availability communication for legacy and modern process control environments.

The CI546 module solves communication bottlenecks and protects system integrity through specialized hardware logic and optimized data handling.
Deterministic MasterBus 300 Connectivity: The CI546 manages high-speed data packets via the MasterBus 300 protocol. This ensures that time-critical process data from turbine controllers or compressor stations reaches the central DCS without variable latency.
Superior Galvanic Protection: Internal galvanic isolation barriers shield the Advant Controller 400 backplane from field-side electrical surges and noise. This prevents local electrical faults from propagating into the core control logic, a necessity in high-interference power generation sites.
Low-Profile Modular Architecture: With a width of only 25 mm and a lightweight 0.17 kg frame, the module optimizes rack density. This compact footprint allows engineers to add communication channels in existing cabinets without requiring extensive physical restructuring.
Advanced Synchronization Logic: The CI546 maintains strict synchronization between the controller and I/O tiers. This prevents data skew and ensures that interlocking safety sequences execute with microsecond precision based on the most current field state.
Is the CI546 3BSE012545R1 compatible with the Advant Master DCS?
Yes. The CI546 specifically supports both the Advant Controller 400 series and the broader Advant Master DCS environment, primarily utilizing the MasterBus 300 network standard.
What are the mounting requirements for this module?
The CI546 slides into standard sub-racks designed for the Advant Controller 400. Ensure you verify the SCIP ID (a7cc9b1e-4d75-4756-8f86-7821a86dbb3a) for compliance tracking within European industrial installations.
Does this module require external cooling?
The module operates reliably between –20°C and +60°C. While it does not require dedicated fans, you must maintain proper cabinet airflow to prevent heat buildup, especially when mounting multiple communication boards in a single rack.
How can I confirm this is a Brand New unit?
Every unit we ship is 100% Brand New and Original. The module carries the genuine 3BSE012545R1 product ID and arrives in its original factory state, backed by our commitment to industrial-grade quality and authentic ABB hardware.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
