ABB’s product record identifies 3BSE001449R1 as a System Status Collector and classifies it as a communication module within the AC 400 platform. ABB also lists the module as being used with AC450, AC450RMC and AC460 controller configurations.
Product Introduction
The ABB 3BSE001449R1 is a System Status Collector used in legacy ABB Advant Master controller architectures. Unlike an analog or digital I/O module, the ABB 3BSE001449R1 deals with controller-level status information rather than process signals. It belongs to the AC 400 communication-module family and is documented for Advant Controller 450, AC450RMC and systems.
The ABB 3BSE001449R1 is installed as part of the controller subrack architecture and is intended to collect system-status information for use by the controller system. ABB’s spare-parts documentation lists the exact article number under both and parts, confirming that this is a system-level component rather than a generic communication interface that can be substituted across ABB platforms.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
A status-collection module can be easy to overlook during DCS troubleshooting because it is not directly connected to conventional process I/O. That can be misleading. A failure or incorrect replacement of a controller-level communication/status module may produce system diagnostics or controller-status problems even though the field I/O modules themselves continue to operate normally.
For the 3BSE001449R1, the first question should therefore be whether the installed controller is actually an /AC450RMC or system. ABB’s product documentation does not identify this module as an AC800M, S800 or Advant 800xA controller component.
Typical Applications
- Advant Controller maintenance — replacement of failed system-status collection hardware.
- DCS maintenance — maintaining legacy MOD 300-based controller installations.
- AC450RMC systems — supporting controller configurations where the is included in the communication architecture.
- Legacy DCS cabinet refurbishment — retaining original controller hardware during long-term plant operation or migration planning.
ABB’s 2025 spare-parts document specifically lists 3BSE001449R1 / in both the and parts sections.
Technical Pitfalls to Avoid
1. Do not classify as a conventional process I/O module.
The ABB designation is System Status Collector, and ABB categorizes it as a communication module. It should not be specified as an analog input, digital output, relay or universal I/O card.
2. Verify the controller family before ordering.
The strongest ABB documentation associates with , and . Do not assume that a physically similar module from another Advant generation is interchangeable.
3. Do not confuse with the TC5xx modem family.
ABB’s spare-parts list contains TC512V1, TC513V1, TC516, , TC562, TC570, TC625 and TC630. These are different products with different functions. TC512V1 and TC516, for example, are modem products, while is specifically the System Status Collector.
4. Be careful with unsupported electrical specifications.
Some secondary listings assign values such as 220 VAC operating voltage or 30 kHz output frequency to . Those figures are not supported by ABB’s product record. For procurement and engineering documentation, they should not be treated as specifications for this module.
5. Check physical dimensions against the installed cabinet documentation.
ABB specifies approximately 279 mm depth, 153 mm width and 27 mm height, with a net weight of 0.29 kg. These values differ from several inconsistent third-party listings, so ABB’s product record should take priority when preparing cabinet documentation.
6. Do not assume the module is a current-generation ABB product.
ABB announced that the Advant Master product line entered its Limited life-cycle phase on July 1, 2025, with new modules no longer manufactured and parts services continuing on a best-practical-effort basis. This makes advance spare planning particularly important for plants that still depend on / hardware.
7. Inspect the complete assembly identification.
For an existing brownfield installation, compare the label, article number, controller type, subrack position and adjacent communication modules. A visually similar ABB communication card should not be treated as a direct substitute without system documentation.

Procurement Note
For ABB 3BSE001449R1, the critical procurement checks are the exact article number, controller family, installed subrack configuration and hardware condition. Do not substitute another TC5xx communication module based only on physical appearance or naming.
ABB’s current product record confirms the exact designation and identifies the module as a System Status Collector, while ABB’s 2025 spare-parts notice places within the limited-life Advant Master/ spare-parts program. For plants still operating or systems, holding a tested spare is considerably more practical than discovering a shortage after a controller-level fault occurs.
