ABB’s spare-parts documentation specifically identifies 3BSE003528R1 as — Dummy Module for Submodule and lists it among AC460 spare parts. The same document distinguishes RB510, RB530 and RB540 as different dummy-module applications.
Published product data gives the physical dimensions as approximately 30 × 95 × 20 mm and net weight as 0.028 kg. These are useful identification values, but the actual carrier and slot should still be checked before substitution on an installed system.
Product Introduction
The ABB 3BSE003528R1 is a passive dummy module designed to occupy an unused submodule position in ABB Advant Master control hardware. It does not process field signals, execute control logic, provide relay outputs, or perform communication. Its purpose is to maintain the intended physical configuration of the submodule carrier when an active module is not installed.
For engineers maintaining older ABB Advant Master / AC460 installations, the ABB 3BSE003528R1 can be important despite having no electrical processing function. Maintaining the original slot configuration can simplify cabinet restoration and prevent confusion during future maintenance, particularly when the plant documentation still references the original submodule arrangement.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
A common issue with legacy DCS cabinets is that a missing filler gets treated as an opportunity to install whatever spare module happens to fit physically. That is the wrong approach here. is specifically a dummy module for a submodule position, and ABB’s parts documentation distinguishes it from other filler modules used elsewhere in the Advant architecture.
Typical Applications
- Advant Master AC460 maintenance — restoring the original configuration of legacy controller hardware.
- Advant OCS cabinet refurbishment — replacing missing or damaged slot fillers.
- Legacy DCS spare-parts management — retaining the correct mechanical spare for an unused submodule position.
- Plant migration preparation — preserving existing cabinet configurations while active control hardware is being evaluated for replacement.
Technical Pitfalls to Avoid
1. Do not identify as an active I/O module.
ABB’s own description is unambiguous: is a dummy module for a submodule slot. There are no analog channels, digital channels, relay outputs or communication functions to configure.
2. Do not confuse with RB510.
ABB lists RB510 3BSE003527R1 as a dummy module for a submodule carrier, while 3BSE003528R1 is the dummy module for the submodule position itself. The similar naming does not establish interchangeability.
3. RB530 and RB540 have different applications.
ABB identifies RB530 3BSE003529R1 as a dummy module for a single S500 plug-in unit and RB540 3BSE004693R1 for a double S500 plug-in unit. Do not substitute one merely because the parts look similar.
4. Ignore listings that describe 3BSE003528R1 as a relay-output card.
Some secondary databases incorrectly classify as a relay-output/filler module and even attach output-current specifications to it. That information conflicts directly with ABB’s identification of the exact article number as a dummy module.
5. Verify the actual carrier position.
On a brownfield Advant installation, check the existing rack, carrier designation, neighboring modules and cabinet drawings before ordering. The part number should be matched to the intended mechanical position rather than selected from a generic “dummy module” category.
6. Do not assign electrical specifications to the part.
Voltage, current, signal type, protocol and I/O-channel specifications are not applicable to . Any listing providing relay-channel or analog-I/O specifications for this exact article number should be treated cautiously.

Procurement Note
For ABB 3BSE003528R1, the principal procurement risk is part identification, not electrical compatibility. Confirm the complete designation / 3BSE003528R1 and the intended submodule-slot position before accepting an alternative.
For long-life Advant Master installations, keeping the original filler module available can be worthwhile during cabinet refurbishment. ABB itself lists as an spare under its “While Supplies Last” documentation, which indicates that this is a legacy-maintenance item rather than a current-generation automation module.
