Description
Alstom SRE232.1 029.228 675 Drive Control Module
Product Introduction
In a legacy drive or converter cabinet, the control board is often the component that cannot be treated as a generic spare. The Alstom SRE232.1 029.228 675 is identified in available industrial references as a Drive Control Module, specifically associated with Rev. 07.
For maintenance teams supporting older Alstom control equipment, the complete identification matters more than the SRE232.1 family name alone. Public listings also identify an SRE 232.1 with part number 029.223 833, demonstrating why part-number and revision matching should be completed before a legacy PLC, converter, or drive-control replacement is approved.

Detailed electrical specifications such as supply voltage, I/O architecture, communications, and environmental limits were not sufficiently documented in the sources reviewed, so they should not be treated as confirmed specifications.
Major Features / Advantages
Dedicated Drive-Control Function
The SRE232.1 is identified as a Drive Control Module rather than a general-purpose PLC I/O card. That distinction matters during troubleshooting because a drive-control board normally sits within a coordinated control architecture involving other processing, interface, feedback, and power-conversion assemblies. The available references consistently classify SRE 232.1 as a drive-control component.

Exact 029.228 675 Identification
For procurement, 029.228 675 should be recorded exactly as supplied, including punctuation and revision information. A matching SRE232.1 model name does not automatically establish interchangeability. Public references identify another SRE 232.1 as 029.223 833, which is a useful warning against purchasing by family designation alone.
Rev. 07 Traceability
The exact 029.228 675 listing identifies the unit as Rev. 07. For a legacy drive system, revision control can be significant because hardware changes, component substitutions, firmware dependencies, or interface revisions may not be obvious from the base model designation. The revision printed on the physical assembly should therefore be compared with the approved equipment documentation before installation.
Practical Value for Legacy Equipment
The SRE 232.1 family continues to appear in industrial automation spare-part references, including sources that specifically classify it as a Drive Control Module. That makes accurate identification useful when maintaining installed equipment for which the original engineering documentation is incomplete or difficult to obtain.
Better Procurement Control
A replacement request should contain the manufacturer, .1 model, 029.228 675 part number, Rev. 07, and photographs of the nameplate or PCB markings when possible. This gives the supplier enough information to distinguish the requested assembly from other SRE 232.1 variants. It also reduces the risk of receiving a visually similar board that belongs to another machine configuration.
Application Scenarios & Pain Points
The .1 is most relevant when maintaining an existing Alstom drive or converter control architecture where the original control hardware remains part of the installed system.
- Legacy drive maintenance: Used as an identified spare for equipment incorporating the SRE 232.1 drive-control architecture.
- Converter control troubleshooting: Appropriate for maintenance investigations where loss of drive-control functionality has been traced toward the control module.
- Planned shutdown replacement: Useful when an aging control board is being replaced during scheduled maintenance rather than after an unexpected drive trip.
- Legacy system refurbishment: Relevant when an older Alstom control cabinet must remain operational while other parts of the plant are being modernized.
The main field problem is not simply finding an .1. It is proving that the replacement is the same hardware configuration. The existence of multiple public SRE 232.1 part-number references makes that distinction particularly important.

Engineer’s Guide: Field Pitfalls to Avoid
1. Do not buy from “.1” alone
This is the most important point. The public record shows at least two different part-number references associated with SRE 232.1. Treat 029.228 675 as the controlling identification for this request.
2. Verify the revision marking
The requested assembly is identified as Rev. 07. Compare the PCB or nameplate marking with the replacement documentation before installing it.
3. Do not assume electrical compatibility
Public sources do not provide enough reliable information to establish the exact supply voltage, I/O arrangement, communication interfaces, or environmental limits for 029.228 675. Those values should come from the original Alstom equipment documentation or the board’s engineering documentation, not from a generic SRE 232.1 listing.
4. Check the complete drive architecture
A drive-control module is only one part of a larger control system. Before replacement, document the associated processor, converter interface, feedback circuits, power section, terminal assemblies, and configuration data where applicable.
5. Confirm actual inventory condition
Legacy automation hardware may be offered as unused, refurbished, repaired, or previously installed equipment. The product listing itself does not establish the physical condition of a particular unit. Inspect the actual board, labels, revision, connectors, and evidence of previous repair before accepting it as an installation-ready spare.
FAQ
Is Alstom .1 029.228 675 a drive control module?
Yes. Public industrial references identify Alstom 029.228 675 as a Drive Control Module | SRE 232.1 | Rev. 07.
What is the exact part number?
The requested identification is 029.228 675. Keep the complete number intact when requesting quotations or replacement verification.
Is every .1 interchangeable with 029.228 675?
No interchangeability should be assumed. A separate public listing identifies SRE 232.1 as 029.223 833, demonstrating that the same family designation can correspond to different part numbers. Compatibility should be established against the original equipment documentation.
What revision is associated with 029.228 675?
The exact public reference identifies Rev. 07. The physical board should still be inspected to confirm the revision of the offered unit.
Can the working voltage and I/O specifications be confirmed from public data?
Not reliably for this exact 029.228 675 configuration. Available sources establish the drive-control classification but do not provide sufficient authoritative electrical documentation for publishing detailed voltage, channel, interface, and environmental specifications.
What should procurement request from a supplier?
Request photographs of the actual nameplate and PCB markings, confirmation of 029.228 675, confirmation of Rev. 07, the physical condition, any repair history, and evidence of functional testing if the unit has been previously used or refurbished.
Is .1 suitable as a generic PLC replacement?
No. It should be treated as a specific drive-control component within its intended Alstom control architecture, not as a general-purpose PLC module. System compatibility must be established from the original cabinet drawings and equipment configuration.
