The available records consistently identify 3BHE029063R0101 as PA D238 A101: PEC INT CM. Historical import records describe it as a PEC INT CM adapter, while more recent railway procurement documentation identifies it as a subassembly for an inverter/traction converter. Those descriptions are sufficient to establish its equipment role, but they do not provide a reliable basis for publishing voltage, current, connector pinout, dimensions, or environmental ratings.
Product Introduction
The ABB PAD238A101 3BHE029063R0101 is a PEC INT CM component used in ABB traction-converter equipment. Railway procurement records specifically associate the part with ABB IGBT-based three-phase locomotive traction converters, and an EU160-related specification identifies the component as PA D238 A101: PEC INT CM.
For maintenance engineers, the important point is that this is an application-specific converter component, not a generic PLC communication card or general-purpose I/O module. Historical ABB trade records also identify 3BHE029063R0101 as a PEC INT CM adapter, reinforcing that its electrical and mechanical interfaces must be evaluated within the intended PEC/traction-converter assembly.

Engineering Pain Point
The main replacement risk is identifying the part only by the short designation PAD238A101 and assuming that any PEC-related interface board will substitute. Railway procurement records explicitly specify the complete ABB number 3BHE029063R0101, and one EU160 application record further identifies RDO:3.1 / RT: EU160. This indicates that the installed converter configuration matters.
Typical Applications
- ABB IGBT-based three-phase locomotive traction converters.
- EU160 railway traction-converter equipment where the specified RDO/RT configuration matches.
- Replacement of failed or damaged PEC INT CM assemblies during traction inverter maintenance.
- Converter repair programs where the original ABB article number must be maintained for configuration control.
Technical Pitfalls to Avoid
- Do not treat PAD238A101 as a generic I/O card. Its documented application is specifically tied to ABB traction-converter equipment.
- Match the complete ABB article number. The correct identification is 3BHE029063R0101, not simply “D238” or “PAD238.”
- Check the converter vehicle/application before replacement. An EU160 procurement specification identifies the component as RDO:3.1, RT: , showing that application configuration can be part of the identification.
- Do not assume connector compatibility from physical appearance. Public records do not provide a verified pinout for this exact assembly. Connector position, mating hardware, and PEC architecture should be checked against the converter drawings.
- Verify the installed hardware revision. For railway traction equipment, firmware, control parameters, converter configuration, and commissioning records can matter as much as the board article number.
- Do not substitute a similarly named PEC component without engineering approval. Historical records contain other PEC interface and control components with different ABB article numbers, so functional similarity does not establish interchangeability.

Procurement Note
For , procurement should be based on the complete ABB article number plus the installed converter application, not the short model alone. If the equipment is an installation, record the applicable RDO/RT configuration shown in the maintenance documentation. Before commissioning a replacement, verify the board marking, hardware revision, converter type, mating connectors, control configuration, and applicable ABB engineering drawings.
The available public evidence confirms the traction-converter / PEC INT CM role, but does not adequately verify exact electrical ratings, connector pinout, dimensions, or environmental limits. Those values should be taken from the installed converter documentation or ABB controlled documentation rather than inferred from similarly named PEC products.
