Description
Product Overview
ALSTOM BGTR8HE 24491276A1004 is a VME-based industrial control rack designed for ALSTOM/Converteam automation architectures used in large drive and power conversion applications. The rack provides the structural platform, backplane connectivity, and power distribution required for multiple control modules operating as a coordinated system.
The ALSTOM BGTR8HE 24491276A1004 is commonly installed as the central hardware enclosure for control electronics in systems such as MV drives, converter systems, and industrial electrical control equipment. Unlike a standalone controller module, the rack itself does not execute application logic; instead, it provides the infrastructure that allows CPU cards, communication boards, and interface modules to exchange data and receive stable power.
Typical architecture:
Power Supply → BGTR8HE Rack → CPU / Communication Modules → PIB Interface Boards → Converter Control System
The BGTR8HE 24491276A1004 supports modular maintenance by allowing individual plug-in boards to be installed or replaced without replacing the complete control assembly. Associated boards such as PIB903, PIB102A 3BEB0180, and PIB310 3BHB0190 are used within related ALSTOM control architectures for power and signal interface functions.
Typical applications include:
- Medium-voltage motor drive systems
- Marine propulsion control systems
- Industrial converter equipment
- Power generation auxiliary systems
- Legacy ALSTOM automation platforms
For replacement projects, engineers should verify the complete rack identification, installed module arrangement, backplane type, power supply configuration, and existing software architecture. A rack assembly with the same mechanical dimensions may not be interchangeable if the backplane wiring or module compatibility differs.
Because many ALSTOM/Converteam systems remain in operation after long service periods, maintaining a spare BGTR8HE 24491276A1004 assembly can simplify restoration after rack-level faults such as damaged backplanes, connector failures, or power distribution issues.

Main Features and Advantages
Modular VME Control Architecture
The main advantage of the ALSTOM 24491276A1004 is its modular rack design.
The rack allows integration of:
- Processor boards
- Communication modules
- Digital and analog interfaces
- Power interface boards
- Diagnostic modules
This structure simplifies maintenance because individual boards can be serviced without replacing the complete control cabinet.
Backplane-Based Signal and Power Distribution
The rack backplane provides:
- Module interconnection
- Control signal routing
- Logic power distribution
- Communication paths
A damaged backplane or poor connector contact can create multiple system symptoms, including communication loss, module detection errors, and unstable controller operation.
Designed for ALSTOM Industrial Drive Platforms
The 24491276A1004 is associated with ALSTOM/Converteam systems where reliable coordination between control electronics and power equipment is required.
Typical system components include:
- PIB interface boards
- VME processor cards
- Drive communication modules
- Converter control assemblies
Supports Legacy System Maintenance
Many industrial installations continue operating with ALSTOM control platforms because replacing the complete automation architecture can require extensive engineering work.
Maintaining spare rack assemblies helps support:
- Faster hardware restoration
- Reduced production interruption
- Preservation of existing application software
Cabinet-Level Integration
The rack provides a standardized installation platform for industrial control hardware.
Important maintenance checks include:
- Rack grounding
- Power supply condition
- Backplane contact quality
- Cooling airflow
- Module seating

Engineer’s Guide: Field Pitfalls
⚠️ Verify Complete Rack Configuration
Before replacement, document:
- Installed cards
- Slot positions
- Backplane type
- Power modules
- Communication wiring
The empty rack alone does not define system compatibility.
⚠️ Check Backplane Condition
Common rack-related failures:
- Oxidized connectors
- Loose card contacts
- Damaged traces
- Grounding problems
⚠️ Confirm Power Compatibility
Verify:
- Incoming AC voltage
- Rack power supply type
- DC output rails
- Load requirements
⚠️ Preserve Module Mapping
Before removing the rack:
- Photograph card positions
- Label cables
- Record jumper settings
- Backup configuration files
⚠️ Refurbished Rack Testing Requirements
A proper evaluation should include:
- Visual inspection
- Backplane continuity test
- Power rail verification
- Slot communication test
- Module recognition test
- System boot verification
- Extended operation test
A rack that accepts modules does not confirm complete system functionality.
