ALSTOM VOOB8-B 12004-106-04 VER：V1.0.0

Description

Product Description

The ALSTOM VOOB8-B 12004-106-04 VER：V1.0.0 is a specific variant of a vehicle output board within Alstom’s rail control and automation systems. This model functions as a dedicated module responsible for controlling and driving high-power outputs, such as lights, relays, contactors, or other actuators onboard a train or tram. The designation VOOB8-B indicates its core function as a Vehicle Output Board with a specific channel configuration, while 12004-106-04 is the detailed assembly part number, and VER: V1.0.0 specifies the critical hardware or firmware version. Integrating the correct ALSTOM VOOB8-B 12004-106-04 VER: V1.0.0 is essential for ensuring reliable command execution for vehicle auxiliary systems. The precise version control, as denoted by V1.0.0, is vital for compatibility within the broader vehicle network.

Product Parameters

• Manufacturer / Brand: Alstom

• Product Type: Vehicle Output Board / Actuator Driver Module

• Model/Function: VOOB8-B (Vehicle Output Board, type B, likely with 8 channels or a specific drive capacity).

• Assembly/Part Number: 12004-106-04

• Version: Hardware/Firmware Version V1.0.0

• Output Type: Typically provides solid-state or relay-based outputs rated for switching inductive and resistive loads common in rail vehicles (e.g., 24V DC, 110V DC at several amps per channel).

• Number of Channels: Likely features 8 independent output channels, as suggested by the “8” in the model code.

• Protection Features: Includes built-in protection against short-circuit, overload, and over-temperature to ensure safe operation and prevent damage to the module or wiring.

• Diagnostic Feedback: Each channel typically provides status feedback (e.g., “On,” “Short-Circuit,” “Open-Load”) to the central vehicle control unit for advanced diagnostics.

• Communication Interface: Connects to the vehicle’s data network (e.g., MVB – Multifunction Vehicle Bus) as a slave device, receiving commands from the central control unit.

• Power Supply: Operates from the vehicle’s low-voltage DC supply, compliant with railway standards like EN 50155.

Advantages and Features

• High Reliability for Critical Functions: The ALSTOM VOOB8-B 12004-106-04 VER: V1.0.0 is designed for the demanding railway environment, offering fail-safe or fault-tolerant operation for passenger safety and system availability.

• Integrated Diagnostics: Provides detailed per-channel status information, enabling predictive maintenance and rapid fault isolation, which reduces vehicle downtime.

• Robust Load Driving: Capable of directly switching high-current inductive loads typical in rail applications (e.g., contactor coils, lamps, heaters) without requiring intermediate relays.

• Network Integration: Seamlessly integrates into the standardized vehicle communication network, allowing for centralized control and monitoring.

• Compact and Modular Design: Saves space in crowded electrical cabinets and allows for easy replacement as a unit.

• Version-Specific Compatibility: The specified VER: V1.0.0 ensures the module behaves exactly as expected by the vehicle’s main software, preventing integration issues.

Application Cases in Key Fields

• Passenger Rail Vehicle Auxiliary Control: Primary application is controlling interior and exterior lighting, door indicator lights, passenger information display power, and HVAC system actuators (e.g., fan relays, damper motors).

• Train Door Systems: Used to provide the power output to control door opening/closing mechanisms, door locks, and safety light curtains.

• Brake and Pneumatic System Control: Can actuate solenoid valves for the pneumatic brake system or control indicators for brake status.

• Cab and Console Functions: Drives indicators, alarms, and control relays in the driver’s cab based on commands from the train control system.

Comparison with Competing Products

Competing products are similar output modules from other rolling stock manufacturers like Siemens Mobility, Bombardier Transportation, or Strukton. The ALSTOM VOOB8-B 12004-106-04 VER: V1.0.0 is distinguished by its specific electrical characteristics, form factor, communication protocol implementation, and, most importantly, its validation within Alstom’s vehicle control architecture. Generic industrial output modules from vendors like Wago or Phoenix Contact offer similar switching capabilities but lack the specific MVB communication, environmental qualifications (EN 50155), and the pre-defined vehicle-specific configuration and diagnostics that make the VOOB8-B a plug-and-play solution within its native ecosystem.

Selection Suggestions and Precautions

• Version Verification is Critical: The VER: V1.0.0 is not optional. Using a board with a different firmware version (e.g., V1.1.0) could lead to communication errors or incorrect behavior, even if the hardware part number is the same. Always match the full specification.

• Confirm Load Requirements: Verify that the output current and voltage rating per channel of the VOOB8-B is sufficient for the specific load you intend to connect (including inrush currents for lamps or solenoids).

• Check Network Address and Configuration: The module will have a pre-configured or configurable address on the vehicle network (MVB). This must be correctly set for the central controller to communicate with it.

• Handle as ESD-Sensitive: Treat the module as a sensitive electronic device. Use proper anti-static precautions during handling and installation.

• Source from Authorized Railway Channels: Due to its safety-related application, procure the ALSTOM VOOB8-B 12004-106-04 VER: V1.0.0 only through Alstom’s official railway parts distribution network or certified aftermarket suppliers to guarantee authenticity and traceability.

• Professional Installation and Testing: Installation should be performed by qualified personnel. After installation, functional testing of each output channel through the vehicle’s diagnostic system is mandatory.
