I. Core Functions and Key Features

1. Multi-System Control
   • Manages essential train functions such as motor speed regulation, braking systems, door operations, HVAC control, and electrical system oversight.
   • Integrates with railway signaling systems to coordinate track circuit status, signal light activation, and switch/turnout control.
2. Power Supply Management
   • Converts 220V AC or 380V AC input voltage to stable DC outputs (e.g., ±5V, ±12V, ±15V, ±18V, 24V DC) for onboard electronics.
   • Features short-circuit, overload, and overvoltage protection to ensure reliability in harsh environments.
3. Communication Capabilities
   • Supports RS-422, Ethernet (UDP/IP), and Modbus RTU protocols for seamless integration with central control systems, SCADA, and other railway infrastructure components (e.g., LEU/BDU units).
   • Enables real-time data transmission for diagnostics, status monitoring, and remote configuration.
4. Robust Design and Certification
   • Constructed with industrial-grade materials to withstand -40°C to +70°C temperatures, high humidity, and vibration.
   • Complies with international standards such as CE, ISO 9001, and railway-specific safety requirements (e.g., IEC 62443 for cybersecurity).
5. Compact and Modular Architecture
   • Dimensions: 50 cm (W) × 30 cm (H) × 20 cm (D) (approx.), facilitating DIN rail or panel mounting in control cabinets.
   • Modular design allows easy expansion and maintenance, reducing downtime.

III. Application Scenarios

1. Railway Signaling Systems
   • Monitors track circuits, signal lights, and turnout status to ensure safe train routing.
   • Transmits real-time data to central control systems for traffic management and fault detection.
2. Train Onboard Control
   • Regulates motor speed, braking, and door operations to enhance passenger safety and operational efficiency.
   • Integrates with HVAC and lighting systems for optimal cabin environment control.
3. Power Supply for Railway Infrastructure
   • Provides stable power to field devices (e.g., sensors, actuators, and communication modules) in railway substations and depots.
4. Predictive Maintenance
   • Logs operational data and diagnostics for predictive maintenance, reducing unplanned downtime.

IV. Integration and Compatibility

• TRENO Platform: Seamlessly integrates with ALSTOM’s TRENO railway signaling and automation systems.
• Third-Party Systems: Supports interoperability with SCADA, LEU/BDU units, and other railway control systems via standard protocols.
• Expansion Modules: Can be paired with ALSTOM’s I/O and communication modules for scalable solutions.

V. Procurement and Usage Notes

1. Authorized Channels: Purchase through ALSTOM-authorized distributors to ensure authenticity and warranty coverage.
2. Installation: Requires qualified technicians to follow ALSTOM’s guidelines for proper grounding and wiring.
3. Maintenance: Regularly check voltage outputs, ventilation slots, and firmware updates to ensure optimal performance.
4. Documentation: Request datasheets and installation manuals from ALSTOM or certified suppliers for detailed configuration instructions.
