ALSTOM VPS 12004-102-03 V1.0.0 Embedded I/O module
The ALSTOM VPS 12004-102-03 is a high-density embedded I/O module from ALSTOM’s Advant OCS (Open Control System) family, designed for mission-critical process automation in power generation and rail transportation systems. This 32-channel isolated input module features <0.1% measurement accuracy across its 4-20mA/0-10V analog inputs, making it essential for turbine vibration monitoring and traction motor control applications. The VPS 12004-102-03 implements ALSTOM’s patented Cross-Channel Interference Rejection technology, reducing signal crosstalk to <0.05% in high-electromagnetic environments.
As part of the Advant Controller 800 series, this module supports hot-swapping with <5ms signal interruption during maintenance operations. Its conformal-coated PCB withstands 95% relative humidity in coastal substations while maintaining IP67 protection when installed in ALSTOM-certified enclosures. The ALSTOM VPS 12004-102-03 integrates seamlessly with MODBUS TCP/IP networks through its embedded dual-port switch architecture.

Key Features and Advantages:
Signal integrity assurance: The ALSTOM VPS 12004-102-03 employs 16-bit delta-sigma ADCs with 64x oversampling, eliminating aliasing errors in variable frequency drive (VFD) monitoring applications. Its active thermal compensation maintains ±0.2% accuracy across full temperature ranges.
Industrial resilience: Dual redundant power inputs with automatic load balancing ensure continuous operation during voltage dips. The module’s shock-resistant design withstands 10g impacts (IEC 60068-2-27) in locomotive applications.
Diagnostic intelligence: Embedded health monitoring tracks channel drift patterns and predicts sensor failures 200-400 hours in advance. The front-panel LED matrix provides real-time status visualization across all 32 channels simultaneously.
Application Areas:
The ALSTOM VPS 12004-102-03 excels in:
- Thermal power plants: Boiler drum level monitoring
- High-speed rail: Pantograph contact force measurement
- Wind farms: Gearbox oil pressure monitoring
- Chemical processing: Batch reactor temperature control
In metro signaling systems, this module processes axle counter inputs while filtering out traction power harmonics up to 2.5kHz. Its railway-certified variant (VPS 12004-102-03R) meets EN 50155 standards for onboard rolling stock equipment.
