MAXIMIZE RAIL SYSTEM PERFORMANCE WITH FLEXIBLE, SAFETY-DRIVEN I/O TECHNOLOGY
Modern rail systems require reliable insight across every onboard subsystem — from traction and braking to passenger and power systems.
United Electronic Industries (UEI) provides a rugged, flexible data acquisition and control platform that enables accurate monitoring of key parameters such as vibration, temperature, strain, position, and power. With modular I/O and support for both centralized and distributed architectures, UEI solutions simplify integration, reduce wiring, and support scalable, future-ready rail applications.
Industry Challenges
Rail and transportation systems often operate in harsh and highly dynamic environments. Engineers and operators must address:
Extreme environmental conditions (shock, vibration, temperature swings, EMI)
Complex distributed systems across vehicles and infrastructure
Real-time monitoring and predictive maintenance needs
UEI solutions are designed to meet these challenges with rugged hardware, flexible architectures, and deterministic performance.
UEI Solution Overview
UEI provides a complete ecosystem for data acquisition, embedded control, and monitoring across rolling stock, infrastructure, and development environments.
Key Capabilities
High-speed and high-channel-count data acquisition
Real-time control and closed-loop operation
Edge processing and onboard analytics
Distributed and synchronized measurement systems
Seamless integration with SCADA, PLC, and enterprise systems
Use this as the main DAU cabinet mounted in an equipment bay or cabinet underfloor / inside an electronics compartment, aggregating signals from across the car. Both are modular, rugged, and designed to host multiple I/O boards.
Distributed local DAU near doors, HVAC, or bogie area
Place as a small local node near subsystem clusters where shorter cable runs are helpful. The UEI BRICK4 chassis is compact, rugged, and supports over 90 I/O options.
The UEI DNx-AI-212 fits thermocouples, AI-222 fits RTDs/resistance temperature sensing, and our DNx-MF-102 Multifunction board can pick up mixed analog/digital fan or actuator status.
High-voltage electrical system
(voltage / current / insulation-related measurements)
Our MF-102 supports analog input ranges up to ±80 V with mixed I/O, while DMM-261 provides rugged DMM-style measurements including VDC, VAC, IDC, IAC, and resistance.
Pantograph / roof position equipment
DNx-AI-254 (If LVDT / RVDT position sensors are used)
The DNx-DIO-401 fits door limit/status inputs; DIO-463 adds monitored relay-style output control with voltage/current readback; MF-102 can consolidate mixed status/command signals
Passenger systems
(lighting, indicators, counters)
The DNx-DIO-403 fits high-density digital I/O for lighting and indication logic, DNx-DIO-401 fits isolated digital status inputs, and our MF-102 fits mixed analog/digital tasks.
Our DNx-CAN-503 fits CAN/ARINC-825 links; the DNx-SL-508 fits RS-232/422/485 serial devices; and all UEI chassis provide Ethernet-based aggregation to the supervisory network.
The DNx-MF-102 is useful for direct voltage/current-style analog monitoring and discrete states; our DNX-DMM-261 is useful where more meter-like electrical measurements are needed.
The DNx-AI-211 fits IEPE/ICP vibration sensors, DNx-AI-208 fits strain/load/force-style measurements, and DNx-AI-254 fits LVDT/RVDT displacement/position sensing if that transducer type is used.
Braking system
(pressure, wear, temperature, vibration)
The UEI DNx-AI-212/AI-222 fit temperature channels, the DNx-AI-211 fits vibration sensing, and DNx-MF-102 can collect analog/discrete signals from brake-related sensors or control states
Traction system
(motor current, temperature, inverter status)
The DNx-MF-102 fits mixed analog/discrete channels, DNx-AI-212 and AI-222 boards both fit temperature sensing, and our DNx-CAN-503 fits CAN-connected traction subsystem communications.
