Embedded Controller Modules Input/Output TCMS – Railway Systems

Vehicule Control Units - VCU

Leroy Automation offers VCU central controllers for TCMS, compliant with EN 50155/IEC 60571 standards, specifically designed for railway systems. Based on the RIOM platform, they provide reliable solutions for the control and management of a Train Control and Management System (TCMS).

Key features:

Control and management of railway systems
Communication gateway between fieldbus and Ethernet network
Automation of subsystems (HVAC, doors, braking, fire safety)

With over 50,000 installations worldwide, our controllers easily integrate into SIL2 architectures and offer a wide range of models and configurations, tailored to the specific needs of railway projects.
