Leroy Automation’s BRIO I/O modules are essential components for designing control-command systems in the railway sector. Designed to be used with central computers, these modules, qualified according to the EN 50155 standard, ensure robust performance and optimal reliability in demanding environments. The BRIO (Basic Remote Input Output) platform complies with the SIL0 standards of the EN 50126, EN 50128, and EN 50129 standards, offering a base solution for managing railway signals.
The BRIO range also includes specific modules to meet advanced technical needs:
BRIO SIL2: I/O module with SIL2 functional safety level, ideal for applications requiring additional safety guarantees.
BRIO SSPC: Semiconductor power controller, designed for efficient energy management in railway systems.
BRIO CEE: Energy exchange controller, for optimized energy transfer and management in trains.
With over 15,000 installations worldwide, the BRIO range is an essential reference for railway professionals, providing high-quality solutions for all your train control and command projects.
The serial ports list depends of the models.
The generic BRIO range includes several modules based on the type and number of inputs/outputs.

The Fail Safe Module (FSM) is SIL2 CERTIFER certified in accordance with EN50126, EN50128 and EN50129.
It has :
A BRIO CEE is installed in each car. It monitors the car’s electrical sources from auxiliary power converters.
If the car loses its power source, it dialogues with the BRIO CEE to allow the car to be recharged via the two adjacent cars. The rescue is complete if the car is surrounded by two healthy cars that do not rescue other cars.
The BRIO Solid State Power Controller (SSPC) features 8 monitored SST outputs that can be remotely reset via the network.
6 outputs can switch up to 6A and 2 outputs up to 10A.
According to a 1000-point disjunction curve, previously configured and saved, it cuts the output in less than 1 μs if the intensity exceeds a defined threshold.
On each output, it calculates the power and measures the temperature. The calculations are made by an FPGA coprocessor.
Remote reset: After disjunction, the output can be closed by a TCMS command via the Ethernet port.
