  • COMPANY PROFILE

    Manufacturer of Automation Products for Harsh Environments

    Since 1997, Leroy Automation has been designing and manufacturing automation products for implementing train control and management systems. We are able to offer commercial-off-the-shelf products and custom design, covering a full range of control and monitoring management tasks in train operation from doors to heating, ventilation, braking and lighting.
    Leroy Automation is certified to ISO 9001:2008 and IRIS.

    Embedded PLC for train control and management systems (TCMS)

    Since 1997, Leroy Automation has produced 30000 RIOM. The full Ethernet compliant fourth generation is currently in production.

    RIOM is an EN50155-certified embedded PLC designed to be integrated into train control and management systems. It can control local automatisms, command gateways or supervision functions. The CPU board has one MVB or Ethernet channel, one CAN 2.0 channel and two asynchronous serial links. The programming for our PLC products is in IEC61331-3 languages with the Straton workbench or C language with a Linux SDK. The RIOM accepts 32 digital inputs+16 digital outputs or 64 inputs + 32 outputs.

    Ethernet remote terminal for embedded rail applications

    BRIO is an EN50155-certified remote terminal linked on Ethernet networks for embedded railway applications. The specifications include:

    • 36mm wide x 262mm high x 183mm deep board in an IP30 metallic cassette.
    • One 10/100 base T Ethernet TCP-UDP/IP channel. The protocol on Ethernet is CIP EtherNet/IP or Modbus/TCP.
    • Full range power supply 24Vdc to 110Vdc
    • 40 digital inputs: full range input voltage (24Vdc to 110Vdc)
    • 8 relays outputs
    • 2 solid state relays
    • 1 analogue output voltage 0-10Vdc or 0-20mAdc

    PLC for rail substation automation

    The LT energy range is suitable for high-voltage switch management in electrical substations. Inputs / output blocks are specially designed to control circuit breakers, switches and isolating switches. The Software tool is the STRATON workbench of the Copalp company. The specifications include:

    • Data storage (1Mb max)
    • Embedded web pages
    • FTP server
    • Ethernet DNP3.0 level two slave protocol
    • Serial DNP3.0 level two slave protocol
    • Modbus master and slave protocols

    The secure input / output block can control four high-voltage switches. The command of the open relay outputs is four times redundant.

    PLC product references

    RIOM products were embedded in high-speed trains, trains, trams and metros.

    The high-speed trains include the Alstom AGV world rail speed record train (574.8 km/h) and NTV (Italia).
    The trains include West Coast Main Line and Juniper trains in the UK, Fortaleza in Brazil, Cercanias in Spain, DB Frame in Germany, Stockholm in Sweden and Copenhagen in Denmark, and Tage in Portugal. The winterized version operates in Russian trains.

    The trams include Jerusalem, Lyon in France and Nantes in France.

    The metros include Budapest in Hungary, Barcelona in Spain, Helsinki with Siemens Mobility in Finland.
    The BRIO operates in the TCMS of Alstom’s trains for PRASA (South Africa).

    LT energy has been used by the 25kV French high-speed train lines (FIP + HNZ protocols) and the South Korean high-speed train network (Modbus + DNP3 protocols).
