Schneider Electric introduces a PLC I/O system that is future-ready and railway-certified
30 July 2025
The new Modicon Edge I/O NTS is a modular input/output (I/O) solution that delivers robustness, flexibility, scalability and cybersecurity for the challenging railway environment.
Schneider Electric has launched the Modicon Edge I/O NTS as a future-ready distributed I/O system that lays a foundation for digitalisation in the railway industry.
The new solution will support growing data transmission needs with in-built cybersecurity and high availability. It has been certified for railway applications due to its mechanical robustness and extended operating temperature range of -40°C to +70°C.
Dave Sutton, Product Marketing Manager for Industrial Automation at Schneider Electric, said, “Railways face stringent regulatory frameworks, growing cybersecurity threats, and need high uptime across a wide variety of devices and architectures.
“The Modicon Edge I/O NTS meets those needs by providing high availability, cybersecurity, and performance for rail operators in a package that is flexible, efficient and compact for system integrators and OEMs.
“Embracing next-generation I/O systems will accelerate digital transformation journeys in even the most challenging environments.”
As a new-generation I/O platform, Modicon Edge I/O NTS is designed to connect to a wide variety of smart devices, meters, sensors and edge devices distributed widely across onboard and trackside applications.
It enables railway operators, system integrators and OEMs serving the industry to integrate the data they need to continuously optimise efficiency, agility, and sustainability:
• Futureproof railway cybersecurity
The Modicon Edge I/O NTS is the first I/O system with in-built cybersecurity protection meeting the EN 62443 standard
• Increase flexibility
Scalable and customisable I/O islands support a broad range of data protocols in a compact modular design that provides more functionality in less space
• Reduce unplanned downtime
The only I/O system available with unrestricted hot swap capabilities, which will keep data transmission online while replacing individual modules.
• Withstand the rail environment
With a Declaration of Conformity (DoC) covering the railway standards EN 50155, EN 50121-3-2, EN 50121-4 and EN 50121-5, and EN 45545 (Smoke Fire).
• Save time with adaptive engineering tools
Simplified wiring and a network interface enables remote configuration for rapid commissioning and supporting quick repair time for critical signalling, control, and monitoring systems.
• Optimise performance and availability
Open Ethernet protocols deliver connectivity with embedded data intelligence to a variety of devices and architectures.
As the UK rail sector undergoes a digital transformation, operators, system integrators and OEMs can adopt Schneider Electric’s Modicon Edge I/O NTS to support high availability for data, protecting passenger and freight services.
