What Is Covered by EN 50121-4?
EN 50121-4 certification applies to railway installations located trackside and in stations. It ensures that computers and networking devices meet strict EMC requirements so they neither interfere with signalling systems nor suffer disruption from them.

Where Are EN 50121-4 Systems Deployed?
Typical uses include trackside monitoring, CCTV, signalling cabinets and communication systems. Rugged housings, wide operating temperatures and surge protection allow them to function reliably in exposed, electrically noisy rail environments.

Why Source From a UK Supplier?
We deliver EN 50121-4 certified computers with configuration and testing options from the UK. This provides rail operators and contractors with confidence that hardware is compliant, deployment-ready and supported throughout its service life.
