TES-250-M12Managed 5-port M12 switch with EN 50155 certification for rolling stock
- Manufacturer
TES-250-M12 is a managed Ethernet switch with 5 Fast Ethernet ports on M12 connectors, intended for railway and rolling stock applications where the cabling has to withstand vibration and humidity. EN 50155 certification defines its use on board vehicles.
Redundancy relies on the O-Ring, O-Chain and RSTP protocols, with ring recovery in 10 ms. The power section accepts a wide 12~48 V input with protections against overload, overcurrent (OCP) and reverse polarity.
