The EN50155 certified AI Railway Computer RML A4NX has four PoE Gbit interfaces (Power over Ethernet). This allows for sensors such as cameras, lidars, radars and others to be connected without requiring their own power supply. The Railway Computer also features digital I/Os, CAN and RS-232. The AI-Railway Computer RML A4NX is suitable for rolling-stock applications and has an integrated galvanically isolated power supply with a DC input voltage range of 16.8V – 137.5V. This allows the railway computer to be directly connected to 24V, 36V and 110V systems. The RML A4NX is suitable for CCTV and computer vision applications as well as for train control and communications applications. With optional radio connectivity (5G/4G, Wi-Fi) the computer is suitable as a gateway or for access to your cloud.
