Forecr RAIBOX-ORNX-AA NVIDIA Jetson Orin NX 8GB IP67 EN 50155 Computer for Rolling Stock

Not every onboard job needs the biggest module: a secure gateway, a monitoring node or a single camera model mainly needs sealed hardware, isolated I/O and a supply range that suits the fleet. The RAIBOX-ORNX-AA covers that with the NVIDIA Jetson Orin NX 8GB in an EN 50155 computer from the Forecr RAIBOX-ORNX series, rated IP67 for rolling-stock installation.

The 8GB Orin NX gives the RAIBOX-ORNX-AA GPU-accelerated inference for in-cab and exterior cameras, data processing for train control and monitoring systems, and gateway duty between onboard networks. It runs Ubuntu 20.04 with JetPack 5.1 and draws under 40 W. Where larger models or more streams are planned, the 16GB RAIBOX-ORNX-AB uses the same design with twice the memory.

Camera feeds arrive on four GMSL inputs with FAKRA connectors, and two Gigabit Ethernet ports handle network traffic. Field wiring runs through two isolated CAN bus ports, two isolated RS-232/422/485 ports and four isolated digital inputs and outputs, while one USB 3.1 Type-A port, one USB 3.1 Type-C port and an HDMI 2.0 output serve local access. Every field connector is a Phoenix Contact M12: X-coded for both Ethernet ports and A-coded for power, serial, CAN and digital I/O. Storage goes on two M.2 Key-M slots, an M.2 Key-B socket with a SIM slot adds LTE or 5G, an M.2 Key-E socket takes WiFi and Bluetooth, and the supply is 10-75V DC.

Forecr designs the RAIBOX-ORNX-AA to meet EN 50155 and EN 45545-2, with IP67 ingress protection and resistance to shock, vibration and electromagnetic interference. Rated from -25°C to +85°C in a 275 x 200 x 75 mm enclosure, this EN 50155 computer suits train monitoring, railway infrastructure gateways and transport, agriculture or marine vehicles.
