Forecr RAIBOX-ORNX NVIDIA Jetson Orin NX EN 50155 Computers with IP67 Sealing

Onboard rail electronics have to ride out shock, vibration, electromagnetic interference and temperature swings for years, often on supply voltages that differ from one fleet to the next. Camera-based monitoring adds a further demand, since video has to be processed on the train rather than sent back over a cellular link. The Forecr RAIBOX-ORNX series answers that with EN 50155 computers that put the NVIDIA Jetson Orin NX module into an IP67-rated enclosure, drawing under 40 W, for train control and monitoring systems and secure gateways on railway infrastructure.

Both models share one design. Four GMSL camera inputs on FAKRA connectors bring in onboard cameras, while two Gigabit Ethernet ports, one USB 3.1 Type-A port, one USB 3.1 Type-C port and an HDMI 2.0 output at up to 3840 x 2160 handle networking and local devices. Two isolated CAN bus ports, two isolated RS-232/422/485 ports and four isolated digital inputs and outputs connect train systems. 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. Two M.2 Key-M slots take SSDs, an M.2 Key-B socket with a SIM slot carries LTE or 5G, and an M.2 Key-E socket adds WiFi and Bluetooth. Every RAIBOX-ORNX takes a 10-75V DC input and runs Ubuntu 20.04 with JetPack 5.1. An accelerometer and temperature sensor sit on the board, and the isolated side of the design covers power, Ethernet, serial, CAN and digital I/O.

The two models differ only in module memory. The RAIBOX-ORNX-AA carries the Jetson Orin NX 8GB, sized for gateway duty, monitoring and single-model vision on the vehicle. The RAIBOX-ORNX-AB fits the Jetson Orin NX 16GB, the module behind Forecr’s 100 TOPS figure for the series, with twice the memory for larger models and more concurrent camera streams. Neither model changes the enclosure, connectors or power input, so a fleet can mix both on one wiring design.

The RAIBOX-ORNX is designed to meet EN 50155 and EN 45545-2, with IP67 ingress protection, resistance to shock, vibration and electromagnetic interference, and a -25°C to +85°C operating range in a 275 x 200 x 75 mm enclosure weighing 2750 g. That suits these EN 50155 computers to train control and monitoring, secure gateways for railway infrastructure, and transport, agriculture and marine installs where dust, water and vibration are part of daily service.
