duagon BL72E box PC

duagon’s BL72E is a fanless, maintenance-free box computer for embedded applications in transportation. It is based on AMD’s Ryzen V1000 APU family, featuring good power-per-watt performance and a Radeon Vega next-generation 3D graphics engine. With up to four high-performance processor cores, AMD virtualisation support and up to 32 GB soldered-down DDR4 SDRAM, it offers powerful computing performance for handling data-intensive workloads.

A robust PC with high communication and storage capacity, the product is suitable for the rail and public transport industry, especially for onboard applications such as internet on board, positioning via GNSS, CCTV/recording, passenger entertainment and more. Two basic processor configurations matching the option extensions specifically support the user in running or evaluating their system.

Numerous wireless options are available to provide vehicle localisation or internet for passengers. These include a GNSS positioning interface, two PCI Express mini-card slots and two M.2 slots for implementing mobile service standards up to 4G LTE or WLAN IEEE 802.11 and their derivatives. In total, the PC contains eight externally accessible micro SIM card slots. In addition, it can be supplemented with a second I/O card that provides further LTE modems, memory and I/O.

The SATA HDD/SSD shuttle has the necessary storage capacity for video surveillance systems. An eMMC memory and an M.2 slot for PCIe storage (NVMe) provide further capacities. With its strong processing power, scalable memory and wireless connectivity, the PC is also suitable for entertainment server applications.

The device supports a DisplayPort interface with a maximum resolution of 4K. A variety of other I/Os are available, including four Gigabit Ethernet, audio, two USB 3.2, RS232, RS422/RS485 and IBIS slave. An optional MVB or CAN bus interface can be implemented, as well as digital inputs and outputs.

The PC has a wide-range power supply (24-110 VDC nominal) and complies with the railroad standard DIN EN 50155. An ignition input signal is used to remotely turn the system on and off, thus saving power. When the system is not needed, it can be shut down remotely in a safe and controlled manner. With its robust aluminium housing with cooling fins that serve as heat sinks, the PC is capable of conduction cooling. This enables fanless operation at temperatures from -40 to +70°C (+85°C for up to 10 min).
