Fanless railway box PC with AMD Ryzen V1000 APU

Manufacturer: duagon MEN
duagon BL72E

The duagon BL72E is a fanless, maintenance-free AMD Ryzen based box computer for embedded applications in transportation, e.g., in trains. It offers a SATA HDD/SSD shuttle providing the storage capacity necessary for entertainment servers or video surveillance systems, plus eMMC memory and an M.2 slot for PCIe based storage (NVMe).

Cost-Efficient High-End Processor Performance

The BL72E is based on AMD's Ryzen V1000 APU family featuring excellent power-per-watt performance and a Radeon Vega next-generation 3D graphics engine. With up to four high-performance processor cores and AMD virtualization support, and up to 32 GB soldered-down DDR4 SDRAM, the BL72E offers powerful computing for handling data-intensive workloads efficiently, e.g. for implementation of complex algorithms for deep learning or machine intelligence.

Multi-Talent for Wireless Communication

The BL72E can take over typical onboard wireless functions, such as an Internet connection for passengers or locating the vehicle. A GNSS positioning interface is available. Two PCI Express Mini Card slots and two M.2 slots provide maximum flexibility in implementing mobile service standards up to 4G LTE or WLAN IEEE 802.11 and derivates.

A total of eight externally accessible micro-SIM card slots is available. As an option, the box can be delivered with a second I/O board offering additional LTE modems, storage and I/O.

A multitude of I/O

The BL72E supports one DisplayPort interface with a maximum of 4K resolution. A multitude of other I/O is available, including four Gigabit Ethernet, audio, two USB 3.0, RS232, RS422/RS485, IBIS, digital inputs and outputs. An MVB master or slave or a CAN interface can optionally be implemented.

Railway-Compliant PSU with Ignition Function

The BL72E comes with a class S2 wide range power supply and complies with EN 50155. The power can be switched on and off using an ignition signal on the power connector.

Fanless Operation for Mobile Applications

The system offers long-term availability for 10 years and is designed for fanless operation at temperatures from -40 °C to +70 °C (+85 °C for up to 10 minutes). Its rugged aluminium housing with cooling fins serves as a heat sink and provides conduction cooling.
