Intel® Atom E3900 Series, -40 to +70/85°C Operating
The BL51E is a fanless, maintenance-free box computer for embedded applications in transportation, e.g., in trains, buses or commercial vehicles. The HDD/SSD shuttle provides the storage capacity necessary for entertainment servers or video surveillance systems. A vast number of I/O functions and options seamlessly link the BL51E to the IoT, making vehicles smart.
A Multi-Talent for Wireless Communication
The BL51E can take over typical onboard wireless functions, whether it is an Internet connection for passengers or locating the vehicle. Four PCI Express Mini Card slots each with two micro-SIM slots and dual SIM support provide maximum flexibility in implementing mobile service standards up to 4G LTE or WLAN/WLAN IEEE 802.11, and derivates. A GNSS positioning interface supporting GPS and GLONASS rounds out the options.
Solid Processing Performance
The BL51E is powered by an Intel Atom E3950 running at 1.6 GHz. Other dual/quad core processors of the Intel Atom E3900 series can be used, giving high scalability in CPU performance. The box PC features 8 GB DDR3 SDRAM and offers an SD card and a SATA HDD/SSD shuttle both accessible at the rear, plus in-system eMMC memory.
Fanless Operation for Mobile Applications
The system 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 for the internal electronics and provides conduction cooling.
A Multitude of I/O
The BL51E supports two DisplayPort interfaces with maximum 4K resolution. A multitude of other I/O is available at the front, including four Gigabit Ethernet, two of them with PoE support, two USB 2.0, one slot for legacy serial I/O (RS232) and one CAN bus, general purpose inputs and relay outputs.
Railway-Compliant PSU with Ignition Function
The BL51E comes with its own integrated class S2 wide range power supply and is in compliance with EN 50155 and ISO 7637-2 (E-mark for automotive). Standard versions support 30 W with 24 VDC nom. (10 V to 50.4 V), and 110 VDC nom. is available as an option. The power can be switched on and off using an ignition signal on the power connector, and a run-down time after switching off the power can be adjusted by software.
