Rugged Embedded Computer with Intel Apollo Lake I

A Multi-Talent for Wireless Communication

The BL51E can take over typical on-board 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 aluminum 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.
