For IoT or storage-intensive applications

The BL51E is a fanless, maintenance-free box computer for embedded applications in transportation, e.g, in trains, buses or commercial vehicles. Its 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 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 1.6GHz. Other dual/quad core processors of the intel.

Atom E3900 series can be used, giving high scalability in CPU performance.

The box PC features 8GB 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 ten 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 30W with 24VDC nom. (10V to 50.4V), and 110VDC nom. is available as an option.

The power can be switched on and off using an ignition signal on the power connector.
