Product Description
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. A GNSS positioning interface
supporting GPS and GLONASS is available. 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.
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, four
Gigabit Ethernet, two with PoE+ capability, two USB 2.0, legacy serial I/O (RS232) and CAN
bus, general purpose inputs and relay outputs.
Railway-Compliant PSU with Ignition Function
The BL51E has a class S2 wide range power supply in compliance with EN 50155 and
prepared for 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 ignition signal can be adjusted by software.
Long-Term Available and Future-Safe
Long-term availability until 2027 ensures an extended product life and future-safety.
