The BL70W is a fanless, maintenance-free box computer that has been designed for independent use or as display computer electronics for embedded wireless applications in transportation, e.g. in trains, commercial vehicles, mobile machines or airplanes.

The BL70W is powered by an Intel Core i7-3517UE CPU, running at 1.7 GHz. Other processors of the 3rd generation Intel Core i7 family can be used which makes for high scalability in CPU (single/dual/quad core) performance.

The BL70W is equipped with 4 GB of DDR3 SDRAM and offers microSD card and mSATA slots.

Wireless Communication

Four PCI Express Mini Card slots each with dual micro-SIM make it possible to flexibly implement the whole range of wireless interfaces such as mobile service standards up to 4G LTE or WLAN/WLAN IEEE 802.11, and derivates. A GNSS interface supporting positioning systems GPS and GLONASS complements the possibilities.

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 special rugged aluminum housing with cooling fins serves as a heat sink for the internal electronics and in this way provides conduction cooling.

Railway-Compliant PSU with Ignition Function

The BL70W comes with its own integrated 30W 24 VDC nom. class S2 wide-range power supply and is in compliance with EN 50155 and ISO 7637-2 (E-mark for automotive). 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.

Flexible System Design

The various CPU options with the available selection of external interfaces (realized via separate graphics and I/O interface boards within the system) makes for an extremely flexible system design that can quickly be tailored to a vast number of applications.

The BL70W supports up to two DisplayPort interfaces with full HD resolution. In addition, a multitude of other I/O is available at the front panel, including two Gigabit Ethernet, two USB 2.0, variable slots for legacy serial I/O (e.g. RS232) or CAN bus, general purpose inputs and relay outputs.
