Intel Atom E3900 Series, -40 to +85C Operating

Manufacturer: duagon MEN

MEN's BC51M is a maintenance-free box computer that has been designed for use in vehicles, e.g. in trains, commercial vehicles, mobile machines or aeroplanes for applications such as Internet-On-Board, positioning via GNSS, entertainment or predictive maintenance. An MVB option is available to support integration into the Train Communication Network (TCN).

Wireless Communication

The BC51M can take over typical onboard wireless functions, whether it is an Internet connection for passengers or locating the vehicle. Two PCI Express Mini Card slots and two micro-SIM slots provide flexibility in implementing mobile service standards up to 4G LTE or WLAN/WLAN IEEE 802.11 and derivates.

Solid Processing Performance

The BC51M is powered by an Intel Atom processor from the E3900 series running at up to 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 slot. A SATA hard-disk/solid-state drive can be installed within the housing as an option.

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 aluminium 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 BC51M comes with an integrated 30W wide-range DC/DC converter and is compliant with EN 50155 (nominal input voltages 24 and 36 V) as well as with ISO 7637-2 (E-mark for automotive) (nominal input voltage 24 V). The power can be switched on and off using an ignition signal on the power connector, and a shutdown delay time after switching off the ignition signal can be adjusted by software.

Flexible I/O

The BC51M supports up to two DisplayPort interfaces with a maximum resolution of 4096 x 2160 each. A multitude of other I/O is available at the front, including two Gigabit Ethernet, one USB 2.0, one HD audio and two slots for legacy serial I/O (RS232), CAN bus, MVB or IBIS.
