BC51M - Rugged Industrial Box PC with Intel Atom Processor E3900 Series

For Onboard Applications

The BC51M is a maintenance-free box computer that has been designed for use in vehicles, e.g. in trains, commercial vehicles, mobile machines or airplanes 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 on-board 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 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 BC51M comes with an integrated 30W wide-range DC/DC converter compliant with EN 50155 (nominal input voltages 24 and 36 V) and prepared for 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.

Long-Term Available and Future-Safe

Long-term availability until 2027 ensures an extended product life and future-safety.
