MEN – Fanless and maintenance-free PC ideal for memory-intensive applications in trains, buses or commercial vehicles

MEN's latest box PC, BL51E, is equipped with an Intel Atom E3950 with 1.6 GHz, and offers CPU performance scalability by a variety of other dual/quad-core processors from the Intel Atom E3900 series. With 8GB of DDR3 SDRAM memory, a backward-accessible SD card and a SATA HDD/SSD shuttle, as well as an integrated eMMC memory, the box PC has the necessary storage capacity, e.g. for entertainment servers or video surveillance systems. The device is typically used in the transportation sector, such as trains, buses or commercial vehicles, and can be used to provide wireless on-board functions like an internet connection for passengers, or to localize the vehicle. A variety of I/O functions and options smoothly connect the PC to the IoT. The application provides four PCI Express mini-card slots with two micro SIM slots and dual SIM support. This provides maximum flexibility for implementing mobile service standards with up to 4G LTE or WLAN. There is also a GNSS interface for GPS or GLONASS. Two display port interfaces with a maximum resolution of 4K, four Gigabit Ethernet, two of them with PoE support, two USB 2.0 ports, a serial I/O port and a CAN bus interface complete the I/O functions. The complete system is designed for fanless operation in a temperature range of -40C to +85C. Thanks to the integrated 30W/24VDC wide-range power supply unit, the box PC complies with railway standard EN 50155 and with ISO 7637-2.
