Axiomtek tBOX110 Intel Atom x5-E3940 EN 50155 Railway Computers with EN 45545-2

Trains and road vehicles ask similar things of a computer, but they differ on power, connectors and certification. Rolling stock wants M12 connectors, isolated I/O and EN 50155, while buses and trucks want ignition control and E-Mark. The Axiomtek tBOX110 series covers both with railway computers that share one compact, fanless design and differ in their I/O panel and power input.

Every tBOX110 uses the Intel Atom x5-E3940, a quad-core Apollo Lake processor at 1.6 GHz with a 9.5 W TDP, with one DDR3L SO-DIMM slot taking up to 8GB. Two HDMI 1.4b outputs with screw locks, two USB 3.0 ports and mic-in and line-out audio sit on the front. Two full-size Mini Card slots, each with an external SIM socket, take LTE, Wi-Fi or an mSATA drive, alongside an internal 2.5 inch SATA bay. Smart ignition, OCP, OVP, UVP and reverse polarity protection are standard, and TPM 2.0 is supported.

Three models are listed, and the choice follows the vehicle type and its supply voltage. The tBOX110-APL-MR2 has two M12 A-coded GbE ports, four isolated RS-232/422/485 ports, isolated 4-in/4-out DIO and an M12 power input that Axiomtek now rates at 24 to 110 V DC, with EN 50155 and EN 45545-2 certification. The tBOX110-APL-MR1 shares that rail I/O with a 24 V DC M12 input. The tBOX110-APL-TV is the road vehicle model, with two RJ-45 GbE ports, two RS-232/422/485 ports, two isolated CAN 2.0 A/B ports with SocketCAN, DB9 DIO, a 9 to 36 V DC terminal block input and E-Mark certification.

All tBOX110 railway computers run fanless from -40 to 70 °C with wide-temperature peripherals and measure 164.1 x 128 x 44.1 mm at 1.02 kg. They are tested to 3 Grms vibration with SSD and MIL-STD-810G Method 514.6C-VI Category 4, and the rail models meet EN 61373 shock. Windows 10 and Ubuntu 20.04 are supported, with wall mounting as standard and DIN-rail and anti-vibration kits available. Typical uses include passenger information and counting on trains and trams, train-to-ground and bus telematics gateways, CCTV management clients and depot equipment, where one shared design across rail and road fleets keeps software images, spares and engineering familiarity in common.
