Axiomtek tBOX110-APL-MR2 Intel Atom x5-E3940 EN 50155 Railway Computer with M12 LAN and 24-110 V DC Input

Rolling stock supplies vary from fleet to fleet, from 24 V on light rail to 110 V on many mainline trains, and a computer with a narrow input range limits where it can go. The tBOX110-APL-MR2 is the wide-input rail build of the Axiomtek tBOX110 series, a railway computer whose M12 power input Axiomtek’s current datasheet rates at 24 to 110 V DC.

Compute is 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. That suits passenger information, train-to-ground gateways, data logging and CCTV management clients, and the railway computer supports Windows 10 and Ubuntu 20.04.

The rail I/O panel uses locking connectors. Two Intel I210-IT GbE ports sit on M12 A-coded connectors, and four isolated RS-232/422/485 ports with shield grounding and an isolated 4-in/4-out DIO terminal block connect train systems and signals. Two HDMI 1.4b outputs with screw locks, two USB 3.0 ports and audio sit on the front. The tBOX110-APL-MR2 has two full-size Mini Card slots with external SIM sockets for dual LTE or Wi-Fi, and stores data on mSATA or an internal 2.5 inch SATA drive.

The tBOX110-APL-MR2 is EN 50155 and EN 45545-2 certified, meets EN 61373 shock, and runs fanless from -40 to 70 °C with wide-temperature peripherals. Smart ignition control, OCP, OVP, UVP and reverse polarity protection cover the power side, in a 164.1 x 128 x 44.1 mm, 1.02 kg housing. For road vehicles with CAN, the tBOX110-APL-TV is the E-Mark sibling.
