Axiomtek GOT712S 12.1″ EN 50155 S3 Railway Panel PC with Intel Atom E3845 and 800 Nit LCD

Supply interruptions of a few milliseconds are routine on rolling stock, and an operator screen that restarts each time is a problem in service. The GOT712S is Axiomtek’s 12.1 inch railway panel PC with EN 50155 Class S3 20 ms power interruption protection, an Intel Atom E3845 and an 800 nit sunlight readable XGA touch screen, and it is compliant with EN 50155.

The Intel Atom E3845 runs at up to 1.91 GHz with 4 GB of onboard DDR3L memory and 16 GB of onboard flash, with the second PCI Express Mini Card slot used for mSATA storage, which suits train operator status displays, speed, temperature and security monitoring and fleet management. Windows 10 IoT, Windows 10 or 7 and WES7 are available as optional installs. The display is an XGA LCD at 1024 x 768 with an 800 nit LED backlight, 160° viewing angles and auto-dimming, under 5-wire resistive touch that works with gloves.

I/O is built for rail wiring: two isolated M12 X-coded Gigabit Ethernet ports, one M12 A-coded connector carrying two USB 2.0 ports and two isolated M12 A-coded RS-232/422/485 ports, plus an isolated DB9 CANbus port and a terminal-block DIO with six inputs and two outputs, all isolated to 1.5 kV. A DB15 connector carries line-in, mic-in and speaker-out or line-out, and optional 3G+GPS and Wi-Fi kits are available. The GOT712-837 is the same 12.1 inch design without Class S3 protection, and the GOT715S brings Class S3 protection to a 15 inch screen.

Power is a typical 24 to 110 V DC on an M12 A-coded connector. The GOT712S is fanless, operates from -40 °C to 70 °C at 10 to 95% humidity, and pairs an IP65 aluminium front bezel with IP40 rear protection. It is compliant with EN 50121-3-2, EN 61373 and EN 45545-2 and carries CE and FCC Class A marks. It measures 330 x 245 x 61.5 mm, weighs 2.95 kg and fits a wall mount or a VESA 100 mount.
