Sintrones VBOX-3630R-M12X Intel 11th Gen Core Railway Computers with M12 LAN and Isolated 24-110V DC Input

Rail projects bring two demands that road vehicles usually do not: a rolling stock power supply, and equipment designed to the electrical and fire standards the fleet is built to. The Sintrones VBOX-3630R-M12X series is a family of railway computers built for that, with an isolated 24 to 110 V DC input and a design to EN 50155 and EN 45545-2 (R25) requirements. The VBOX-3630R-M12X series runs fanless from -40 °C to 70 °C with 0.6 m/s airflow, and Sintrones aims it at fleet management, onboard digital signage and mobile video recording.

Both models share the 11th Gen Core design of the VBOX-3630 series, in a longer 365 x 165 x 55 mm aluminium case weighing 3.8 kg. Two DDR4-3200 SO-DIMM sockets take up to 64 GB, and the integrated graphics drive two HDMI 2.0b ports, a DisplayPort and a single-link DVI-D as four independent displays. Networking is one 2.5GbE and three GbE ports on screw-locking M12 X-coded connectors, with four RS-232/422/485 ports, six digital inputs and four digital outputs. Storage is two 2.5″ SATA bays with RAID 0 and 1 plus M.2 NVMe, and two M.2 Key B sockets with two SIM sockets, an M.2 Key E socket and two mini PCIe slots take optional 5G, LTE, Wi-Fi 6, GPS or CAN modules.

The VBOX-3630R-M12X is the base model, with all four 11th Gen processors on offer: Core i7-1185G7E, i5-1145G7E, i3-1115G4E and Celeron 6305E. The VBOX-3630RP-M12X adds PoE on the four M12 ports with a 60 W total budget, so onboard IP cameras run from the computer, and Sintrones offers it with the Core i7 or i5 only. Both run at 15 W TDP, configurable from 12 W to 28 W, and both use the same isolated rail input.

In practice, the VBOX-3630R-M12X series suits passenger information displays, onboard CCTV recording and fleet telematics on rolling stock. Sintrones lists CE and FCC Class A alongside the EN 50155 and EN 45545-2 (R25) design, with IEC 60068-2-64 and MIL-STD-810G vibration ratings and a MIL-STD-810G shock rating; unlike the road-going models, these builds do not list E-Mark. Each model wall-mounts and has ignition control, a software power-off delay and short-circuit protection, and an optional battery kit gives about 10 minutes of operation.
