DFI RC300L-CS Intel Core i7-9700TE Railway Computer with 9-36 V DC and 4x M12 PoE

Not every rail or vehicle installation has a 110 V supply, and not every video recorder needs a discrete GPU. The RC300L-CS is the low-voltage build of the DFI RC300-CS series, a fanless railway computer on a 9 to 36 V DC input with four M12 PoE ports and two swappable SSD bays, without the MXM module.

Compute is the Intel Core i7-9700TE, eight cores at 1.8 GHz with a 35 W TDP, on the Q370 chipset and DFI’s CST51-Q370T board. Memory is 2 x 8 GB of DDR4 SO-DIMM, expandable to 64 GB, with TPM 2.0, and Intel UHD 630 graphics drive VGA, HDMI and DP++. The RC300L-CS supports Windows 10 IoT Enterprise, as DFI states, and Ubuntu 18.04. The i7-8700T and i5-9500TE are listed by DFI as alternatives on request. Without a GPU fitted, the CPU’s own graphics handle the displays.

Networking is two GbE ports on RJ45 plus four GbE ports on M12 X-code with 802.3af PoE at 15.4 W per port, with Intel AMT on the I219LM. Other I/O covers two RS-232/422/485 ports on DB9, 8-bit isolated DI and DO at 2 kV, four USB 3.0 and two USB 2.0 ports and three SIM sockets. Mini PCIe and M.2 slots take Wi-Fi, LTE and 5G modules, with seven SMA antenna holes. Storage is two lockable, swappable 2.5 inch SSD bays and an M.2 2280 M key slot at PCIe x4 or SATA.

Shock and vibration are tested to EN 61373 Category 1, EMC to EN 50121-3-2 and fire protection to EN 45545, and the RC300L-CS is designed to EN 50155 requirements. Power is 12 or 24 V DC nominal, 9 to 36 V DC, on a nine-pin terminal block, and the RC300L-CS runs from -25 °C to 70 °C. DFI publishes a UKCA declaration for this build. It wall mounts. We supply it configured and tested, with SSDs, the OS image and any wireless modules fitted. For an RTX 3000 GPU on 110 V DC, see the RC300H-CS111 or the RC300H-CS-UPS.
