DFI RC300H-CS122 Intel Core i7-9700TE Coffee Lake Railway GPU Computer with 110 V DC Input

As onboard video systems add cameras and heavier analytics models, memory is often the first limit. The RC300H-CS122 is the 32 GB build of the DFI RC300-CS series, a fanless railway computer with an NVIDIA RTX 3000 MXM GPU fitted, four M12 PoE ports and four swappable SSD bays, on a 110 V DC supply.

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 16 GB of DDR4 SO-DIMM, expandable to 64 GB, with TPM 2.0, and Intel UHD 630 graphics drive VGA, HDMI and DP++. The RC300H-CS122 supports Windows 10 IoT Enterprise, as DFI states, and Ubuntu 18.04. The MXM slot on PCIe 3.0 x16 takes modules of up to 115 W without an active fan, and this build ships with an NVIDIA RTX 3000.

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 four 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 RC300H-CS122 is designed to EN 50155 requirements. Power is 110 V DC nominal, 77 to 137.5 V DC, on a six-pin terminal block. It runs from -25 °C to 70 °C with CPU and GPU under 100 W combined, or to 55 °C up to 160 W. It wall mounts. We supply it configured and tested, with SSDs, the OS image and any wireless modules fitted. For 16 GB, see the RC300H-CS111, or the RC300L-CS for 9 to 36 V DC without a GPU.
