DFI CMS103-H420IB Intel LGA 1200 10th Gen Core Thin ITX Motherboard with H420E Chipset, Triple LAN and 15 to 36 V DC Input

A machine-mounted HMI usually has one job for the life of the machine: show the process, take operator input and talk to the PLC. It draws power from the machine’s 24 V rail and has to fit behind a slim panel. The CMS103-H420IB is the H420E build in the DFI CMS103 series of Thin ITX motherboards, aimed at designs like this that need neither remote management nor RAID.

The LGA1200 socket takes 10th Gen Intel Core i9, i7, i5 and i3 processors from four to ten cores, plus two-core Pentium and Celeron parts, as 65 W E or 35 W TE versions. For a fixed HMI application a 35 W Core i3 or Pentium is often enough, and it keeps the cooler low behind the panel. Two DDR4 2933 MHz SO-DIMMs hold up to 64 GB, and Intel UHD Graphics drives internal LVDS and eDP plus two rear DP++ ports, three displays at once.

Three RJ45 ports carry 2.5GbE on Intel I225LM, GbE on an Intel I219V without AMT or vPro, and GbE on an I210AT, enough for a PLC network, a camera and the plant uplink. Four rear USB 3.2 Gen 1 ports and four internal USB 2.0 connect the touch controller and a service port. Two RS-232/422/485 ports, two RS-232 ports and 8-bit DIO sit on internal headers. The M.2 M-key takes an NVMe SSD at PCIe x1 Gen3, the B-key a PCIe or USB module such as a cellular modem, and the E-key Wi-Fi, with two SATA 3.0 ports and a PCIe x16 slot.

The CMS103-H420IB runs from 15 to 36 V DC on a DC jack or 4-pin connector and operates from -5 to 65 °C, with CE, FCC, UKCA, UL, CB and RoHS compliance. For vPro, RAID and USB 3.2 Gen 2, choose CMS103-Q470IB; for Xeon W-1200TE processors, choose CMS103-W480IB.
