DFI EC910-8MM-2GB-WT NXP i.MX 8M Mini DIN Rail PC with 4x COM, 2GB RAM and Extended Temperature

Remote serial gateways in roadside cabinets, substations or water sites tend to sit in enclosures with no heating or cooling. The EC910-8MM-2GB-WT is the 2 GB wide temperature build of the DFI EC900-8MM series, using the taller EC910 case with four serial ports, rated from -40 °C to 70 °C.

Compute is the NXP i.MX 8M Mini, a quad-core Arm Cortex-A53 at up to 1.8 GHz with its own video engine, paired with 2 GB of LPDDR4 on board. That suits protocol conversion, data logging, MQTT or OPC UA gateways and a small local HMI over HDMI. Storage is 8 GB of eMMC with a microSD socket, and the EC910-8MM-2GB-WT runs Yocto 3.3 Linux on kernel 5.10.

The EC910-8MM-2GB-WT has two GbE ports on RJ45, two USB 2.0 Type-A ports and an HDMI output at up to 1920 x 1080 at 60 Hz. Serial is one RS-485 port on a two-pole terminal block, one RS-422 port on a ten-pole terminal block it shares with the 4-bit DIO, and two RS-232 ports on DB9 connectors. Inside are a USB 2.0 header and a USB-C OTG port. An M.2 2230 E key slot takes an optional Wi-Fi and Bluetooth module, an M.2 2242/3042 B key slot with a Nano SIM takes an optional LTE module, and the case has six antenna openings.

Power is 9 to 36 V DC on a terminal block, at 4.6 W idle and 6.4 W maximum, so the EC910-8MM-2GB-WT can share a 12 V or 24 V cabinet supply with PLCs and I/O. It is rated from -40 °C to 70 °C, with vibration testing to IEC 60068-2-64, and DFI lists CE, FCC Class A, UKCA and RoHS compliance. We supply it configured and tested, with the Linux image and any Wi-Fi or LTE module fitted, ready to clip to the rail. Where the software needs more memory, the EC910-8MM-4GB-WT carries 4 GB at the same rating, and the EC900-8MM-4GB-WT is the slimmer case.
