Factory Automation & Embedded Computing Solution – DFI EL620-C | EL620 Series
The DFI EL620-C is a compact, high-reliability industrial motherboard built on the Intel Apollo Lake platform (Celeron N3350). Engineered for 24/7 continuous operation in harsh industrial environments, it delivers stable embedded computing performance for machine control, HMI, and edge intelligence applications.
Where This Product Is Used
- Factory Automation & PLC Integration: Serves as the computing core in automated production lines, coordinating with PLCs (Siemens S7, Mitsubishi Q/FX, Allen-Bradley) via serial and Ethernet interfaces.
- HMI & Operator Panels: Powers touch-screen operator interfaces in CNC machining centers, injection molding machines, and packaging equipment.
- Machine Vision Systems: Provides the processing backbone for inline quality inspection cameras and barcode/OCR reading stations.
- Edge Computing & IoT Gateways: Deployed as an edge node for data acquisition, protocol conversion (Modbus/OPC-UA), and local analytics in smart factory environments.
- Digital Signage & Kiosk Systems: Used in industrial kiosks, self-service terminals, and information display systems requiring fanless, low-maintenance operation.
- Transportation & In-Vehicle Computing: Suitable for vehicle-mounted computing in AGVs, forklifts, and rail applications thanks to wide-voltage input support.

Why Engineers Specify This Model
- Wide Operating Temperature (-20°C ~ +70°C): Handles foundry floors, cold-chain warehouses, and outdoor enclosures without active cooling.
- Fanless-Ready Design: Low TDP Apollo Lake SoC enables fully passive thermal solutions, eliminating fan failure as a maintenance concern.
- Dual Independent Display: VGA + LVDS outputs allow simultaneous operator HMI and supervisory dashboard on separate screens.
- Flexible Serial I/O: RS-232/422/485 software-selectable ports connect directly to legacy PLCs, drives, and sensors without external converters.
- Long Product Lifecycle: DFI guarantees 5+ year supply continuity — critical for OEM machine builders who cannot afford mid-cycle redesigns.
- Compact 3.5-inch Form Factor: Fits into tight control cabinet spaces while delivering full PC-class computing capability.

Application-Specific FAQ
Q: Can the EL620-C communicate directly with a Siemens S7-1200 PLC?
A: Yes. Use the onboard GbE port with PROFINET or S7 TCP/IP protocol libraries (e.g., Snap7). RS-485 port supports Modbus RTU to legacy S7-200 via USS protocol.
Q: Is the EL620-C suitable for a fanless enclosure?
A: Yes. The Intel Celeron N3350’s 6W TDP allows passive cooling via a heatspreader chassis. Verify thermal solution with your enclosure vendor for ambient temperatures above 50°C.
Q: What is the maximum storage capacity?
A: mSATA supports up to 2TB (SATA III), M.2 2242 supports up to 512GB. CFast slot supports industrial CFast cards up to 256GB.
Q: Does it support Windows 10 IoT Enterprise LTSC?
A: Yes. DFI provides validated BSP (Board Support Package) drivers for Windows 10 IoT Enterprise LTSC 2019 and 2021.
Q: Can I use this board in a -40°C cold storage environment?
A: The standard EL620-C is rated to -20°C. For -40°C operation, contact us regarding the extended-temp variant or conformal coating options.
