ADLINK SP2-EHL Fanless Tablet Selection and Configuration Guide

ADLINK SP2-EHL series fanless tablet selection and deployment guide

In application scenarios such as industrial automation, machine vision, intelligent logistics, and human-machine interface (HMI), traditional commercial tablets are often unable to cope with harsh dust, vibration, and wide temperature environments. ADLINK SP2-EHL series open panel computer, based on Intel Atom ®  The x6000E series processor (Elkhart Lake) provides a variety of sizes from 7 inches to 21.5 inches, fan free design, wide voltage input (9-36V optional), high ESD tolerance and flexible function module expansion, providing a reliable and economical integrated solution for industrial edge computing and device control. This article is aimed at system integration and equipment maintenance engineers, and elaborates on the key points of application deployment for the SP2-EHL series from dimensions such as model analysis, hardware selection, key interface configuration, functional module expansion, power and PoE deployment, and system software support.

Product Series Overview and Model Analysis

The SP2-EHL series is a new generation of fanless industrial tablets launched by ADLINK, featuring an open frame design that facilitates integration into various cabinets, devices, or self-service terminals. Its core advantages lie in:

Processor platform: Intel Atom ®  The x6000E series (Elkhart Lake) offers a multi-level selection from dual core to quad core (J6412, x6211E, x6413E, x6425E), balancing performance and power consumption.

Display size: Covering 7 inches (1024 × 600), 10.1 inches (1280 × 800), 15.6 inches (1920 × 1080), and 21.5 inches (1920 × 1080), suitable for different visual distances and space requirements.

Fanless cooling: The entire series of fanless designs rely on natural convection of cooling fins to prevent dust inhalation and improve MTBF (mean time between failures).

Functional module design: Reserved functional module slots on the front panel, which can quickly expand USB, serial port, GPIO and other I/O without disassembling the device.

Wide voltage power supply: default 12V DC, optional 9-36V wide voltage input, suitable for unstable power supply environments such as vehicles, ships, engineering machinery, etc.

Optional PoE power supply: Supports 60W PoE (Power over Ethernet) power supply through an external module, and only requires one Ethernet cable to achieve power supply and data transmission, simplifying wiring.
