UniOP ePAD05&ePAD06 Industrial HMI

Overall positioning and overview of the product

UniOP ePAD05 and ePAD06 are economical and compact entry-level industrial human-machine interfaces (HMI). As complementary products to the ePAD03/ePAD04 series, they feature small size, high cost-effectiveness, complete support for digital input functions, and are suitable for various small and medium-sized automation equipment and cost sensitive projects. Both models offer a wide temperature expansion version, which can operate in extreme temperature environments and is suitable for both conventional industrial sites and special working conditions; The overall positioning is to replace traditional large-sized, high cost HMIs, achieve device miniaturization and low-cost upgrades, and continue the mature software and hardware architecture and universal functional system of the UniOP series.
