AutomationDirect EA1-S3MLW Operator Interface Panel

The EA1-S3MLW is a 3-inch C-more Micro HMI panel featuring a monochrome STN LCD with a resistive single-touch surface and a high-contrast white LED backlight, delivering 128 × 64 pixel graphics for compact operator interfaces. It provides a single serial port for communication with AutomationDirect PLCs (RJ12 connection), enabling straightforward PLC–human interface integration on small machines and panel-mounted equipment. The model, together with the EA1-S3MLW-N, supports five background colors—White, Pink1, Pink2, Pink3, and Red—allowing quick visual customization to suit different control panels or environments. Power delivery is designed to occur through the panel’s RJ12 serial connection when used with compatible AutomationDirect PLCs. Listed in AutomationDirect’s catalog as a retired HMI option, this panel is geared toward lightweight, space-constrained applications where a simple, reliable touchscreen display for basic status readouts, numeric input, and PLC control suffices.
