HMISTO511 Schneider Electric – Harmony (Magelis) STO 3.4″ Monochrome Touch Panel, Green/Orange/Red Backlight
The Schneider Electric HMISTO511 is a compact 3.4-inch touch panel from the Harmony STO & STU range, originally sold as Magelis STO. Its monochrome STN display has a three-colour backlight (green, orange and red), so operators can see the machine status at a glance: normal running, warning or alarm. It is programmed with Vijeo Designer and fits small machines and local control stations where panel space is limited.
