Touchscreen HMI panel · 5.7 in colour TFT LCD 320 x 240 STU series · Schneider Electric HMISTU855
5.7 in (145 mm) colour touchscreen HMI panel for industrial control and machine interface applications. Schneider Electric HMISTU855 is part of the Harmony STU family and is commonly used where operators need a compact panel with clear local visualisation and touch input.
What this product is for
The Schneider Electric HMISTU855 is a 5.7 in (145 mm) colour touchscreen HMI panel used for operator interface, machine monitoring, and local control in industrial automation systems. It is suited to control panels where a compact display with touch input is required.
Use for
Use for OEM equipment, industrial control panels, packaging machinery, process skids, and manufacturing stations where operators need to view status, alarms, and process screens. It is commonly selected for retrofit or replacement work in Schneider Electric Harmony or Magelis STU installations.
Avoid for
Avoid for applications that require a larger widescreen display, advanced modern graphics, or unsupported communication and software environments without confirming compatibility first. Confirm project software version, mounting space, and environmental requirements before ordering.
Best for
Best for compact industrial HMIs where panel space is limited but a full-colour touchscreen is still needed. This model is a practical fit for electricians, panel builders, and maintenance teams replacing an existing HMISTU855 or specifying a Schneider Electric STU-series interface.
Installed in
Typically installed in industrial control panels, machine doors, operator stations, and automation enclosures in manufacturing and processing environments. Check enclosure cutout, panel depth, and ingress protection requirements as part of the installation review.
Why this product exists
This product provides a local human-machine interface between operators and automated equipment. It gives a clear touchscreen point for viewing process information and entering commands without moving up to a larger IPC or SCADA station.
Compared with similar products
Compared with basic text displays, this unit adds a colour TFT touchscreen for more intuitive operator interaction. Compared with larger HMI panels, the 5.7 in format is commonly chosen where panel real estate is limited. As typical guidance, compact HMIs like this are often preferred for single-machine control rather than plant-wide visualisation. Actual suitability depends on software, communications, and site requirements.
