Siemens 6ES5390-0UA11 Simatic S5 Text Display

The 6ES5390-0UA11 serves as a text display for SIMATIC S5 automation systems. This unit shows process values and diagnostic messages for operator monitoring. Its rectangular frame measures 232 millimeters in width. The display height reaches 140 millimeters exactly. Depth stays at 85 millimeters. You will find this unit weighs approximately 0.65 kilograms. Therefore, installation requires mounting the unit into a control panel cutout. One 25-pin D-sub connector provides the interface to the PLC.

Physical Layout and Connectors

The front panel features a 2-line alphanumeric LCD display. You will find six membrane keys for operator input below the screen. One 25-pin D-sub port connects to the S5 CPU. Four status LEDs indicate power, communication, and alarm conditions. Four mounting screws secure the unit to the panel cutout.
