SIEMENS LOGO! TD Text Display 4.3 inch Monochrome LCD Panel 6ED1055-4MH08-0BA3

For LOGO! logic modules that need a clear, readable operator interface without the complexity of a full HMI, the SIEMENS 6ED1055-4MH08-0BA3 text display stands apart. It pairs a 4.3-inch monochrome LCD with a tactile keypad, giving you direct access to parameters, alarms, and process values right at the panel. Unlike generic third-party displays, this unit is engineered specifically for LOGO! 0BA6, 0BA7, and 0BA8 controllers, ensuring seamless communication over the LOGO! TD cable and reliable operation from a 12/24 V DC supply.

Highlights

• 4.3-inch monochrome LCD with adjustable backlight for harsh lighting conditions
• 6 lines x 20 characters – enough to display messages, setpoints, and actual values
• Integrated keypad: 4 function keys, 4 cursor keys, ESC, and ENTER for menu navigation
• Front panel rated IP65, rear IP20 – suitable for washdown areas when properly installed
• Direct compatibility with LOGO! 0BA6, 0BA7, and 0BA8 logic modules

In daily use

Mount the display in a standard 110 x 50 mm cutout, connect it to your LOGO! controller with the dedicated TD cable, and you have a compact operator station. Use the function keys to acknowledge alarms, change setpoints, or toggle bits without opening the control cabinet. The monochrome screen keeps power consumption low – typically 50 mA at 24 V DC – and the wide 10.8–28.8 V DC input range tolerates fluctuating supply voltages. Whether you are commissioning a small machine or retrofitting an existing panel, this display brings essential HMI functionality in a space-saving format.
