Siemens LOGO! TD Text Display 6-Line for LOGO! 8, Ethernet, IP65, 4 Function Keys, 12/24V DC, 6ED1055-4MH08-0BA1

On a busy packaging line, an operator needs to adjust a setpoint without walking back to the control cabinet. The Siemens LOGO! TD Text Display brings that control right to the machine. This 6-line, 20-character monochrome LCD panel connects directly to any LOGO! 8 logic module via Ethernet, showing process values, I/O states, bar graphs, and custom messages. The backlight switches between white, orange, and red to signal normal operation, warnings, or alarms at a glance. Four programmable function keys let operators acknowledge faults, change parameters, or navigate menus without extra hardware. With IP65 protection on the front, it withstands washdowns and dusty environments, while the compact panel-mount design fits standard cutouts. Powered by 12/24V DC and drawing just 3 W, it is an energy-efficient addition to any automation setup. Programming is done entirely in LOGO! Soft Comfort, so no extra software is needed.
