LOGO! TD Text Display — 6ED1055-4MH00-0BA1
The Siemens 6ED1055-4MH00-0BA1 is a LOGO! TD Text Display, part of the LOGO! family, designed for use with LOGO! 8 and higher base modules. It provides a 6-line FSTN (Film Compensated Super-Twisted Nematic) display with LED backlight and three selectable background colors, giving the operator clear readout of process variables, alarms, and system messages directly on the control panel. Rated for 12/24 V AC/DC supply, it draws a typical power loss of 1.8 W — negligible for the overall power budget of a LOGO! system. The unit measures 128.2 mm wide by 86 mm high by 38.7 mm deep, fitting into a standard panel cutout. It includes two Ethernet ports for connection to the LOGO! 8 base module, allowing the display to be mounted remotely from the controller if needed. The display supports up to 20 characters per line across 6 lines, with system keys for navigation — no alphanumeric keyboard is built in, so all text entry is handled through the LOGO! programming software.
Approvals include CE, UL, FM, KC, and ABS (American Bureau of Shipping), covering industrial, marine, and North American regulatory requirements. The ABS approval is notable — it allows the display to be used in shipboard automation panels where maritime classification is mandatory.
Integration with LOGO! 8
This display connects directly to the LOGO! 8 base module via the integrated Ethernet ports — no separate communication module is needed. It mounts in a panel cutout and connects to the controller through a standard Ethernet cable, supporting distances up to the cable length limit for the installation. The IP65 front rating means the display can be mounted on the enclosure door without additional sealing gaskets, as long as the cutout and mounting screws are properly torqued.
