TDE text display module, 6-line FSTN with 20 characters per line, conformal-coated variant, 12/24 V DC and 24 V AC supply, -40…70 °C, IP65 at the front, 128.2 × 86 × 38.7 mm, based on 6ED1055-4MH08-0BA0.","salesMarkdown":"The Siemens 6AG1055-4MH08-2BA0 is the SIPLUS variant of the LOGO! TDE text display, listed as the current-production spare-part build based on the 6ED1055-4MH08-0BA0 standard unit, with conformal coating added for harsh environments. It belongs to the LOGO! product line and is specified as usable with LOGO! 8 and higher, so it mounts onto a LOGO! 8 base. The 6-line display is not listed for older generations. The front carries an IP65 rating against the panel face, and the housing is plastic with no wall-mount option — it is designed as a panel-cutout display, not a free-standing module. ## Temperature, altitude and condensation envelope Cold-restart floor is 0 °C, and condensation or frost is permitted at restart only — commissioning under active condensation is not allowed, so a heater or enclosure climate strategy is still required if the panel is started up while wet. Installation altitude is rated to 5 000 m, with stepped derating per the barometric-pressure table: -40…70 °C to 2 000 m, then to 3 500 m, then to 5 000 m. ## Display, supply and footprint The display is a 6-line FSTN panel with 20 characters per line and an LED backlight — the same UI surface as the standard TDE, so existing LOGO! 8 message texts migrate without rework. Supply voltage is AC/DC, accepting 12 V DC, 12/24 V DC and 24 V AC, with a typical power loss of 1.8 W at 24 V DC — small enough that a LOGO! 8 base power budget will accept the second display without re-sizing the supply. Footprint is 128.2 mm wide × 86 mm high × 38.7 mm deep, matching the standard LOGO! TDE cutout for a direct mechanical swap where a harsh-environment upgrade is needed. The unit ships singly and the part carries no configurable system keys or alphanumeric keyboard, which keeps operator input limited to the cursor keys on the base LOGO! 8 unit. Because the part is the SIPLUS conformal-coated build of an active standard product, the cleanest cross-reference on a worn or failed display is to the 6ED1055-4MH08-0BA0 standard TDE, and the cleanest upgrade path in the opposite direction is to this 6AG1055-4MH08-2BA0 where the cabinet environment demands it.","metaTitle":"SIPLUS LOGO!
