Product details

SIPLUS LOGO! TDE — extended-temperature operator panel

The 6AG1055-4MH08-2BA1 is a SIPLUS variant of the LOGO! TDE, built on the standard 6ED1055-4MH08-0BA1 but with conformal coating and a widened temperature range of -40 to +70 °C (start-up from -20 °C). That means it handles cold storage, unheated enclosures, or hot cabinet summers without derating — the coating also shrugs off condensation, diesel mist, and oil droplets in the air.

Power draw is 1.8 W typical from a 24 V DC supply, so it won't strain a shared power budget in a small cabinet. The two Ethernet ports connect directly to LOGO! 8 and higher for programming via LOGO! Soft Comfort V8 — no extra gateway needed.

Frequently asked questions

Is 6AG1055-4MH08-2BA1 compatible with LOGO! 8?

Yes, it is designed for use with LOGO! 8 and higher, programmed via LOGO! Soft Comfort V8. The two Ethernet ports connect directly to the LOGO! base module.
