CLP storage medium — function and fit
Siemens 6GK1900-0UB00-0AA0 is a SCALANCE CLP removable storage medium with 2048 Mibyte capacity, for simple device replacement in SCALANCE devices with a CLP slot. The card measures 32 mm deep, 17.5 mm wide, and 7 mm high — dwarfs any full-size SD card. The -40 to +85 °C operating range means it survives inside a panel that bakes in summer or freezes overnight. IP20 rated and no conformal coating — keep it clean, no rinsing. Swap it in, wire nothing, and the SCALANCE picks up the config.
Sourcing and production status
The listed MTBF of 343 a is high for a storage component; you won't be swapping this out every few years. It's a fit-and-forget part if the slot stays populated.
