The Siemens 6GT2790-0DD02 is a SIMATIC RTLS accessory charging station in a Ti gray plastic enclosure (PC 10 GF). It is designed as a desktop unit or for wall mounting, with an integrated power supply unit. Its job is parallel charging of up to 10 RTLS4083T, Plus, or ETSI transponders via spring contacts with a magnetic retainer — meaning you drop the tags into the station and they seat and charge without a cable. The 10 charging contacts plus the power jack give it 11 electrical connections total. The supply input is 100–240 VAC with a CEE 7/7 power plug, stepped down to 5 VDC internally. Maximum current draw is 6000 mA, so the station can push a full charge current to all ten tags simultaneously.
This part carries an NRND (Not Recommended for New Designs) lifecycle status. Siemens continues to support existing installations and manufacture it for spares.
The IP00 protection class means this is an indoor, clean-environment unit only — no dust or moisture ingress protection. It is intended for a desk, shelf, or wall inside a conditioned space, not a factory floor or washdown area. Dimensions are 298.4 mm wide, 180.6 mm deep, and 83.2 mm high — a compact footprint that fits on a standard workbench or under a monitor arm. The plastic enclosure is PC 10 GF (polycarbonate, 10% glass-fiber), which gives it reasonable impact resistance for a benchtop device. Operating, storage, and transport temperature range is identical at -10 to +50 °C, so no special climate handling is needed for shipping or storage as long as you stay within that band.
