The Siemens 6GT2790-0DD01 is a SIMATIC RTLS accessory — a charging station designed to simultaneously charge up to 10 RTLS transponders in the US housing types (RTLS4083T and RTLS4040T) via spring contacts with a magnetic retainer. It accepts a 100-240 V AC input through a C13 power cord and outputs 5 V DC at up to 6000 mA to the charging bay. The unit is built as a desktop device in a plastic enclosure (PC 10 GF) and can also be wall-mounted using the included power supply. Its Ti gray color and compact footprint (298.4 mm wide, 179 mm deep, 81.5 mm high) suit it for placement on a workbench or inside a cabinet near the tag storage area.
The 5 V DC, 6000 mA supply means the station can deliver full charging current to all 10 bays simultaneously — each tag gets roughly 600 mA if the load is balanced, which is typical for charging Li-ion RTLS tags from flat. If you're sourcing this for a line that runs multiple shifts, the 6 A draw from the external power brick means the station itself needs no internal PSU; the brick is included. IP00 protection class means the station has no ingress protection — it's intended for indoor, dry, dust-controlled environments only. Not for washdown areas or outdoor kiosks. The operating, storage, and transport temperature range is identical: -10 to +50 °C. That's a typical indoor factory floor range; if your tag storage area sees ambient above 50 °C (e.g., near a furnace line), you'll need to relocate the station or provide local cooling.
Because this is a specialized RTLS accessory — not a general-purpose PLC or drive — it is not commonly stocked in high volume by broad-line distributors. The typical sourcing path is a quoted-to-order RFQ through an industrial automation distributor that handles Siemens SIMATIC RTLS line items. Expect to specify the quantity and confirm the included power cord variant (C13, US plug) when placing the order.
Integration notes
The 11 electrical connections consist of 1 P1J barrel jack (ID 2.1 x OD 5.5 mm) for the 5 V DC input and 10 spring-contact charging points for the transponders. There is no fieldbus, Ethernet, or signaling interface — this is a pure power-delivery station. No configuration or software setup is required; plug in the power supply, insert the tags, and the magnetic retainers hold them in place against the contacts. The station is designed specifically for US housing variants of RTLS4083T and RTLS4040T tags. If your tag fleet uses the EU or other regional housing, the spring-contact geometry and magnetic retainer alignment will not match — verify the tag housing type before committing the BOM line.
