Import 6dd2920-0at2 — Buy in wholesale FOB from Supplier in China

The 6DD2920-0AT2 is a SIMATIC TDC SM500 I/O module manufactured by Siemens, designed for high-speed data acquisition and signal processing within the SIMATIC TDC (Technology and Drives Control) multi-processor system. This module provides 8 analog inputs with 16-bit resolution and 4 analog outputs with 14-bit resolution, supporting voltage and current signal ranges standard to industrial process control. The unit operates on the TDC backplane bus and is housed in the rugged Siemens form factor for rack-mounted automation cabinets. Huge Technology Automation Co.,Ltd lists this as new inventory with original packaging and a one-year warranty.

The module's analog inputs accept standard ranges of plus-or-minus 10 V, plus-or-minus 5 V, 0 to 10 V, 1 to 5 V, plus-or-minus 20 mA, and 0 to 20 mA, typical for precision control-loop applications in steel rolling mills, paper machines, and large drive systems. Output channels deliver plus-or-minus 10 V or plus-or-minus 20 mA with 14-bit resolution, suitable for setpoint transmission to servo amplifiers and variable-frequency drives. Galvanic isolation between channels and to the backplane is standard for this Siemens series, protecting against ground loops in electrically noisy industrial environments. The module requires configuration through the STEP7 engineering software or TDC-specific CFC/SFC tools.

Primary buyers include system integrators maintaining legacy TDC installations, OEMs building metal-processing lines, and plant engineers upgrading existing multi-processor control racks. The TDC platform remains prevalent in heavy industries where sub-millisecond cycle times and deterministic behaviour are mandatory. Sourcing terms indicate T/T payment, with the supplier stating stock availability and a minimum order quantity of one unit. Buyers should verify firmware compatibility with existing TDC racks and confirm whether configuration cables and documentation are included.

Huge Technology Automation Co.,Ltd is located at Unit 901, Fengrun Financial Holding Group Building B, Site No.1008 Anling Road, Huli District, Xiamen, Fujian Province, 361006, China. The supplier holds a harbor trust tier, which provides basic marketplace verification signals but does not constitute third-party audit certification. The response rate is listed at 0.00 percent with zero average response hours, indicating that direct communication responsiveness has not been established through the platform's tracking mechanisms. Buyers should treat this as an signal to initiate contact early and confirm supplier engagement before relying on stated availability.

The supplier's profile does not disclose years in operation, factory size, revenue figures, or named clientele. The address places the company in Xiamen's Huli District, a developed commercial zone with financial and technology service concentrations. The listing emphasises new inventory, original packaging, and a one-year warranty for the 6DD2920-0AT2 module. No ISO certifications, factory audit reports, or export licence numbers are stated. Buyers are advised to request supplier registration documents, tax identification, and prior transaction references directly.
