Import 6dd1682-0bc0 — Buy in wholesale FOB from Supplier in China

The 6DD1682-0BC0 is a SIMATIC TDC signal conditioning board manufactured by Siemens, designed for use within the SIMADYN D and SIMATIC TDC control systems. This board converts and isolates analog and digital signals between the processor board and external field devices, operating with a 24 V DC supply voltage and handling standard industrial signal ranges. Huge Technology Automation Co.,Ltd lists this unit as new inventory with original packaging, indicating it is an unused component rather than refurbished or surplus stock. The board fits within the standard SIMATIC TDC subrack architecture and communicates via the backplane bus to the central processing modules.

The 6DD1682-0BC0 employs optocoupler isolation for digital channels and transformer isolation for analog paths, providing noise immunity in electrically harsh industrial environments. Typical input impedance for voltage channels is 10 MΩ or greater, with current loop inputs presenting 250 Ω standard burden. The board supports 16 digital inputs and 16 digital outputs in its standard configuration, with response times under 1 ms for digital switching. Siemens specifies operating temperatures from 0 to 60 °C with relative humidity up to 95 percent non-condensing, though exact environmental ratings for this specific revision should be confirmed against the factory datasheet. Color and finish depend on the material batch, consistent with Siemens industrial plastic housing standards in charcoal or similar neutral tones.

Primary applications include steel mill automation, turbine control, paper machine drives, and other continuous-process industries where SIMATIC TDC systems remain in service. Buyers are typically maintenance engineers at heavy industrial facilities, system integrators supporting legacy Siemens installations, or spare parts procurement specialists for power generation and metallurgy sectors. Huge Technology Automation offers the unit with a one-year warranty and lists it as in stock, though buyers should verify current availability directly given the zero percent response rate indicator on the seller profile. Payment is accepted via T/T transfer, and the listed MOQ is one piece, making this accessible for single-unit replacement needs.

Huge Technology Automation Co.,Ltd operates from Unit 901, Fengrun Financial Holding Group Building B, at 1008 Anling Road in Huli District, Xiamen, Fujian Province, China. The company holds a harbor trust tier classification on the marketplace, and its response rate shows 0.00 percent with zero average response hours recorded, which buyers should note when planning procurement timelines. The business address places it within Xiamen's technology corridor, though no information about facility size, manufacturing capability, or warehouse capacity is stated in the available profile.

The supplier's visible activity centers on new and original Siemens industrial automation components, specifically targeting the SIMATIC and SIMADYN product lines for legacy system support. No information is provided about company founding date, employee count, annual revenue, or specific client industries served. The listing does not indicate any third-party verifications, ISO certifications, or membership in trade associations. Buyers should conduct independent due diligence on company registration and financial standing before committing to large orders, particularly given the absence of recent response activity.
