SIWAREX FTC Weighing Module

Brand: Siemens AG
Request Information
Does not ship to Ohio, United States
The SIWAREX FTC (Flexible Technology for Continuous Weighing) weighing module integrated in SIMATIC S7/PCS 7 uses process control system features such as integral communication, diagnostics and configuration tools.

SIWAREX FTC is the optimum solution for demanding continuous weighing applications. Weights can be measured with extreme accuracy in up to three ranges.
Features
  • Uniform structure and universal communication through the integration in the SIMATIC S7 and SIMATIC PCS7
  • Application in the decentralized system concept by connecting to PROFIBUS DP / PROFINET through ET 200M
  • Weight measurement or force to resolutions of 16 million parts
  • Precision (0.5 µV per e)
  • High measuring rate of 10 ms
  • Parameter definable input and output functions
  • Flexible adjustment for various SIMATIC requirements
  • Simple parameter definition with the SIWATOOL FTC program through the RS 232 interface
  • Module exchanging without readjusting the scale is possible
  • Scale progress recording/logging
  • Intrinsically safe load cell supply for Ex-Zone 1 (optional)
  • Application in Ex-Zone 2
  • Extensive diagnostic functions
