SIWAREX WP321 Weighing Module

Brand: Siemens AG
Request Information
Does not ship to United States
SIWAREX WP321 is a versatile and flexible weighing module for the seamless integration of a static scale into the SIMATIC automation environment.

The electronic weighing system is integrated in the SIMATIC ET 200SP series and uses all the features of a modern automation system, such as integrated communication, operator control and monitoring, diagnostic system and configuration tools in the TIA Portal, SIMATIC STEP 7, WinCC flexible and PCS 7.
Features
  • Uniform structure and universal communication through the integration in  I/O SIMATIC ET 200
  • Parameterization of the scale via operator panel, CPU or PC
  • Flexible configuration possibilities in SIMATIC TIA Portal resp. SIMATIC Step7 V5
  • Measuring of weight and force with a resolution of up to ±2 million parts
  • 600 Hz measuring rate (high speed)
  • 100/120 Hz measuring rate (efficient 50/60Hz interference frequency suppression)
  • Scale internal control of freely definable  limit values
  • Easy commissioning  via software  SIWATOOL without SIMATIC knowledge
  • Automatic adjustment without adjustment weights possible
  • Replacement of module without a new adjustment of scale
  • Direct use in ATEX zone 2 possible
  • Various status- und diagnostic information
  • "Ready for use“  sample application
