SIWAREX WT241 Weighing terminal


The weighing terminal SIWAREX WT241 combines the proven quality of two Siemens components into one product: a powerful SIWAREX WP241 weighing module, and a Siemens Touch Panel with an application-specific user interface.

The high-resolution belt scale weighing module convinces with accurate measurement and comprehensive functions. Six independent totalizers provide the conveyed amount of material.. A simulation mode for belt speed and load allows a complete application test - even without a connected scale and speed sensor. Digital in- and outputs can be parameterized flexibly for various functions.
The 4-inch panel with TFT widescreen color display offers a high screen resolution and enables use in very tight spaces without compromising functionality.

As a stand-alone solution, the SIWAREX WT241 can be used independently of the automation solution, making interaction fast and uncomplicated.
