SIWAREX WT231 Weighing terminal


The new weighing terminal SIWAREX WT231 combines the powerful weighing module SIWAREX WP231 and a Siemens Touch Panel with application specific user interface in one product.
All settings and parameters for applications in the areas of level measurement and platform scales can be defined via the Touch Panel. The intuitive operation enables the user to perform fast parameter assignment and commissioning.
The integrated weighing module SIWAREX WP231 offers comprehensive diagnostic functions such as checking weight progression or monitoring and reporting of limit values.


As a stand-alone solution, the SIWAREX WT231 can be used independently of the automation solution,
making usage fast and uncomplicated. The RS485 Modbus RTU interface enables a direct integration of the terminal in all conventional controller environments.
