Siemens SIWAREX WT241 -Weighing Terminal

June 2021, MARIETTA, GA ~ SIWAREX WT241 weighing terminal combines two proven Siemens components into one product: a powerful SIWAREX WP241 weighing module, and a Siemens Touch Panel with an application-specific user interface.

SIWAREX WT241 offers the following key advantages:

  • Complete solution – no configuration in SIMATIC required

  • Fast and easy commissioning due to intuitive operating concept

  • Stainless steel enclosure permits applications in many diverse environments

  • Integrated terminals for up to 4 load cells (1 … 4 mV/V)

  • Flexible connection to different systems through diverse interfaces - Four digital inputs (24 V DC) - Four digital outputs (24 V DC) - One analog output (0/4 … 20 mA) - RS 485 interface and Modbus RTU

  • High resolution of load cell signal of up to ± 4 million parts

  • Comprehensive diagnostics functions

  • All diagnostic and error messages, as well as all scale parameters, in plain text


The SIWAREX WT241 high-resolution belt scale weighing module provides comprehensive, accurate measurement of conveyed material through six independent totalizers. A simulation mode for belt speed and load allows a complete application test - even without a connected scale and speed sensor. Digital inputs and outputs can be parameterized flexibly for various functions. The 4-inch panel with TFT widescreen color display offers a high screen resolution and accommodates 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.

Typical applications: Belt scale applications


  • Simulation mode, intelligent speed detection, freely parameterizable digital in- and outputs, analog output, Pulse signal for remote totalizers, recovery function

  • High-quality HMI panel - 4-Zoll TFT widescreen display, touchscreen

  • Intuitive user interface

  • Flexible connection to all automation systems, which support Modbus RTU

  • High-quality stainless-steel housing with degree of protection IP65
