Siemens WP231 Series PLC Expansion Module for Use with S7-1200 Series, Digital, Analogue, Digital

Add a precision weight and force measurement function to your PLC with the SIWAREX WP231 weighing module from Siemens. It's a robust device that's ideal for applications such as non-automatic weighing machines, fill level monitoring of silos and load measuring for industrial lifts. Ethernet and RS485 interfaces allow integration into different control systems via the Modbus protocol, meaning you can operate this module with or without a Siemens SIMATIC S7-1200 PLC. Up to three interpolation points are used to calculate weight, offering an error limit of 0.05% and a high resolution of 1ppm, for reliable accuracy.

• 10 millisecond measuring rate for rapid results
• User-friendly SIWATOOL V7 programme enables scale adjustment with no need for automation engineering skills
• Extensive diagnostic functions simplify maintenance, for reduced downtime and increased productivity

As this device is rail-mounted, installation is straightforward. The power supply, load cells, RS485 and all inputs/outputs (digital and analogue) are connected using the secure screw terminal method so contacts are robust and reliable.
