Product Details

Siemens Weighing Module

The Siemens weighing module is a versatile weighing module for all the simple weighing and force measuring tasks. This compact module is easy to install in the SIMATIC S7-1200 automation system. It can also be operated without a SIMATIC CPU. This module allows direct connection to S7-1200 components via a sliding connector. The rail mounting of the 70mm (2.76in) wide weighing module means that it is extremely easy to mount/wire. The power supply, load cells, the RS 485, digital input/outputs and the analogue output are connected via a screw connector of the weighing module. An RJ45 connector is used for the Ethernet connection. The primary task of SIWAREX WP231 is the measurement and conversion of sensor voltage into a weight value. Up to three interpolation points are used for the weight calculation. The signal can also be digitally filtered if required.
