Product Details

S7-1200 - Weighing Module SIWAREX WP231

SIWAREX WP231 is a versatile weighing module for all simple weighing and force measuring tasks. The compact module is easy to install in the SIMATIC S7-1200 automation system. It can also be operated without a SIMATIC CPU.
The module allows direct connection to S7-1200 components via a sliding connector. The rail mounting of the 70 mm (2.76 inch) 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 the screw connector of the weighing module. A 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.
