SIWAREX WP231 is a compact technology module in SIMATIC S7-1200 and 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 analog output are connected via the screw connector of the weighing module. A RJ45 connector is used for the Ethernet connection.
