SIWAREX WP251 is a compact technology module in the SIMATIC S7-1200, and communicates directly via the system bus with the SIMATIC S7-1200 controller.

The compact weighing module with a width of 70 mm (2.76 inches) is installed using a mounting rail. This is extremely user-friendly.

The connections for the power supply, the load cells, the RS-485 port, the digital inputs/outputs, and the analog output are located on removable screw connector blocks. An RJ45 port is available for the Ethernet connection (SIWATOOL and Modbus TCP/IP).
