SIWAREX U

SIWAREX U weighing module

Weighing Module

The SIWAREX U is a versatile weighing module for all simple weighing and force measuring tasks. It is used either centrally in a SIMATIC S7-300 or decentrally via PROFIBUS-DP link to an S7-400, SIMATIC S5 or systems of other manufacturers. The SIWAREX U combined with standard SIMATIC components offers an optimum hardware and software solution. A 1 or 2-channel SIWAREX U used with the SIMATIC CPU 312 C, is a very cost effective, freely programmable weighing system with a total of ten digital inputs and six digital outputs.
