The SIWAREX U is a versatile weighing module for all simple weighing and force measuring tasks. It is either used centrally in a SIMATIC S7-300 or M7 or decentrally linked via PROFIBUS-DP to an S7-400, SIMATIC S5 or systems of other manufacturers.

Examples of its uses include filling levels in storage silos and containers for monitoring crane loads, measuring conveyor belt loads, and as an overload protection for industrial lifts or mill trains. That means, anywhere, where weights need to be recorded and transferred to the automation system for processing as quickly as possible, with no bias and without the need for an additional interface.

With SIWAREX U and further standard components from the SIMATIC range, we can offer you the optimum hardware and software environment.

If, for example, a 1 or 2-channel SIWAREX U is used with the SIMATIC CPU 312 IFM, the result is a very cost effective, freely programmable weighing system with a total of ten digital inputs and six digital outputs.

SIWAREX U at a glance:

• Integration in SIMATIC S7 / M7 / PCS 7
