Product Overview
The SIWAREX U is a single-channel weighing module for SIMATIC S7-300 and ET 200M systems, designed for platform or hopper scales using analog full-bridge load cells.
One weighing channel evaluates compatible analog load cells with a 1 to 4 mV/V signal range. The module operates in supported S7-300 or ET 200M stations and exchanges process data through the backplane bus. An integrated RS 232 connection supports commissioning and service access with the appropriate engineering tools.
