Features

• S7-1200 - Weighing Module SIWAREX WP231. SIWAREX WP231 is a versatile weighing module for all simple weighing and force measuring tasks. The compact module is easy to install in the SIMATIC S7-1200 automation system. It can also be operated without a SIMATIC CPU. The module 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 analogue output are connected via the screw connector of the weighing module. A RJ45 connector is used for the Ethernet connection. The primary task of SIWAREX WP231 is the measurement and conversion of sensor voltage into a weight value. Up to three interpolation points are used for the weight calculation. The signal can also be digitally filtered if required. SIWAREX WP231 for connecting load cells, force sensors or torque measuring shafts Uniform design technology and consistent communication in SIMATIC S7-1200 Uniform configuration with TIA Portal Operation without SIMATIC CPU possible Direct connection of an operator panel via Ethernet Direct connection of a remote display via RS 485 interface Four digital inputs and outputs, one analogue output Measurement of weight or force with a high resolution of 1 part per million and an accuracy of 0.05% Simple adjustment of scale using the SIWATOOL V7 program via the Ethernet interface Supports automatic adjustment without adjustment weights Commands available for zeroing and taring Supports replacement of module without renewed adjustment of scale Use in hazardous area zone 2. Applications:. Non-automatic weighing machines Fill level monitoring of silos and bunkers Measuring of crane and cable loads Load measuring for industrial lifts and rolling mills Scales in zone 2 hazardous areas Force measuring, container weighing, platform scales and crane scales
