The TM SIWAREX WP521 ST and WP522 ST (ST = Standard) are highly versatile weighing modules designed for the SIMATIC S7-1500 Advanced Controller family. These electronic weighing systems facilitate the seamless integration of simple weighing applications, including platform or hopper scales, into the S7-1500 automation environment. This integration capability enhances the overall efficiency and automation of weighing processes within industrial settings.

The SIWAREX WP231 is a versatile weighing module that is legal for trade and suitable for a wide range of simple weighing and force measuring tasks. This compact module is designed for easy installation within the SIMATIC S7-1200 automation system. Additionally, it is capable of standalone operation without a SIMATIC CPU, providing flexibility in its application. 

SIWAREX DB offers advanced diagnostic and monitoring capabilities when used alongside SIWAREX WP weighing electronics. The individual channel monitoring helps identify specific error states like wire breaks and overloads. Additionally, connecting SIWAREX DB to a SIWAREX WP electronic weighing system ensures smooth integration into the SIMATIC world.

Ex interface SIWAREX IS is designed for use with SIWAREX weighing modules, incorporating six safety barriers and obtaining relevant technical approvals. Importantly, it must be installed outside the potentially explosive area, typically inside the control cabinet, ideally under the electronic weighing system, and fixed using a 35 mm mounting rail. The SIWAREX IS minimally interferes with the load cell signal, making it suitable for scales requiring official calibration. Connection is facilitated at the front using two clamp-type plugs, with a separate screw terminal provided for the equipotential bonding conductor (EBC).
