Siemens, Nuremberg, Germany, has introduced Siwarex DB, a digital junction box with robust field housing in IP66 protection, which can be easily integrated into Simatic environments. The Siwarex DB extends the Siemens weighing technology portfolio and through its seamless networking ensures that individual analogue load cells can now be acquired and evaluated more comprehensively than ever before. They can be used both for the targeted monitoring of weighing processes and for extended diagnostics. Any error messages are displayed centrally on the Simatic controller and the HMI.

The seamless connection of the control unit and Siwarex WP weighing electronics enables immediate diagnostics of the load cells. This makes servicing quicker and easier, and minimises downtimes. In order to prevent inaccurate or incorrect measurements, the weighing modules must operate precisely. An essential requirement for this is complete transparency regarding the status of the devices. Siwarex DB offers the option of connecting the scales with up to four load cells, thus providing the required flexibility in plant planning. A new feature is the single-channel monitoring of each connected load cell. For example, error conditions such as wire break or overload can be detected and removed specifically, making servicing easier. Siwarex DB can also be used in a wide range of applications in the field of industrial weighing technology, such as level monitoring, silo or container weighing. www.siemens.com
 

The Siwarex DB digital junction box is simple to retrofit to existing plants; it has the same dimensions as the earlier Siwarex JB and can be connected to the same cables
