The miniPond 3C weighing controller provides the functions required for trade-approved weight determination in automatic checkweighers. With the fast and accurate weight registration, the weight is assigned to one of the five tolerance zones.
Intuitive operation thanks to clear, application-oriented dialogs and displays. Commissioning, parameterization, remote access and remote maintenance also via a network using the integrated web server or fieldbus. Easy, flexible link-up to a PLC or control system.
Approved weighing controller

Web server functionality
and various communication interfaces
The miniPond 3C can be flexibly integrated into almost any machine and control environment. For this purpose, the weighing controller offers 8 digital I/Os, COM port, Ethernet interface, Modbus protocol and optional fieldbus interfaces such as Profibus, Profinet or EtherNet/IP.
The integrated web server enables access via a browser, for example for setting parameters, for adjustment as well as for functional testing and fault diagnosis. Also data backup, firmware updates and remote maintenance can be carried out comfortably via the web interface.
Remote diagnostics and remote maintenance of devices at other locations via the Internet are also possible (if enabled accordingly). At the same time, the miniPond 3C can also be integrated into Industry 4.0-compliant structures and applications via the fieldbus, for example in condition monitoring applications on the supervisory control level or in the cloud. This makes the miniPond 3C not only a reliable, but also a future-proof weighing controller for automatic scales.
