720i Programmable Weight Indicator and Controller

The 720i indicator/controller proves its ability to control more processes, more equipment and more information than other basic models. Automate entire systems by commanding batch formulation, inventory management and traceability. Capture and store weight data, link more peripheral equipment and do it all with ease. The 720i design presents an operator keypad in either universal or panel-mount enclosures. Programmable softkeys and operator prompts offer more functionality and control for busy industrial settings.

Utilize the standard configurable batch engine of the 720i Batching version or explore the programming capabilities of the 720i Advanced Truck version in advanced truck mode. Both versions feature local remote capability, allowing multiple indicators to simultaneously display the same data for effortless tracking. Whether used for truck scale operations, data collection, batching or networking, this versatile indicator/controller is an intelligent solution.
