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.

The Rice Lake Weighing Systems 920i digital weight indicator has been an extremely successful indicator. It’s been utilized in thousands of different applications with accurate and reliable results. But as we all know things change and technology improves. So Rice Lake is making a few updates to the 920i which should allow it to continue to be a great choice for your scale needs for years to come.

To make the 920i programmable weight indicator even more robust and further extend its life, Rice Lake Weighing Systems is now manufacturing the 920i with enhanced display and CPU boards. These changes offer several benefits and are essential to ensure availability of components needed to continue manufacturing the 920i in the future.

As of February 1, 2018, Rice Lake began manufacturing the 920i with a technologically improved LED backlight display. While this change may go unnoticed, it affects the replacement part process.

If a 920i was built prior to February 1, 2018, and needs a replacement display, Rice Lake recommends replacing the old fluorescent backlight display with a new LED backlight display.

As of June, Rice Lake will begin implementing a new CPU board in the 920i. This updated board (PN 186272, blue in color for easy identification) is compatible with firmware version 4.0 and above, and offers the following benefits:

Call the sales / service team at Central Carolina Scale (919) 776-7737 to obtain the 920i indicators and replacement parts that you need. For replacement parts, you will want to have indicator serial numbers handy along with the date that you purchased the indicator.
