Different, yet intuitively familiar for even the least experienced operators. The 920i® HMI indicator/controller is truly the first of its kind to blend revolutionary user interfaces, total flexibility and ultimate processing performance with the simplicity of a basic weight indicator. We have taken the best features from weight instruments, PLCs and computers and added more robust electronics, a crisp graphical display and programmable softkeys. Put it all together inside a virtually indestructible enclosure and you have one of the most advanced HMIs the industry has ever seen. Adding an entirely new dimension in flexibility for solution providers and users alike, the 920i HMI indicator/controller delivers simplified customization at a fraction of the cost of traditional process instrumentation.
From tailored basic weighing to complex process automation, the 920i HMI indicator/controller gives you exactly what you need, exactly the way you want it.
Up to ten different screens can be programmed to change with any given process, while graphic icons and messages show setpoint and function status. The multi-channel display feature shows the weight on an individual scale or a combination of totalized scales. When used in batching/mixing applications, one 920i is capable of handling multiple scales, flow temperature and pulse. It can control hundreds of I/O setpoints—queuing for such things as gates and conveyors. The 920i’s complete database capability stores your important data and files.
For more seamless communication with external devices, use the 920i HMI indicator/controller with USB. It shares the same hardware as the standard 920i, but replaces the PS/2 interface port with a USB interface. Connector types include Standard Type A for hosting, connecting keyboards, printers and memory devices, and Standard Type B for connecting as a device to PCs.
Delivering more features, more programmability and more power for your process, the 920i HMI indicator/controller combines performance-driven circuitry, simplified architecture and customized display features to take your system further.
