Multi-scale weight controller
The HI 3030 is a flexible weight controller that can monitor and control up to four scales simultaneously. It can act as a front end to a PLC/PAC, PC or DCS system or operate as a stand-alone instrument for simple control or weight monitoring. Common applications for the HI 3030 include leveling, batching, filling, dispensing, and check weighing. You can easily configure or monitor the HI 3030 operations using the front panel, a web browser or network interface.
As a bridge to a PLC/PAC, up to four scales can share one network connection, whether it’s DeviceNet, ControlNet, Ethernet/IP, or Profibus. You can also link additional HI 3030s with their multiple scales and share the same network connection.
The PLC Solution
So let’s say you have eight storage tanks and you would like to monitor and control the weight in each of the tanks using your PLC/PAC. You could buy two HI 3030s, each with four scale inputs, and tie them together with the built-in Ethernet communications. Then bring the outputs from all eight scales back to your PLC/PAC using just one of the HI 3030s, or with an optional ControlNet, DeviceNet, Profibus, or EtherNet/IP network card.
Need more than eight storage tanks? OK! You can connect up to 16 controllers, for a total of 64 scales, through that same single interface. You save wiring, time and money.
So let’s again take the example of the eight storage tanks, but this time you wish to control tank weights outside of the PLC. No problem! With or without a connection to the PLC, you can set up the HI 3030 to automatically refill each of the storage vessels when they get to their individual “low” levels. Now, you can also save on programming costs.
With flexible I/O mapping and twelve independent internal setpoints, you can direct the HI 3030 alarms or enunciators to a local output or to any point on the plant network. You can even have an alarm emailed directly to you! Don’t need a display or keypad on the controller? Use the Blind Remote HI 3030R, and control or configure the unit via your web browser or your local network.
