Weight Controller monitors and controls up to 4 scales.
Press Release Summary:
Multi-scale Model HI 3030 can act as front end to PLC, PC, or DCS system for applications such as batching, filling, dispensing, and check weighing, or as stand-alone unit for control or weight monitoring. Up to 16 controllers can be connected through single interface for total of 64 scales. With flexible I/O mapping and 12 independent internal setpoints, users can direct alarms or enunciators to local output or to any point on plant network.
Original Press Release:
Multi-scale Weight Controller
The Hardy Instruments HI 3030 Weight Controller is a flexible, world-class weight controller that can monitor and control up to four scales simultaneously.
The Multi-scale weight controller can act as a front end to a PLC, PC or DCS system for applications such as level, batching, filling, dispensing, and check weighing, or as a stand alone for simple control or weight monitoring.
NETWORKING
As a bridge to a PLC, its four scales can share one network connection, whether it's DeviceNet, ControlNet, Ethernet/IP, Allen-Bradley Remote I/O, or Profibus. You can also link additional HI 3030s with their multiple scales and share the same network connection. Just like the other Series 3000 products, you can configure or monitor the HI 3030 operating using your Palm OS PDA, web browser, or network interface.
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. You could buy two HI 3030s, each with four scale inputs, and tie them together with the built-in Ethernet communications. Bring all eight scales back to your PLC using just one of the HI 3030s, or with an optional ControlNet, DeviceNet, Profibus, or Allen-Bradley Remote I/O 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.
THE STAND-ALONE SOLUTION
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.
COMPLETE FLEXIBILITY
With the flexible I/O mapping and twelve independent internal setpoints in the HI 3030, you can direct 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. You can even use a Palm PDA as a "virtual" local keypad and display via its standard IR port.
INTEGRATED TECHNICIAN®
The HI 3030's INTEGRATED TECHNICIAN®, in conjunction with an IT Junction Box, provides built-in system diagnostics that allow you to troubleshoot and diagnose your weighing system right from its front panel, a PDA, your intranet or the internet. You can read individual load sensor voltages and weights, make comparisons, and isolate individual system components for quick and easy troubleshooting.
