HI 3030 Multi-scale Weight Controller

The HI 3030 is ideal when you need a multi-scale weight controller to act as a front end to a PLC/PAC, PC or DCS system or to operate as a stand-alone instrument for simple control or weight monitoring.  

HI 3030 Weight Controller

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.

The Stand Up 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 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.

Hardy Process ToolboxHardy Process Toolbox

The Hardy Process Toolbox is a set of productivity tools that support industrial weighing functions. Each tool saves time, increases accuracy, improves efficiency or reduces risk in process weighing applications, including WAVERSAVER® to eliminate vibration, C2® electronic calibration and Integrated Technician® to name just a few.

The HI 3030 features the following Toolbox technologies:

WAVERSAVER® Vibration Eliminator
Hardy's WAVERSAVER core technology eliminates the effects that surrounding vibration has on the scale weight signal, providing only true data for fast, accurate weight reading.

C2® (or eCAL) Electronic Calibration
The Hardy C2® (or eCAL as it is known in China) core feature provides quick and easy electronic calibration of a weighing system without the need for heavy test weights.

Hardy's INTEGRATED TECHNICIAN (IT) core feature helps you troubleshoot your weighing system and diagnose problems from the front of the instrument or via the PLC. These tests display system weights, voltages, and pass/fail displays to help isolate a problem to the instrument, cabling, or sensors, helping to reduce maintenance costs.

Embedded Web Server
Access your instrument from any computer browser, easing setup and making diagnostics fast and easy.  Use the Embedded Web Server to set up all parameters from anywhere on the Ethernet network.

Secure Memory Module Stores Configuration Data
Hardy's Secure Memory Module (SMM) uses a proprietary SD card to automatically back up critical weighing system data, and allowing you to transfer it to another like controller in a few minutes.
