Hardy Instruments HI 1756-FC single-feeder control module

Hardy Instruments’ HI 1756-FC is a single-feeder control module that mounts directly into an Allen-Bradley ControlLogix chassis.

It is a closed-loop rate controller used with auger, belt and vibratory-based feeders, converting them from volumetric to gravimetric feeding. This rate controller features 5-point automatic rate calibration, automatic feeder refill and various alarms, including rate tolerance and disturbance utilising the PLC’s rack I/O.

The module was developed with Allen-Bradley ControlLogix add-on profile (AOP). This feature allows the end user to quickly and easily configure the instrument for their application through PLC software on a PC.

It is also fully integrated into the Allen-Bradley integrated architecture builder (IAB). IAB allows the end user to spec out and design their system for optimal productivity, increasing speed and simplifying integration with the click of a mouse. In addition, Hardy Instruments provides sample ladder logic building blocks of code that can easily be inserted into existing code to quickly program the feeder system application.

It also includes the company’s technologies of Waversaver, to eliminate the effects of surrounding vibration for fast, stable weight display, C2 electronic calibration without test weights and Integrated Technician for system diagnostics and troubleshooting.
