Single-Feeder Control Module Is A Closed-Loop Rate Controller

Feb. 24, 2010

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 true five-point automatic rate calibration, automatic feeder refill, and various alarms including rate tolerance and disturbance utilizing the PLC’s rack I/O.

Hardy’s HI 1756-FC 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.

The HI 1756-FC also includes Hardy’s core technologies of WAVERSAVER to eliminate the effects of surrounding vibration for fast, stable weight display, C2® electronic calibration without test weights, and INTEGRATED TECHNICIAN (IT) for system diagnostics and troubleshooting.
