Feeder controller
HI 1769-FC Hardy Process Solutions

Easy to install, simple to set-up: Hardy's Weigh Feeder Control Module mounts directly into your Allen-Bradley® MicroLogix™ 1500 or CompactLogix™ chassis and supports ADD ON PROFILE set-up, making installation and programming a "SNAP and a CLICK".

The HI 1769-FC Feeder Control module is a self-contained, microprocessor-based CompactLogix™ and MicroLogix™ 1500 I/O solution that automatically calculates and adjusts tuning parameters typically required to maintain desired flow rates in a dispensing or filling system. It is used in a variety of material-flow applications, such as auger, belt, and vibration-based feeders.It can be operated in batch, automatic, or manual mode.

Algorithms contained in the HI 1769-FC compare user defined flow rates to the actual flow rates by continuously monitoring changes in the system weight over short intervals of time; the 1769-FC then calculates the adjustments necessary to achieve the user defined rate and instructs the PLC to adjust the speed of the feeding or dispensing device.

The 1769-FC updates 100 times per second and is capable of 8,388,608 counts of resolution, enabling the instrument to precisely determine target flow rates and tolerate large "dead" loads in a weigh system.
