HI 1756-FC ControlLogix PLC Weigh Feeder
Used in new applications or to retrofit volumetric feeders, the HI 1756-FC feeder control module mounts directly into your 
ControlLogix® chassis and controls many standard feeding devices as well as your proprietary designs.
Worry Free Operation
The HI 1756-FC feeder control module will watch your process and notify you of problems. Prompts on your system’s HMI display and PLC alarm relay outputs occur with tolerance errors and other failures.
Multiple Feeder Control
The HI 1756-FC is a powerful building block when it comes to multiple feeder
systems. It can be secondary to other process inputs through the ControlLogix® processor.
Automatic Rate and Weight Calibration
A five-point auto rate calibration automatically allows the module to calibrate itself to the characteristics of the feeder and the material being fed. This allows for a higher feed accuracy over a broader range of feed rates.
