HI 1756-FC

HI 1756-FC ControlLogix Weigh Feeder PLC Module

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 a slave 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.

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 1756-FC 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.

INTEGRATED TECHNICIAN® Operator Diagnostics
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.

FEED-MASTER
FEED-MASTER is a set of software controls designed to control volumetric and gravimetric feeders.
