Material Feed Management by Weight for ControlLogix® PLCs

The HI 1756-nDF ControlLogix Dispenser/Filler module is the easy answer to a variety of material feed applications, especially, when speed and accuracy of the feed are paramount to the process. The module batches, fills, or dispenses aggregates, granulates, liquids, or gases, handling the entire feed process.

The internal set point control is moved closer to the process, by taking it out of the PLC and into the module. This eliminates timing issues created by non-deterministic messaging. To compensate for flow rate variations during the feed, real-time target (preact) adjustments can be sent from the PLC, or be calculated by the module. Modules come in single or dual-scale configurations. Each scale is fitted with a choice of two integrated solid state DC or AC relays to control fast and slow feed rates.

The HI 1756-nDF will calculate and transmit gross weight, net weight & flow rate outputs simultaneously. Non-linear flows due to varying densities and head pressures are a thing of the past with its predictive algorithm automatically adjusting the system’s setpoint preact function.

These modules can be inserted and removed under power without disruption of any other modules in the system (racks). This makes it possible to replace a failed module while keeping the rest of the system running. Status indicators are provided on the front of the module for fault status. A status block will provide information to the processor for alarming and troubleshooting.

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-nDF 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.
