More Information

Overview Manuals Weight Processing Calibration Tools SLC Integration Product Applications

Features:

  • Direct SLC integration: Delivers weight data through the controller backplane.
  • Vibration rejection: WAVERSAVER stabilizes readings around operating machinery.
  • Electronic calibration: C2 and THE BUTTON reduce dependence on test weights.
HI 1746-WS turns an SLC 500 rack position into a complete industrial weighing interface.

The module reads Hardy load points or compatible load cells, compares weight against setpoints and transfers results directly to the SLC input image.

Diagnostics and electronic calibration reduce commissioning time while keeping scale control inside the existing PLC program.

For HI 1746-WS sourcing, Apter Power can help confirm SLC processor, module series, firmware, slot mapping, load-cell interface and calibration records. HARDY HI 1746-WS is listed as SLC 500 Weigh Scale Module.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Measurements: Reports net, gross and rate-of-change data.
  • Conversion: Uses a 20-bit A/D converter with 20 updates per second.
  • Setpoints: Compares weight to setpoint and pre-act values.
  • Fast control: Two TTL drive signals support direct output action.
  • C2 calibration: Supports electronic calibration with compatible load points.
  • Test weights: Conventional test-weight calibration remains available.
  • WAVERSAVER: Rejects low-frequency vibration from nearby machinery.
  • INTEGRATED TECHNICIAN: Supports weighing-system monitoring and troubleshooting.
  • Processor family: Works with SLC 5/02 through SLC 5/05 processors.
  • Rack use: Fits one slot in local or remote I/O.
  • Data access: Uses 32 scanned I/O words and 128 M-file words.
  • Series control: Series A needs firmware 2.0 or later for direct M-file mapping.
  • Batching systems: Measures ingredients and triggers pre-act control near target weight.
  • Filling machines: Sends fast setpoint results to the PLC sequence.
  • Check weighing: Compares product weight with acceptance limits.
  • Material handling: Integrates hopper, vessel and conveyor scales with SLC logic.
Description
HI 1746-WS installs as an I/O module in a local or remote SLC 500 rack and converts load-cell signals into net, gross and rate-of-change data for the processor. Integrated setpoint comparison and two TTL output-drive signals let a weighing application react quickly without a separate stand-alone weight controller.

HI 1746-WS combines WAVERSAVER vibration rejection, C2 electronic calibration and INTEGRATED TECHNICIAN diagnostics. These functions shorten setup and fault finding in batching, filling and check-weighing systems while preserving direct access to weight and status data through the SLC backplane.
Technical notes
Before replacing HI 1746-WS, record the SLC slot, Series A/B/C identity, firmware, M-file mapping, scale wiring and calibration reference. Series A requires firmware 2.0 or later for direct M-file access. Preserve load-cell excitation and shield connections; an incorrect mapping or calibration restore can produce believable but wrong weight values.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What does HI 1746-WS add to an SLC 500 system?
HI 1746-WS adds direct load-cell measurement, net/gross/rate-of-change data, setpoint comparison and weighing diagnostics in one SLC rack slot.
Which SLC processors can use HI 1746-WS?
It is designed for SLC 5/02, 5/03, 5/04 and 5/05 processors in local or supported remote I/O arrangements.
How does HI 1746-WS reduce vibration error?
WAVERSAVER filters low-frequency vibration around the scale so the controller receives a more stable weight value.
Can HI 1746-WS be calibrated without test weights?
Yes. C2 electronic calibration is available with compatible Hardy load points; conventional test-weight calibration is also supported.
What should be preserved before replacing HI 1746-WS?
Record the slot, module series, firmware, I/O and M-file mapping, setpoints, load-cell wiring, shield connection and current calibration reference.
Why can a HI 1746-WS replacement show a plausible but wrong weight?
Incorrect scale wiring, mapping, excitation, parameter restore or calibration data can produce a stable value that is not accurate; verify with a known load.
