HI 1769-2WS CompactLogix® Module

C2® Electronic Calibration Hardy Instruments' C2® core feature provides quick and easy electronic calibration of a weighing system without the need for heavy test weights. Read more about C2® Electronic Calibration INTEGRATED TECHNICIAN® Hardy Instruments Integrated Technician (IT) core feature helps you troubleshoot your weighing system and diagnose problems from the front of the instrument or via the PLC.  Read more about INTEGRATED TECHNICIAN® WAVERSAVER® Hardy Instruments' WAVERSAVER core technology eliminates the effects that surrounding vibration has on the scale weight signal, providing only true data for fast, accurate weight reading.

If you thought small size couldn’t mean high performance…

The HI 1769-2WS module reduces installation costs, as it needs no external stand-alone scale instrument with a wired communications link to the PLC. It also saves space, since two modules are integrated in one single scale package.

The HI 1769-2WS conditions and digitizes the weight signal fifty times per second with more than eight million counts of resolution over a differential signal range of 0 to 15mV. It then transmits the selectable Gross, Net, Tare and/or Diagnostics data from each of the two scales to the processor. This high resolution enables the module to tolerate large dead loads and over-sizing of the load sensors, while retaining a high level of usable resolution.

The module supplies 5 volts of DC excitation to drive up to four 350-ohm load sensors or load cells associated with each of two scales. It will support additional load cells with an external power supply.

Both HI 1769 Series Weigh Scale modules incorporates Hardy Instruments’ core features of WAVERSAVER®, C2® electronic calibration INTEGRATED TECHNICIAN™ (IT®). WAVERSAVER® eliminates the effects of unwanted plant and system vibration on the weigh system by permitting the weigh scale module to “see through” the unwanted vibration signals (as low as 0.25hz), while yielding a stable weight reading.

C2® is a field-proven means for calibrating the scale electronically without using test weights, saving the customer both time and money. IT, when used in conjunction with an IT junction box, provides built-in system diagnostics that enable you to troubleshoot and diagnose your weighing system.

Three bi-color LEDs on the HI 1769-2WS module’s front panel report its functional characteristics. At power-up the module checks for correct RAM, EPROM and EEPROM operation. A clear door and removable label enable positioning of your own unique information and viewing (once the door is closed).

Auto Zero Tracking allows the module to automatically compensate for small variations at the zero point of both scales. These variations may be caused by a slight material buildup on the scale platform or vessel. With Auto Zero tracking on, whenever the weight on the scale is within the adjustable zero tolerance (and the scale is not in motion) the gross weight will be set to zero.

A printed instruction manual, that is also available on the Hardy website, is supplied with the module.
