HI 1769-WS and 2WS Datasheet

FEATURESTwo or three bi-color LEDs on the module’s front panel report functional characteristics. A clear door and removable label enable positioning of your own unique information and viewing once the door is closed. C2® ELECTRONIC CALIBRATIONC2 enables electronic calibration of the weigh system without test weights. This saves system start-up costs and aggravation. Of course, even if C2 certified load sensors are not used, the system can still be calibrated the slow, traditional way using certified test weights.WAVERSAVER®WAVERSAVER eliminates the effects of unwanted plant vibration on or around the scale by permitting the weigh module to “see” through the unwanted vibration signals - as low as 0.25Hz - while yielding a stable actual reading.INTEGRATED TECHNICIAN®INTEGRATED TECHNICIAN, used in conjunction with an IT Junction Box, provides built-in system diagnostics that enable you to troubleshoot and diagnose your weighing system. You can read individual load sensor voltages and weights, make comparisons, and isolate individual system components for quick and easy troubleshooting.ApplicationsPROCESS WEIGHING• Batching/Blending• Filling/Dispensing• Level-by-Weight• Check WeighingFeaturesDirect Backplane to the CompactLogix™ and MicroLogix™ 1500 PLC:• Reduce installation time and system costs with no need for external wiringWAVERSAVER®• Ignores vibration on and around scalesC2® Electronic Calibration• Electronic calibration without test weightsINTEGRATED TECHNICIAN®• Weighing system monitoring and troubleshootingHardy’s compact weigh scale module is available in single channel or dual channel models for use with the Allen-Bradley® MicroLogix™ 1500 and CompactLogix® controllers. The HI 1769-2WS and HI 1769-WS read and condition weight and diagnostic data from strain gauge load sensors or load cells and communicate this data over the I/O chassis backplane to the MicroLogix1500 or CompactLogix processor. Both modules reduce installation costs, as they do not require an external stand-alone scale instrument with a wired communications link to the PLC. The HI 1769-WS conditions and digitizes the weight signal fifty times per second with over eight million counts of resolution over a differential signal range of 0 to 15mV. It then transmits the selectable Gross, Net, Rate-of-change and/or Diagnostics data to the processor. This high resolution enables the module to tolerate large dead loads and oversizing 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 a single scale (-WS), or eight load cells associated with a dula (-2WS) scale. It will support additional load cells with an external power supply.www.hardysolutions.com • 800-821-5831Weigh Scale ModuleModels HI 1769-WS HI 1769-2WSTYPICAL CONFIGURATIONTo learn more aboutthe HI 1769-WS / HI 1769-2WS ,visit our web site for:• full product specifications• ordering information• application notes• technical description• operator’s manualwww.hardysolutions.comor call us: 800-821-5831+1-858-278-2900www.hardysolutions.com • 800.821.5831OPTIONS• Remote Termination Assembly (-RTA)The weigh scale module optional Remote Termination Assembly provides connection points between the cable assembly to the module and individual wires from the junction box, or load sensors, of up to two scales. The RTA is designed for standard DIN mounting rails or standoffs. With an HI 1769-RTA configuration, the weigh scale modules can be replaced without disturbing the wiring.• Cable (-C6 -DC6)Hardy provides an optional 6-foot cable assembly from the weigh scale module to the remote termination assembly for both single and dual configuration.• Options OrderingOptions can be ordered at the same time the module is ordered by adding the dash designators to the end of the module number.
