Models HI 1756-WS/ HI 1756-2WS - Weigh Scale Module Brochure

FEATURESTwo or three bi-color LEDs on the module’s front panel report functional characteristics. Being a true ControlLogix module the HI 1756-WS supports removal and insertion under power. 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.THE BUTTON®With one push of a button the weigh scalemodule automatically calibrates the C2 certified weighing system, making it ready for use. This saves system start-up time costs and aggravations.ApplicationsPROCESS WEIGHING• Batching/Blending• Filling/Dispensing• Level-by-Weight• Check WeighingFeaturesWAVERSAVER®• Ignores vibration on and around scalesC2® Electronic Calibration• Electronic calibration without test weightsINTEGRATED TECHNICIAN®• Weighing system monitoring and troubleshootingTHE BUTTON• One step calibration with C2 load cellsHardy’s HI 1756-WS is available as a single slot, single or dual scale, weigh scale module that mounts in an Allen-Bradley® ControlLogix® Chassis. It reads weight and diagnostic data from strain gauge load sensors or load cells and communicates this data over the I/O chassis Backplane to the ControlLogix Processor. The HI 1756-WS module reduces installation cost and increases speed since no external stand-alone scale instrument with a wired communications link to the PLC is needed.The HI 1756-WS conditions and digitizes the weight signal fifty times per second with over one million counts of resolution over a differential signal range of 0 to 15mV. It thentransmits the selectable Gross, Net and/or Rate-of-Change data to the processor. This high resolution allows the module to tolerate large dead loads and over sizing of the loadsensors 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(-WS), or eight load cells associated with a dual (-2WS) scale. It will support additional load cells with an external power supply.The HI 1756-WS supports the use of the producer/consumer technology in the ControlLogix system to transmit data. This type of communications is an intelligent data exchange in the system where the module produces data without having to be polled.HI 1756-2WS Dual Scalewww.hardysolutions.com • 800-821-5831HI 1756-WS Single ScaleWeigh Scale ModuleModels HI 1756-WS HI 1756-2WSAll information within is subject to change without notice.
