HI 1746-WS Datasheet

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 weighingsystem, 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 cellsThe HI 1746-WS Weigh Scale Module is specifically designed to work with an Allen-Bradley® SLC™ 500 Series processor. Thisweighing instrument installs like an I/O module in either a local or remote rack.The HI 1746-WS Weigh Scale Module reads net, gross and rate-of-change data from Hardyload points (or industry standard load cells) and sends this data to the SLC 500 processor. It also compares weight to set-point values (with pre-act values) and transfers the results to the SLC's input image table for quick response. Two relay output drive signals can be used for control directly from the module. Three LED status lights report functional characteristics.FEATURESThe HI 1746-WS provides 5V excitation voltage for up to four 360-Ohm load sensors associated with a single vessel and will support up to eight load sensors with external power. Two setpoints can be established in the module with corresponding pre-act and deadband values, and two relay drive outputs are provided. The setpoint comparison status can be read in the input image table for quick response in addition to the relay drive signals. The module provides accurate weight readings with 20-bit A/D conversion, providing 985,000 counts of displayed resolution over the 0-15mV range. You set the gross or net weight to zero at any point in the process. The module returns "weight-in-motion" and other status information.www.hardysolutions.com • 800-821-5831Weigh Scale ModuleModel HI 1746-WS Hardy Bench Scales, Floor Scales and Load PointsHardy C2 Certified CableHardy Junction Box (HI 215IT Series) with INTEGRATED TECHNICIANTYPICAL CONFIGURATIONADVANTAGE® Series Load Point with C2 CalibrationANY-WEIGH®ScalesTo learn more aboutthe HI 1746-WS 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 1746-RTA configuration, the weigh scale modules can be replaced without disturbing the wiring.• Cable (-C6)Hardy provides an optional 6-foot (1.8m) 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.
