Hardy Process - ControlLogix Weight Scale Module - HI1756-WS

Hardy’s single channel HI 1756-WS is a weigh scale modules that mounts directly into an Allen-Bradley ControlLogix PLC Chassis. It reads weight and diagnostic data from strain gauge load sensors or load cells and communicate this data over the I/O chassis backplane to the ControlLogix Processor.

• The HI 1756-WS conditions and digitizes the weight signal 110 times per second with over one million counts of resolution over a differential signal range of 0 to 15mV. It then transmits 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 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 (-WS), or eight load cells associated with a dual (-2WS) scale. It will support additional load cells with an external power supply.

• ADD-ON-PROFILES & FACEPLATE/AOI

• Hardy’s pre-programmed and pre-tested integration tools can reduce development time by 50 to 90%. Using a combination of Add-onProfiles

• (AOPs) and SE and ME HMI Faceplates with Add-on-Instructions, creates a synergistic method for EASY and seamless integration for weighing with Rockwell Automation PLCs/PACs using RSLogix® and Studio 5000®. 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.

• Two 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 CALIBRATION

• C2 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® 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® 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
