HARDY Instruments’ HI 1756-2WS, available in Australia from Scale Components , is a single slot dual channel weigh scale module that mounts in an Allen-Bradley ControlLogix chassis.
Just like the single-scale HI 1756-WS, the HI 1756-2WS reads weight and diagnostic data supplied by strain gauge load sensors or load cells from two different scales.
It communicates this data over the I/O chassis backplane to the ControlLogix processor.
The HI 1756-2WS module reduces installation costs, as it occupies only one slot of the 1756 I/O chassis and needs no external stand-alone scale instrument with a wired communications link to the PLC.
The weighing module includes Hardy Instruments' core technologies:
· Waversaver, eliminates the effects of vibration providing a stable weight display.
· C2, provides electronic calibration without the need for test weights.
· The Button, allows one touch calibration with C2 load sensors.
· Integrated Technician (IT) system, diagnostics and troubleshooting techniques.
