Single Channel ControlLogix PLC Plug-in Weigh Module

Hardy’s HI 1756-WS is a single slot, single scale, weigh scale module that mounts in an Allen-Bradley ControlLogix® local or remote 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 costs, 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 eight million counts of resolution over a differential signal range of -2.5 to 17.5mV. 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 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.
