Weigh module HI 1756-WS series

Hardy’s single (HI 1756-WS) and dual (HI-1756-2WS) are weigh scale modules that mount directly into an Allen-Bradley ControlLogix® PLC Chassis. They read weight and diagnostic data from one set or two separate sets of 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 and 2WS condition and digitize the weight signals and then transmit the selectable Gross, Net and/or Rate-of-Change data to the PLC processor. High data resolution allow the modules to tolerate large dead loads and over sizing of the load sensors while retaining a high level of usable resolution. The modules supply 5 volts of DC excitation to drive up to four 350 ohm load sensors or load cells associated with a single scale (four additional for the 2WS scale). They will support additional load cells with an external power supply.
