Overview
HI 1756-WS and 1756-2WS
Single and Dual ControlLogix® Weigh Scale Modules
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.
The HI 1756-WS and 2WS both support 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.
Hardy’s process weighing solutions are easy-to-install, configure, commission and operate. They are easy-to-maintain and save you time, money, raw materials and/or finished product. Visit our Case Studies or Application Notes to learn more.
