Hardy HI 1756-WS ControlLogix® Weight Scale ModuleProduct Description
Hardy’s single (HI 1756-WS) is a weigh scale module that mounts 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.

Features
- Direct Back-plane Connectivity
- 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.
