HI 1746-WS Weigh Scale Module

The HI 1746-WS Weigh Scale Module reads data from the company's load points (or industry-standard load cells) and puts the weight value into the SLC 500 processor. It also compares weight to set-point values (with pre-act values) and transfers the results to the SLC's input image table for quick response. There are two relay output drive signals that can be used for control directly from the module. Three LED status lights report functional characteristics.

The module provides five-V excitation voltage for up to four 350 ohm load sensors or eight New Standard 1000 ohm load sensors associated with a single vessel. Two setpoints can be established in the module with corresponding preact and deadband values, and two relay drive outputs are provided. The setpoint comparison status can be read in the input image table for quick response in addition to the relay drive signals. The module provides accurate weight readings with 20-bit A/D conversion, providing 985,000 counts of displayed resolution over the 0-30 mV range. Users can set the gross or net weight to zero at any point in the process. The module returns "weight-in-motion" and other status information.
