Engineered for demanding industrial manufacturing environments, the HI 6850-SPWC delivers fast, stable, and accurate weight control with advanced features that streamline operations, reduce downtime and enhance productivity. With its built-in Setpoint Control application, the controller automates filling and dispensing processes in both Loss-in-Weight and Gain-in-Weight modes.

While in Loss-In-Weight mode, the setpoint controller will open relays (unlatch) when the weight reaches or falls below the setpoint threshold; while in Gain-In-Weight mode, the setpoint controller will close relays (latch) when the weight reaches or goes above the setpoint threshold. Coupled with a required 8-channel relay card, the controller can automatically control fillers, switches or valves that adjust tank or vessel setpoints on up to 4 channels.
“The HI6850-SPWC offloads specialized weighing application processing from the PLC, enabling both the PLC and the weight controller to each do what they do best,” said Tim Norman, Senior Product Manager at Hardy Process Solutions. ”The HI6850-SPWC can serve as a closed-loop weight-based Setpoint controller while serving up additional data to a PLC for optimizing overall manufacturing processes. It’s designed to meet the evolving needs of industrial manufacturers by delivering unmatched accuracy, configurability, and ease of use”
