B Controls DH-7805 Liquid Level Control Relay

The B Controls DH-7805 Liquid Level Control Relay is a DH-series industrial relay designed to automate pump and valve actuation based on liquid level. The product data lists 440–480 V as the primary voltage and 220 V as the secondary, indicating it is built to interface with high-voltage mains equipment while providing a lower-voltage control signal. As part of the DH family, the DH-7805 is intended for use in tanks, sumps, and process vessels where maintaining level within a set range is required, typically by energizing a pump or switching a valve when the level reaches the designated point. The compact DH-7805 form-factor fits standard control panel configurations and relies on the DH-series construction to support reliable switching of load equipment in industrial environments. This model is suited for applications where a robust level-control relay is needed to automate routine operations, reduce manual intervention, and improve process consistency in liquid handling systems.
