Resideo DP2020A5022 2-Pole Relay 20A 24V

The Resideo DP2020A5022 is a compact (around 0.55 lbs) relay designed for various HVAC equipment. It acts like a switch that controls the flow of higher-voltage/current electricity for powering HVAC components based on control signals. Think of it as a middleman. The relay itself operates on a low voltage, typically 24V in this model, and uses that signal to open or close a circuit carrying higher voltage/current for powering components like motors or heating elements. This provides a safety benefit by keeping those higher voltages away from the control circuits. With a wide temperature tolerance (-4°F to 149°F) and compatibility with 60Hz electrical systems, the Resideo DP2020A5022 is suitable for various HVAC applications. By providing a safe and reliable way to control higher-power components, relays like the DP2020A5022 play an essential role in the operation of HVAC systems.
