Description
The Carrier HN61KL604 is a pilot relay that is used for Carrier HVAC equipment and is a pilot relay only for Carrier HVAC equipment. In other words, it is an electronic device that regulates the flow of high-power electricity in the system. It does this with a low-power signal from a control circuit. This type of relay is somewhat similar to a safety guard since it isolates the high-voltage circuits from the low-voltage control circuits. This separation assists in safeguarding some of the fine control subscriptions from the nasty effects of power surges or unstable voltage.
