Relays

    Building automation relays are integral components in building automation systems that enable control and switching of electrical circuits. These relays function as electromechanical switches that use an electromagnetic coil to open or close contacts, allowing or interrupting the flow of electricity. Building automation relays come in various types and configurations to suit different applications. They can be categorized into dry contact relays, latching relays, optoisolated relays, pilot relays, polarized relays, power relays, and specialty peripheral controls. These relays play a crucial role in controlling lighting systems, HVAC equipment, motorized devices, and other electrical loads within a building automation infrastructure. They enable efficient energy management, system integration, and automation by providing reliable and precise control over various building automation functions.
