Description
Hartland Controls 90370 Relay is an electromechanical switching component intended for low-voltage control applications in HVAC systems. Operating with a 24-volt coil, and single-pole double-throw contact configuration, the relay direct electrical signal between alternate circuit paths during heating, cooling and ventilation sequences. It is frequently used into furnaces air handlers condensers, and automation panels where controlled switching, and circuit isolation are necessary for dependable equipment coordination. Within the electrical control arrangement the relay contributes to signal routing, load management, and stable operational sequencing throughout ongoing operationality.
