The Carlisle IntelliSpray Relay is a device that controls the flow of electric current in the IntelliSpray system, which is used for spraying foam insulation. The relay has a double-pole, double-throw (DPDT) contact configuration, which means it can switch between two circuits. The relay operates with a 24-volt direct current (VDC) coil, which is the part that activates the relay when energized. The Carlisle IntelliSpray Relay is designed to provide reliable and consistent performance in the IntelliSpray system.
