Product Overview
This time delay relay, part number 16D74 and 105241-01 from Allied Air Enterprises (often cross-referenced as Lennox 16D74), is an essential electrical control device for HVAC systems. It provides both a fixed 1-second delay-on-make and a fixed 45-second delay-on-break function, crucial for optimizing fan control and sequencing in air handlers and furnaces. Operating at 24 VAC and 50/60 Hz, this solid-state, encapsulated unit is designed for reliable performance in heating and cooling applications, helping to prevent pressure surges and protect evaporator coils from freezing. It replaces part number 19W66 and features approximate dimensions of 1.21 inches deep by 2 inches high by 2 inches wide. The unit weighs approximately 0.2 to 0.75 pounds.
