The Macromatic THR-15161-33J time delay relay uses a preset time amount to cycle between energized and de-energized states on a constant loop. For this unit, the time can be adjusted anywhere between 1-100 minutes using the blue dial on the housing. Once input voltage is introduced, the relay starts off in an energized state for the length of time that was set. Then it enters a de-energized state for the same duration. This cycle repeats itself continuously until the input voltage is removed.
