A Percentage Timer is a time delay relay commonly used in applications such as irrigation, chemical feeding, electric heating & cooling, motors and lubrication systems. The Percentage Timer provides an output that cycles ON & OFF continuously. The duty cycle of the ON time is adjustable in percent of the total cycle time. Total cycle times in seconds, minutes and hours are available. For example, a Percentage Timer with total cycle time of 1 minute, set to 10%, provides a 6 second ON TIME followed by a 54 second OFF TIME. This cycle will keep repeating so long as voltage is applied to the Percentage Timer.
