The heart of a KD Series digital countdown off delay or on delay timer is a digital integrated circuit. The timer function is to provide either an off delay or on delay to a load such as a relay. Timing can be set as either fixed or variable by an external resistor or potentiometer. Modules can be mounted to a circuit board as single or multiple units. With 1.75" leads, they can easily be wired to fit many applications requiring a miniature delay module. Available in standard and nonstandard voltages, the digital countdown timer series is versatile in time delay relay applications.
