KD Series Specification Applications Footprint Actions Part Numbers Products

The heart of a KD Series digital countdown off 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. The timing range can be either fixed or variable by means of an external resistor or potentiometer connected to the timer.

The 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 quite versatile for use in time delay relay applications.
