KH Series Specification Applications Footprint Actions Part Numbers Products

The KH1 Analog Series on delay timer provides an on delay period between the application of input voltage and energizing a load. The timer is connected to a voltage source and a load. The on delay period begins when voltage is applied. The load remains deenergized until the end of the delay at which time it energizes. It remains energized as long as input voltage is present. When input voltage is removed, the load deenergizes and the timer is reset.

Typical application of the KH1 on delay timer is to configure a time delay relay by connecting the timer to a voltage source and a relay coil.
