Off Delay Timer

Specification Applications Footprint Actions Part Numbers Products

The KH2 Series off delay timer operates with power continuously applied. The load, such as a relay coil, is energized when an external control voltage is applied. When the control voltage is removed, the off delay period begins while the load remains energized. At the end of the delay, the load deenergizes and the timer resets.

This analog delay timer module is available with either fixed or adustable timing ranges. An external potentiometer can be connected to the timer for variable off delay. A resistor can be used to configure a fixed timer. Both on delay and off delay timer modules may be pcb mounted for multiple delay actions. Voltage input available from 12 to 110 Volt DC and 12 to 240 Volt AC.
