KD Series Action 5 & 6 Icsotimers

Repeat Cycle Timer

The ICS KD series repeat cycle timer produces an output which alternates between energized and deenergized states at a repetitive rate. The first cycle begins when input voltage is applied to the timer. During this period the output is deenergized. At the end of this off time, the output energizes and the on time begins. When the on time ends, the output deenergizes and the off time repeats. This off/on sequence repeats continuously while input voltage is present. When input voltage is removed, the output deenergizes and the timer resets.
The KD5 Series repeat cycle timer provides equal off and on times, controlled by a single timing resistor or potentiometer. The KD6 Series produces two independent on and off times, controlled by two separate resistors or potentiometers.
