Time Delay in a Small Package

The ICS KM Series Fixed-Time Delay Microtimer is designed to provide standard time delay actions, operate on commonly availabe voltages and to fit where space is limited. A generous selection of standard and custom time ranges and voltage options make this timer quite versatile. With output current capability up to 200mA, it is suitable for controlling many of today's readily available relays.
KM Series Microtimer includes off delay and on delay
