Littelfuse KSD1420, KSD1 Series, 120VAC, On-Delay Time Delay Relay SPST-NO (1 Form A) 0.1 Sec ~ 10 Sec Delay Chassis Mount

The KSD1 Series features two-terminal, series-connection with the load. The KSD1 Series is an ideal choice for delay-onmake timing applications. This series is designed for general purpose commercial and industrial applications where a small, cost effective, reliable solid-state timer is required. The factory calibration for fixed time delays is within 5% of the target time delay. The repeat accuracy, under stable conditions, is 0.5% of the selected time delay. This series is designed for popular AC and DC voltages. Time delays of 0.1 seconds to 1000 minutes are available in 6 ranges. The output is rated 1A steady and 10A inrush. The modules are totally solid state and encapsulated to protect the electronic circuitry.

Operation (Delay-on-Make)

Upon application of input voltage, the time delay begins. The output is de-energized before and during the time delay. At the end of the time delay, the output energizes and remains energized until input voltage is removed.

Reset: Removing input voltage resets the time delay and output.
