Time Delay Relays Dedicated - Delay-on-Make KRPS SERIES Description The KRPS Series is a factory programmed time delay relay available with 1 of 15 functions and measures only 2 inches square. The KRPS offers a wide range of fixed, onboard, or externally adjustable time delays. The output relay contacts offer a full 10A rating with complete isolation. Its microcontroller timing circuit provides excellent repeat accuracy and stability. Encapsulation protects against shock, vibration, and humidity. The KRPS Series is a cost effective approach for OEM applications that require small size, isolation, accuracy, and long life. Special time ranges and functions are available.

The Open Contact output relay is de-energized before and during the time delay. NC = Normally At the end of the time delay, the put energizes and remains Closed Contact energized until input voltage is removed. TD = Time Delay Reset: Removing input voltage resets the time delay and output. R = Reset = Undened Operation (Delay-on-Break) Time Input voltage must be applied before and during timing. Upon closure of the initiate switch, the output relay energizes. The DELAY-ON-BREAK (OFF-DELAY) V = Voltage time delay begins when the initiate switch is opened. The output S1 = Initiate Switch remains energized during timing. At the end of the time delay, NO = Normally the output de-energizes. The output will energize if the initiate Open Contact NC = Normally switch is closed when input voltage is applied. Closed Contact Reset: Re-closing the initiate switch during timing resets the time TD = Time Delay delay. Removing input voltage resets the time delay and output. t = Incomplete Operation (Recycling) Time Delay R = Reset Upon application of input voltage, the output relay energizes and = Undened the ON time begins. At the end of the ON time, the output de- V = Voltage RECYCLING (ON FIRST) Time energizes and the OFF time begins. At the end of the OFF time, NO = Normally the output energizes and the cycle repeats as long as input Open Contact voltage is applied. NC = Normally Closed Contact Reset: Removing input voltage resets the output and time TD1, TD2 = Time Delay delays, and returns the sequence to the first delay.
