The Littelfuse SSAC KRD9423A is a retriggerable single shot timer for 120 V AC, with isolated SPDT relay contacts rated 10 A resistive at 125 V AC. Its delay is adjustable from 0.1 to 10 minutes with its onboard knob.
Input voltage must be applied before and during timing. Closing the initiate switch energizes the output and starts the delay; at the end of it the output de-energizes. Reclosing the switch resets the delay and restarts timing with the output still energized (retriggerable).
Output: 1C SPDT relay, 10 A resistive at 125 V AC; 5 A resistive at 230 V AC and 28 V DC; 1/4 hp at 125 V AC (at 40 °C), output initially de-energized. Repeat accuracy: ±0.5% or 20 ms, whichever is greater. Setting accuracy: Factory calibration ±5%; ±5% over temperature and voltage. Reset time: 150 ms. Supply tolerance: -20% / +10% of nominal; 50/60 Hz. Power: 2 VA. Life: 10,000,000 operations mechanical, 100,000 electrical.
It is surface mounted and has 0.250 in (6.3 mm) male quick-connect terminals. It operates from -20 to +60 °C and stores from -40 to +85 °C.
