The Littelfuse SSAC TDUS3000A is a solid-state single shot timer module for 24-120 V AC, with a 1 A solid-state output (10 A inrush). Its delay is adjustable from 1 to 1023 seconds in 1 s steps with DIP switches.
Input voltage must be applied before and during timing. A momentary or maintained closure of the initiate switch energizes the output for the set time; opening or reclosing the switch during timing has no effect.
Output: 1A SPST-NO. Off-state leakage about 5 mA and voltage drop about 2.5 V at full load. Repeat accuracy: ±0.5% or 20 ms, whichever is greater. Setting accuracy: ±2% or 20 ms, whichever is greater; ±5% over temperature and voltage. Reset time: 150 ms. Supply tolerance: ±20% of nominal; 50/60 Hz. Power: 2 VA.
It is surface mounted and has 0.250 in (6.3 mm) male quick-connect terminals. It operates from -40 to +60 °C and stores from -40 to +85 °C.
