The Littelfuse SSAC HSPZA22SL is a solid-state single shot / lockout timer module for 24-240 V AC, with a 1 A solid-state output (10 A inrush). Its delay is adjustable from 1 second to 1023 hours with DIP switches.
Single shot / lockout: with input voltage applied, a momentary or maintained closure of the initiate switch energizes the output for the single-shot delay (TD1); the lockout delay (TD2) then follows, and the switch has no effect until it ends. Removing input voltage resets both delays.
Output: 1A SPST-NO. Off-state leakage about 5 mA and voltage drop about 2.5 V at full load. Repeat accuracy: ±0.1% or 20 ms, whichever is greater. Setting accuracy: ±1% or 20 ms, whichever is greater; ±2% over temperature and voltage. Reset time: 150 ms. Supply tolerance: ±15% 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.
