The Littelfuse SSAC PRLS1110 is a single shot timer for 12 V DC, with isolated SPDT relay contacts rated 10 A resistive at 28 V DC and 240 V AC. Its delay is fixed at 10 seconds, set at the factory.
Input voltage must be applied at all times. A momentary or maintained closure of the initiate switch transfers the output contacts and starts the delay, and the LED flashes; at the end of the delay the contacts return. Reclosing the switch during timing has no effect. For non-critical timing at low cost. DC units are reverse-polarity protected.
Output: 1C SPDT relay, 10 A resistive at 28 V DC and 240 V AC; 1/3 hp at 120/240 V AC (isolated contacts). Indicator: LED: flashing while the output is energized and timing. Repeat accuracy: ±2%. Setting accuracy: Factory calibration ±10%; ±10% over temperature and voltage. Reset time: 50 ms. Supply tolerance: -15% / +20% of nominal. Power: 2.25 W. Life: 10,000,000 operations mechanical, 1,000,000 electrical.
It is socket mounted, with octal 8-pin plug-in terminals. It operates from -20 to +65 °C and stores from -30 to +85 °C.
