The Littelfuse SSAC TDSL110DLD is a digital single shot timer for 110 V DC, with isolated DPDT relay contacts rated 8 A resistive at 120/240 V AC. Its delay is adjustable from 0.1 to 102.3 seconds in 0.1 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 relay for the set time; opening or reclosing the switch during timing has no effect. For control panels and OEM equipment. DC units are reverse-polarity protected.
Output: 2C DPDT relay, 8 A resistive at 120/240 V AC; 1/3 hp at 120/240 V AC (isolated contacts). Indicator: LED: on when the output relay is energized. Repeat accuracy: ±0.1%. Setting accuracy: ±2%; ±5% over temperature and voltage. Reset time: 150 ms. Supply tolerance: -20% / +10% of nominal; 50/60 Hz. Power: 3.25 W max. Life: 10,000,000 operations mechanical, 1,000,000 electrical.
It plugs into an 11 pin Magnal socket (OT11-PC or RB11-PC (UL listing)). It operates from -20 to +65 °C and stores from -30 to +85 °C. Approvals: UL 508 (E57310), with socket.
