The Littelfuse SSAC TRDU120A3 is a digital multi-function timer for 120 V AC, with isolated DPDT relay contacts rated 10 A resistive at 120/240 V AC and 28 V DC. Its delay is adjustable from 0.1 seconds to 1705 hours with DIP switches.
21 timing functions selected with five switches on the face, ranges and multipliers set on DIP switches. One TRDU replaces up to three single-function timers.
Output: 2C DPDT relay, 10 A resistive at 120/240 V AC and 28 V DC; 1/3 hp at 120/240 V AC (isolated contacts), 21 functions, 11-pin dpdt. Indicator: Two LEDs: input voltage applied, output relay energized. Repeat accuracy: ±0.1% or 20 ms, whichever is greater. Setting accuracy: ±1% or 50 ms, whichever is greater; ±1% over temperature and voltage. Reset time: 50 ms. Supply tolerance: -20% / +10% of nominal; 50/60 Hz. Power: 3 W max. Life: 10,000,000 operations mechanical, 1,000,000 electrical.
It plugs into an 11 pin Magnal socket. It operates from -20 to +65 °C and stores from -40 to +85 °C.
