The ATC Diversified 425A-300-Q-10-M-D is a delay-on-make (on-delay) timer for 120 V AC, with isolated delayed relay contacts rated 5 A resistive. Its delay is adjustable from 0.01 s to 999 h.
Display: 3-digit green LED, timing down. Memory: EEPROM: keeps the elapsed time through a power loss. Setting: digital setting.
Output: SPDT instantaneous + SPDT delayed relay, 5 A resistive; 1/10 HP at 120 V AC. Indicator: Red timing LED: slow blink while timing, fast after time-out. Repeat accuracy: ±0.1%. Setting accuracy: 0.1% (crystal controlled). Reset time: 100 ms. Supply tolerance: +10% / -20%; 50/60 Hz. Power: 5 W max. Life: 10,000,000 operations mechanical.
It plugs into an 8 pin octal socket. Approvals: cULus, CSA, CE.
