The ATC Diversified TDC-120-AKA-300 is a delay-on-make (on-delay) timer for 120 V AC/DC, with isolated DPDT relay contacts rated 10 A resistive at 250 V AC or 24 V DC. Its delay is adjustable from 3 to 300 seconds with its onboard knob.
Upon application of supply voltage the delay begins; at the end of the delay the output relay energizes and stays energized until supply voltage is removed, which resets the timer.
Output: 2C DPDT relay, 10 A resistive at 250 V AC or 24 V DC; 211 VA inductive at 120 V AC. It has no LED indicator. Repeat accuracy: 1% maximum, no first cycle effect. Setting accuracy: Maximum setting ±10%, minimum setting +0%/-20%. Supply tolerance: ±10% of nominal; 50/60 Hz. Power: 3 W. Life: 10,000,000 operations mechanical, 100,000 electrical.
It plugs into an 8 pin octal socket (RB-08 or PF083A). It operates from 0 to +55 °C and stores from -45 to +85 °C. Approvals: UL Recognized (E55826).
