CII 2400 series delay on operate timers combine solid state timing circuits with relay outputs in robust hermetically sealed enclosures. They are fixed timers. The 2 Form C (DPDT) output relay is rated 2A. Timing Diagram INPUT ON OFF OUTPUT ON OFF < DELAY > Part Numbering System Typical Part Number 2401 –1 A – 1102 Model Number: 2401 = Fixed timer, -55°C to +85°C 2402 = Fixed timer, -55°C to +125°C Header Style (see Header Options drawings): 1 = Hook terminals 2 = Straight terminals, short 3 = Straight terminals, long Mounting (see outline dimension drawings): A = Plain case B = Bracket B C = Studs on side E = Bracket E Timing Code: Four-digit code for any value between 50ms and 600s. The timing code consists of four digits and gives the time in ms. The first three digits are the significant figures and the last digit is the number of zeros following the significant figures; thus 50 ms would be coded 0500, 1.1 s would read 1101, and 1 m (60 s) would be 6002. A typical part number would be 2401–1A–1102. This fixed timer operates at -55°C to +85°C, has hook terminals, style “A” mounting, and a time delay of 11s.
