CII 1600/1700 series delay on operate timers combine solid state timing circuits with electromechanical output relays in robust hermetically sealed enclosures. The 1600 types are fixed timers, while the 1700 models are adjustable via an external resistor. Numerous output options include 4A rated contacts in 1-4 form C (SPDT 4PDT) arrangements and 10A rated contacts in 1-2 form C (SPDT-DPDT) arrangements.

A high quality deposited carbon 1%, 0.1W (min.) resistor is recommended for external resistance. Input Voltage DC DC Temperature Range -55C to +85C -55C to +85C Part Numbering System Typical Part Number 1722 -C - 1102 Model Number: Four digit code from table above. Mounting (see outline dimension drawings): A = Studs on bottom B = Studs on top C = Studs on side Timing Code: Four-digit code for any value between 50ms and 600s for fixed (1600) timers, and 50ms and 240s for adjustable (1700) timers. 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. Adjustable timers cover one decade, e.g., 62 ms to 620 ms. The upper decade limit is Tmax. in the timing formula and is the the value defined by the timing code in the part number. A typical part number for an adjustable timer would be 1722-C-1102. This is a DC unit in the -55C to +125C temperature range with a 2 form C (DPDT) contact arrangement in a style "C" mounting, with a maximum time delay of 11s.
