115Vac, 60 Hz. input types
CII 4600/4700 series interval
timers combine solid state
timing circuits with
electromechanical output
relays in robust hermetically
sealed enclosures. The 4600
types are fixed timers, while the
4700 models are adjustable via
an external resistor. Numerous
output options include 4A rated
contacts in 1, 2 and 4 form C
(SPDT, DPDT and 4PDT)
arrangements and 10A rated
contacts in 1-2 form C (SPDT-
DPDT) arrangements.

Apply power and the output will
energize. After time-out, the output will
revert to de-energized state. Remove and
reapply input to cycle.
Adjustable Timing Formula
(4700 types)
The resistance required to obtain timing
within this range is determined by using
the formula:
Rx = 400K (T/Tmax.) – 40K, where
Rx = External Resistance in Ohms,
T - Desired Time in Seconds, and
Tmax. = Maximum Time (Code).
A high quality deposited carbon ±1%,
0.1W (min.) resistor is recommended for
external resistance.
Part Numbering System
Typical Part Number
4722
–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 100ms and 600s for fixed (4600) timers, and
100ms and 240s for adjustable (4700) 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 4722–C–1102. This is a DC
unit in the -55°C to +125°C temperature range with a 2 form C (DPDT) contact
arrangement in a style “C” mounting, with a maximum time delay of 11s.
