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.

4600/4700 Series Interval Timers

Fixed/Adjustable Timing, Relay Output

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.

Electrical Specifications

Timing Range:

4600 series (fixed): 100 ms to 600 s.

4700 series (adjustable): 100 ms to

240 s.

Tolerance: ±10%

Recycle Time: 10 ms (DC input),

50ms (AC input).

Operate Time (Max.) : 10 ms (4A

models), 20ms (10A models).

Input Voltage: 18 to 31Vdc,

105 to 125Vac, 400 Hz.

Current Drain (at 25°C, 28Vdc):

DC Coil, 10A contacts:

1- and 2-pole: 135mA maximum.

AC or DC Coil, 4A contacts:

1-pole: 100mA maximum.

2-pole: 150mA maximum.

3- and 4-pole: 200mA maximum.

Contact Ratings:

DC Coil, 10A contacts:

10A resistive @ 30Vdc.

5A inductive @ 30Vdc.

5A resistive @ 115 Vrms, 400 Hz

3A inductive @ 115 Vrms, 400 Hz

AC or DC Coil, 4A contacts:

4A resistive @ 30Vdc.

1A inductive @ 30Vdc.

2A resistive @ 115 Vrms, 400 Hz

1A inductive @ 115 Vrms, 400 Hz

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.

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.

Timing Diagram

Apply power and the output will

energize. After time-out, the output will

revert to de-energized state. Remove and

reapply input to cycle.
