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.

Fixed Timing, Relay Output

Electrical Specifications

Timing Range: 50 ms to 600 s.

Tolerance: ±10% or 10 ms, whichever

is greater.

Recycle Time: 10 ms.

Recovery Time: 20 ms.

Input Data:

Input Voltage: 18 to 31Vdc.

Current Drain: 85mA @ 31Vdc, 25°C.

Output Data:

Output Form: 2 Form C (DPDT).

Output Rating:

2A resistive at 30Vdc;

125mA resistive at 115Vac, 400 Hz.

Transient Protection: 80Vdc for

50ms.

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.
