Part Numbering System
Typical Part Number
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.

Model Number:
2401 = Fixed timer, -55°C to +85°C
2402 = Fixed timer, -55°C to +125°C
Electrical Specifications
Timing Range: 50 ms to 600 s.
Tolerance: 10ꢀ or 10 ms, whichever
is greater.
Header Style (see Header Options drawings):
1 = Hook terminals 2 = Straight terminals, short
3 = Straight terminals, long
Recycle Time: 10 ms.
Recovery Time: 20 ms.
Input Data:
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.
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;
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.
