NOTES
1. The accuracy requirement applies to any combination of operating temperature and voltage. Add ±10ms for timing less than one second.
2. Recycle time to assure that the next timing cycle will be completed. Units can be recycled during timing and after time-out:
Delay on operate models – Power must be OFF the input at least 10 ms.
Delay on release models – Power must be ON the control terminal at least 10 ms.
3. Transient specifications are based on a maximum duty cycle of 1/50.
4. All wired terminals must be connected together during this test. Dielectric withstanding voltage and insulation resistance are measured between all mutually
insulated wired terminals and between all these terminals and case.

28C = Fixed, Delay on Operate (COTS version of M83726/28)
29C = Fixed, Delay on Release (COTS version of M83726/29)
30C = Adjustable, Delay on Operate (COTS version of M83726/30)
31C = Adjustable, Delay on Release (COTS version of M83726/31)
Time Delay Range (Within 0.1 to 500 seconds):
For /28 and /29 types (fixed types), the delay is expressed in
milliseconds in a four-digit code. The first three digits are significant.
The fourth is the number of zeros following the first three.
Example: 5002 is 50 seconds.
For /30 and /31 types (adjustable types), the delay decade range is
expressed in milliseconds in a four-digit code represesnting the upper
limit of the range. The first three digits are significant. The fourth is the
number of zeros following the first three.
Example: 1001 is 1 second, so the range is 0.1 to 1 second.
Terminals:
P= Socket Pin Terminals
S= Solder Hook Terminals
Note: Mil-spec models have “Y” type enclosure.
Time Delay Range (Within 0.1 to 600 seconds):
For fixed types, the delay is expressed in milliseconds in a four-
digit code. The first three digits are significant. The fourth is the
number of zeros following the first three.
Example: 5002 is 50 seconds.
For adjustable types, the delay decade range is expressed in
milliseconds in a four-digit code represesnting the upper limit of
the range. The first three digits are significant. The fourth is the
number of zeros following the first three.
Example: 1001 is 1 second, so the range is 0.1 to 1 second.
