TIME DELAY ON OPERATE
NOTES
[1] The accuracy specification applies for any combination of operating temperature and voltage.
[2] The accuracy will not be affected by power interruptions up to 1 millisecond, spaced at
least 10 milliseconds apart. Transient and power loss specifications are based on a maximum
duty cycle of 1/50.
[3] EMI test limits will not be exceeded during the timing interval or when continuously
energized under steady state conditions, per paragraph 3.23, MIL-R-83726C.
[4] Terminals X1, X2, A1, B1 and A3 must be connected together during the test. Dielectric
withstanding voltage and insulation resistance are measured at sea level between all
mutually insulated terminals and between all terminals and case.
[5] Recycle time is defined as the minimum time power must be removed from terminal X1 to assure
that a new cycle can be completed within the specified timing tolerance.
[6] A four digit number defines the time delay in milliseconds. The first three
digits are significant figures, used to define the specific time delay. The fourth digit
represents the number of zeros to follow the first three digits.
Examples:
1001 = 1 second (1,000 milliseconds)
2502 = 25 seconds (25,000 milliseconds)
5000 = 0.5 seconds (500 milliseconds)
[7] Quality level as specified in MIL-R-83726, paragraph 3.1.1, 3.1.2 and 3.1.3.

Application notes
DERATING OF CONTACTS FOR DC VOLTAGES
ABOVE NOMINAL RATING
N°101
To establish a standard for the derating of relay contacts is, at best, a subjective practice. Limitations are governed by the
type of relay, contact gap, maximum voltage capabilities of the relay contact system, and the contact material.
The most common method is to derate the contacts by use of the Power Formula, using the known current and voltage.
This method is valid only for
Resistive Loads,
and is an approximation only; keeping in mind the limitations mentioned
above.
Power = IE (Current x Voltage)

A designer is working with a 55 volt DC system and has a relay rated at 10 amps resistive at 28 volts DC.
What is the maximum current that can be switched at 55 Vdc.

In addition, the user should always be concerned about the following:
1. Derating contacts that are rated for less than 10 Amperes at nominal voltage.
2. Derating contacts for use in system voltages above 130 Volts DC
