|  MIL-R-83726/24L
REQUIREMENTS:
Operating data:
Timing action: Delay-on operate.
Time delay: Fixed; select from .05 to 500 seconds.
Timing accuracy: 10 percent of the nominal value. 1/
Recycle time: 10 milliseconds. 2/
Power interrupt: The accuracy will not be affected by power interruptions up to 1 millisecond
spaced at least 10 milliseconds apart.
Input data:
Input voltage: 28 V dc nominal; range 20 V dc to 32 V dc.
Duty rating: Continuous.
Current drain: 10 milliamperes maximum plus load at +25C.
Polarity protection: The timer shall be inoperative during, and undamaged by, reversal of
the polarity of the operating voltage.
Output data:
Configuration: SPST; switch closure to +28 V dc.
Rating: 150 milliamperes maximum.
Suppression: Inductive suppression provided for output protection.
Voltage drop: 2 V dc maximum.
Leakage current: 1.0 microampere maximum at 28 V dc and +25C; 10 microamperes maximum
at 28 V dc and +125C.
Endurance (life): 1,000,000 cycles minimum for test.
Qualification: 2,000 hours.
Electrical data:
Transients: In accordance with MIL-STD-704 for 28 volts dc system (figure 11).
1/ The accuracy requirement applies to any combination of operating temperature and voltage.
2/ Recycle time is defined as the minimum time that power must be removed from the input terminals
to assure that the next timing cycle will be completed within the specified timing tolerance. (Units
can be recycled during timing or after time-out.)
