MIL-PRF-83726/31J
REQUIREMENTS:
OPERATING REQUIREMENTS:
Timing action: Delay-on-release.
Time delay: Adjustable; select from 0.1 second to 500 seconds.
Timing accuracy: ±10 percent of nominal value. (The accuracy requirement applies for any combination of
operating temperature and voltage. External resistors shall be in accordance with
MIL-R-10509, characteristic C or equivalent. Add ±10 ms for timing less than 1 second.)
Recycle time: 50 milliseconds maximum. (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.))
Power interrupt: 500 microseconds. (Transient and power loss specifications are based on a maximum duty
cycle of 1/50.)
Extraneous voltage: 7 V dc minimum.
Control voltage: 20 V dc to 30 V dc.
Control current: 15 milliamperes maximum at 25C.
Operating current: 150 mA maximum at 25C.
INPUT REQUIREMENTS:
Input voltage range: 20 V dc to 30 V dc. (EMI test limits will not be exceeded during the timing interval or when
continuously energized under steady-state conditions in accordance with the EMI test of MIL-PRF-83726.)
Duty rating: Continuous.
Current drain: (quiescent): 5 milliamperes maximum at 25C.
Polarity protection: The timer shall be inoperative during, and undamaged by, reversal of the polarity of the
operating voltage or control voltage.
OUTPUT REQUIREMENTS:
Configuration: DPDT.
Life: See table I.
