MIL-R-83726/22F
REQUIREMENTS: Operating data:
Timing action: Repeat cycle.
Cycle rate: 10 maximum per second; 1.0 minimum per 60 seconds; on time 50 percent. Timing accuracy: 1/ 10 percent of the total cycle time.
Recycle time: 2/ 10 milliseconds. Input data:
Input voltage: 28 V dc nominal; range 18 to 32 V dc. Duty rating: Continuous.
Current drain: 5 milliamperes maximum plus load at 25°C.
Polarity protection: The timer shall be inoperative during, and unclamped by, reversal of the polarity of the operating voltage.
Output data:
Configuration: SPST; switch closure to +28 V dc.
Rating: Equivalent of two MS25237-387 lamps in parallel. Suppression: Inductive suppression provided for output protection. Voltage drop: 2 V dc maximum.
Endurance: 1,000,000 cycles minimum for test.
Qualification: 2,000 hours or 1,000,000 cycles, whichever is less.
1/ The accuracy requirement applies for any combination of operating temperature and voltage.
2/ Recycle time is defined as the maximum 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.)
