MECHANICAL SPECIFICATIONS
TDH-8080/8081
NOTES
[1] The accuracy specification applies for any combination of operating temperature and voltage.
For units with a timing range less than 1 second, add ±10 milliseconds to the ±10% tolerance.
[2] Transient and power loss specification 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-83726B.
[4] Terminals X1, X2, C1, D1 and D3 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 applied to the control terminal 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.)
[6] Time delays greater than 500 seconds are not MIL qualified.
A four digit number defines the adjustable time delay range in seconds (or milliseconds).
The first three digits are significant figures, used to define the upper limit of a DECADE RANGE.
The fourth digit represents the number of zeros to follow the first three digits.
SPECIFY
STANDARD DECADE RANGE
- 1001 = 0.1 to 1 second (100 to 1,000 milliseconds)
- 1002 = 1.0 to 10 seconds
- 5002 = 5 to 50 seconds
- 5003 = 50 to 500 seconds
An external resistor is used to obtain a specific time delay within the specified decade range.
The formula below provides the proper resistance value to achieve the desired time delay:
T1
Rext = (_____ - 1)
100,000 Ohms
Where:Rext = External resistance value (Ohms)
T0
T1
= Desired time in seconds
T0
= Minimum time (low end of the decade range) in seconds.
As an example, if using a 5 to 50 second adjustable timer and a 30 second delay is desired, the
calculation is:
30
Rext = (_____ - 1)
100,000 Ohms or Rext = 500 K Ohms
5
Recommended resistors IAW MIL-R-55182 1/8 Watt, 1% (RNC60HXXXXFS). External resistor not supplied.
[7] Quality level as specified in MIL-R-83726B, paragraph 3.1.1, 3.1.2 and 3.1.3.
