MECHANICAL SPECIFICATIONS TDH-7060/7061

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-PRF-83726B.
[4] Terminals X1, X2, R1, R2 and L 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 maximum 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 seconds (or 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.
                            SPECIFY    STANDARD DECADE RANGE
                           - 1001   =  0.1 to 1 second  (100 to 1000 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

    Recommended resistors IAW MIL-R-55182 1/8 Watt, 1% (RNC60HXXXXFS).
    External resistor not supplied.
