NOTES
MECHANICAL SPECIFICATIONS
[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
[3] EMI test limits will not be exceeded during the timing interval or when continuously
[4] Terminals X1, X2, R1, R2 and L must be connected together during the test. Dielectric
[5] Recycle time is defined as the maximum time power must be removed from terminal X1 to assure
[6] A four digit number defines the time delay in seconds (or milliseconds). The first three
calculation is:
[7] Quality level as specified in MIL-R-83726B, paragraph 3.1.1, 3.1.2 and 3.1.3.

withstanding voltage and insulation resistance are measured at sea level between all mutually
insulated terminals and between all terminals and case.
that a new cycle can be completed within the specified timing tolerance.
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.
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:
