* The accuracy specification applies to any combination of temperature and voltage.For
units with a timing range less than 1 second,add ±10 milliseconds to the ± 10% tolerance.
**Recycle time is that action which must occur to assure a new timing cycle can be completed within tolerance:
A. TD on operate--remove power from input teminals for the period specified.
B. TD on release--Apply power to the control terminal for the period specified.
C. "True"TD on release--Apply power to the input terminals for the period specified.

  †  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-83726A.
 ⇈ Definition of terminal type codes:
  PI=Plug-in type for use with mating relay socket.
  SH=Tinned solder hook terminals for direct hard wiring.
  PC=Tinned straight pins for printed circuit board insertion.
  TM=Compatible with M12883/52 socket module and M12883.53 mounting track. 		†††  Terminals x1 and x2 must be connected together during the test.Dielectric withstanding voltage and insulation resistance are measured between all mutually insulated terminals and between all terminals and case.   # Not available for new esign;commercially available.
