Motor Controls: Time Delay Relays

Motor Controls: Time Delay Relays is part three of the Motor Controls eight-part training series.

The course introduces time delay relays. An integral part of an industrial control system, they are used to provide time delays which permit the operations of a machine to occur in the proper sequence and order. Timers are often used to control the starting sequence of large motors that must be step-started or to control the starting of several motors which cannot be permitted to start simultaneously.

Course objectives include:

  • Describe the operation of an ON delay timer
  • Describe the operation of an OFF delay timer
  • Draw the standard NEMA schematic symbols for ON and OFF delay timers.
