DARE Electronics combines advanced state-of-art timing circuits with solid-state or electromechanical outputs to manufacture a complete line of high-reliability time delay relays. This line includes many various precision timing relays commonly referred to as:

  • one-shot timers

  • repeat cycle timers

  • recycle time delay relays

  • solid-state timers

  • interval timers

  • watchdog timers

  • motor driven timers

These time delay relays, available in variety of standard & custom options as illustrated in the above photo and on our time delay relay product datasheet, provide the option of a fixed time-delay or an adjustable time-delay with the time delay on operate (pull-in) and/or the time delay on release (drop-out) and normally-open or normally-closed contacts.

Models are available with:

  • Time delays ranging from milliseconds to hours

  • Operating voltages of:
    18 – 32 Vdc (28 Vdc nominal) or
    105 to 125 Vac (115 Vrms nominal) 50Hz, 60 Hz, or 400 Hz

  • Relay contact configurations in:
    SPDT, DPDT, 3PDT, 4PDT, or 6PDT, and

  • Relay contact ratings of:
    2 amp, 5 amp, 10 amp, or 25 amps

If you are not sure whether you need a delay on operate (pull-in), a delay on release (drop-out), an interval timer, repeat cycle timer, fixed or adjustable time delay relay, consult our time delay relay operation sheet for more information about each of the various types of time delay relays.

For typical specifications and standard enclosures & wiring connections, see our time delay relay product datasheet or contact a sales engineer for assistance with your time delay relay requirements. DARE’s sales engineers would be happy to work with you to design a one-shot timer, repeat / recycle timer, solid-state, interval or watchdog timer specifically for your application or help you determine which one of the various time delay relay models is right for your application.

For example, many customers use a time delay relay with a delay on pull-in (operate) to protect sensitive, critical equipment during system power-up by providing a brief time delay during start-up until the system is fully energized. In addition, a time delay relay may be used for event sequencing or instrumentation control or in an alarm circuit or watchdog circuit. Sometimes two time-delay relays are used in conjunction with each other to provide a pulsing or flashing of a lamp. These two time delay relays can be combined internally into one time delay relay, commonly known as a flasher or repeat cycle timer.

Further, while time delay relays have many applications in a variety of industries, DARE’s time delay relays are primarily designed to meet the severe environmental requirements of the military and aerospace industry. As such, most DARE time delay relays, repeat/re-cycle timers, interval timers, solid-state time delay relays, and watchdog timers are considered mil-spec relays, since they were designed to meet or exceed the requirements of various military specifications, such as MIL-R-83726 (now MIL-PRF-83726), MIL-STD-704, and MIL-STD-810. If your time delay relay needs do not require such stringent military or aerospace specifications and standards, please be sure to let us know, so we can offer the most appropriate time delay relay.
