Timing Alternating & Sequencing Relays

Timing, Alternating, & Sequencing Relays
Timing, Alternating, & Sequencing Relays can be utilized for control of electrical circuits based on specific timing and pattern functions. These relays can open or close their contacts based on time-delay settings, alternating patterns, or designated sequences.


We carry a wide variety of timers with an even wider variety of timing functions. Each timer is ideal for different types of applications depending on timing functions, electrical specifications, and form factor.

  • 12 timing functions



Elko Digital Clock/Calendar
A digital clock/calendar relay will start/stop the motor at specified times and dates based on how it is programmed. Our digital clock/calendar relays accept multiple timings and include holiday and Daylight Savings Time features.

  • 100 settings
  • Universal voltage
  • DIN rail mountable
  • 16A contact rating



Elko MR-4 Latching Relays
Latching relays enable operation of a circuit without maintaining the input power. Once the input power is received, the contacts retain their new position even in the absence of control power.

  • Standard single module width
  • Universal voltage
  • DIN rail mountable
  • 16A contact rating
