    Solid State Surface-Mount Timer Relays

    Attach these relays to a flat surface using the mounting hole. They have no moving parts, so compared to mechanical switches, they require less maintenance, last longer, and are quieter.
    Delayed Start (Delay on Make)—Delayed start (delay on make) relays allow you to set how long it takes for the relay to turn on after input voltage is applied. For example, a drill starts pumping a lubricant immediately, but it does not start rotating until the set time has elapsed.
    Delayed Switch Off (Delay on Break)—Delayed switch off (delay on break) relays activate with a switch instead of input voltage. When the switch is turned off, the relay remains on for a programmed amount of time before turning off. For example, a projector’s light is turned off with a switch, but its cooling fan continues to run for a set time.
    Interval—Interval relays use input voltage to turn on for a programmed amount of time. For example, when a part moving down a conveyor reaches a certain location, a cleaning spray comes on for a set time.
    Repeat Cycle—Repeat cycle relays turn on for a duration, then off for the same duration. They alternate between the two cycles until input voltage is removed. A common example would be a flashing light.
    Switch on (Single Shot)—Switch on (single shot) relays require a switch to activate the relay. They’ll stay on for a programmed amount of time. For example, lights in a storage room are turned on with a switch and stay on for a set time before turning off.
    Potentiometer—Switches with a potentiometer (variable switch) allow you to adjust the delay within the range.
