Compact Spade-Terminal Relays
Fit these relays where standard spade-terminal relays are too big. You can connect them three ways. Plug them into a socket (sold separately), connect them with quick-disconnect terminals, or solder wires directly to the terminals. An LED indicator shows you the status of the relay, so you know it’s connected and wired correctly.
Relays that control 2 or more circuits have a lockable test button, so you can test their function. When you press the button, the relay switches contacts. Use this button when checking a relay for proper function before installing it, or when investigating issues with wired relays.
Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. You can also mount them to a flat surface using screws.

DIN-Rail Mount Multifunction Timer Relays
Control multiple timing functions from your electrical cabinet—these timer relays mount to 35 mm DIN rail (also known as DIN 3 rail), which is the most commonly used size. UL Listed, C-UL Listed, or CE Marked, these relays meet American, Canadian, or European safety standards.
Timer relays with delayed, interval, switch-on, and repeat cycles have a broad range of applications. Use them to precisely control machines such as conveyors, lighting systems, and electric motors.

Delayed Start (Delay-on-Make)—This function allows you to set how long it takes for the relay to turn on after input voltage is applied. For example, a drill starts pumping lubricant immediately, but it does not start rotating until the set time has elapsed.
Delayed Switch-Off (Delay-on-Break)—This function uses 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.
Delayed Switch-On with Delayed Switch-Off—This function uses a switch instead of input voltage. It allows you to set how long the relay takes to turn on after a switch is turned on, and how long it will stay on after the switch is turned off. For example, a furnace turns on, but the fan doesn’t start pushing air through the vents until it has been heated. When the furnace turns off, the fan keeps blowing to circulate all the hot air.
Delayed Pulse—This function uses input voltage to turn on the relay for a brief period after a preset time. For example, a light flashes a few seconds after a door closes.
Interval—This function uses input voltage to turn on the relay 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.
Interval Switch-Off—This function requires a switch to activate the relay, which stays off for the 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.
Switch-On (Single-Shot)—This function requires a switch to activate the relay, which stays on for the 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.
Repeat Cycle—This function starts with an on cycle and then alternates between an on cycle and off cycle of equal durations until input voltage is removed. A common example would be a flashing light.
Start-Off Repeat Cycle—This function starts with an off cycle and alternates between an on cycle and off cycle of equal durations until input voltage is removed. A common example would be a flashing light.
Switch Fixed On/Off—This function requires a switch to activate the timing function instead of the input voltage (which is applied the entire time). It keeps the relay on whenever the switch is closed; it will only turn off if the switch is open.
