Mount these timer relays in a panel cutout or plug them into a relay socket for quick installation. Capable of fast switching, they are solid state and have no moving parts, so they require less maintenance, last longer, and are quieter than mechanical relays. Unlike standard relays that switch on and off immediately, timer relays delay before the circuit stops or starts.

Delayed-off relays let you set how long it takes for the relay to turn off after input voltage is removed. For example, a sensor detects when an item has been placed on a conveyor, triggering the relay to start the conveyor belt and a cooling fan. After the item has moved past another sensor, the input voltage is removed to stop the conveyor, while the cooling fan runs for a set time before shutting off.

Relays with a repeat cycle alternate between an on cycle and off cycle of equal durations until input voltage is removed. A common example would be a flashing light.

Relays with an asymmetrical repeat cycle begin in an on state, then alternate between different durations of off and on for as long as input voltage is applied. For example, a heating system starts with an on period, then switches to an off period once the desired temperature is reached.

Relays with a start-off asymmetrical repeat cycle begin in an off state, then alternate between different durations of on and off for as long as input voltage is applied. For example, an irrigation system receives a signal and starts in the off state, allowing water to fill before switching on to start pumping.

Relay sockets (sold separately) mount to 35 mm DIN rail (also known as DIN 3 rail) or can be mounted to a flat surface.

Mounting brackets (sold separately) are required to mount the relay into a panel.
