Screw Terminal Relays


Use the screw terminals to hardwire these relays. The built-in enclosure protects contacts from dust and dirt. These relays accept voltage drops up to 50% of the rated voltage without switching. They’re often used with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.

Timer Relays


Turn machinery, such as paint and conveyor lines, on and off after a set period of time. These timer relays plug into relay sockets (sold separately) for fast installation and replacement.
Relay sockets mount on 35 mm DIN rail (also known as DIN 3) or flat surfaces.

Solid State Versa-Mount Timer Relays
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.
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.
