About Timer Relays

8-Terminal Relay

Relay Socket

Attach quick-disconnect terminals or plug these relays into relay sockets. Also known as ice cube relays.

Relay sockets (sold separately) mount to 35 mm DIN rail or flat surfaces.

Long-Life Surface-Mount Timer Relays

With no moving parts, these solid state relays have an extended service life. Use the mounting hole to attach to a flat surface. A potentiometer (variable switch) adjusts the delay within the range.
