Spade-Terminal Relays

Relay-Socket Mount

Relay-Socket/Surface Mount

Relay Socket with Screw Terminals

Using a low-current signal, these relays are often used to control small motors and heaters. These relays attach to quick-disconnect terminals.

Surface-mount relays have a slot on the flange for mounting them to flat surfaces. Relay-socket mount relays plug into a socket (sold separately).

Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relay sockets with screw terminals can also mount to a flat surface.

Solid State DIN-Rail Mount Multifunction Timer Relays

4 Circuit Control

For fast installation, mount these relays to 35 mm DIN rail (also known as DIN 3 rail). They also mount to flat surfaces. With no moving parts, these solid state relays last longer and require less maintenance, are quieter, and switch faster than mechanical relays. They provide a variety of timing functions in one relay.

Use relays with DIP switches for more precise control than knobs. They make it easier to set multiple relays to the same timing range.

Relays that control 4 circuits require a relay socket (sold separately) to attach to DIN rail.
