Relays

Spade-Terminal Relays

Using a low-current signal, these relays are often used to control small motors and heaters.

DIN-Rail Mount Interface Relays

Prevent damage from voltage spikes, reduce signal interference, and amplify signal with these relays, which interface between your controller and components to isolate input and output circuits.

Circular-Pin Relays

The circular pin terminals plug into relay sockets for easy installation.

PCB-Mount Relays

Solder these relays directly to printed circuit boards using their solder pin terminals.

Open-Style Relays

These relays are rated for motors with 1-3 horsepower or 15-90 amps—use them with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.

Hazardous Location Relays

Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.

Washdown Relays

A NEMA 4X enclosure protects the relay from washdowns, dirt, and corrosion. It has wire leads to hardwire to your equipment.

Alternating Relays

Split run time between two devices—these relays automatically alternate between them.

Latching Relays

A single, momentary input voltage switches these relays and locks them in position, so they don't require a constant input voltage to stay on or off.

Timer Relays

Turn machinery, such as paint and conveyor lines, on and off after a set period of time.

Dual-Channel DIN-Rail Mount
Multifunction Timer Relays

Control two steps of an electrical process from a single relay—with two fully independent channels and 30 different functions, these relays give you a wide range of possibilities.

Multifunction Timer Relays

Get a variety of timing functions in a single relay.

Solid State Versa-Mount Multifunction Timer Relays

Install these relays in a panel cutout or plug them into a relay socket. Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, are quieter, and switch faster.

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.
