Isolate input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal.

Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation.

Smaller than relays with electrical wiring, these relays fit in compact devices. Mount them through holes on circuit boards with their solder pin terminals.

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

Often used for high-speed switching at low-current levels, these solid state relays have no moving parts, so they switch faster, last longer, and are quieter than mechanical switches.

For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Also known as definite-purpose contactors.

Use these relays with industrial automation systems, security and emergency lighting, and small motors.

Reduce connection errors on circuit boards that control machine guards and other safety devices. These relays take up less space on a board than those with electrical wiring because their solder pin terminals mount directly through circuit board holes.

The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding.

These relays pair the transmission reliability of an interface relay with the fail-safe operation of a safety relay. They have interlocking contacts—also known as force-guided or mechanically linked contacts—so opposing contacts won't close at the same time.

These relays switch through a series of different circuit configurations every time they receive an input voltage. Also known as step relays.

An extended housing shields the terminals on these relays from weather.

Suitable for DC-powered equipment such as forklifts, floor scrubbers, and trucks.

Sealed to keep out water, these relays are often used for DC-powered equipment such as forklifts, floor scrubbers, and trucks.

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

With a built-in web server, these relays can be remotely controlled over any IP network, including the Internet.

Prevent changes in frequency from damaging sensitive equipment.

Protect electrical equipment from overcurrent and undercurrent damage—these relays continuously monitor current flow.

Remotely control these relays through an app on your smartphone—they simultaneously monitor phase, voltage, and frequency.

Send a signal to turn equipment on and off from up to 150 feet away without having to run electrical wire. These relays have an enclosure to protect the terminals from dust and accidental bumps.

A NEMA 4X enclosure protects these relays from washdowns, dirt, and corrosion.
