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.

With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, which protects components from voltage spikes, amplifies the relay’s signal, and reduces interference for reliable transmission.

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

Use the screw terminals to hardwire these relays.

Fit these relays where standard spade-terminal relays are too big.

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.

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

Receive signals from safety monitoring relays or controllers to switch devices off and on because of a system failure.

Control and diagnose issues with safety-critical circuits.

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.

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

With no moving parts, these solid state relays require less maintenance and last longer, switch faster, and are quieter, than mechanical relays. Also known as automotive relays.

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

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.

An enclosure covers the terminals on these relays to help prevent damage from dust or accidental bumps.

Often used to regulate the speed of AC fans or keep a heater at a set temperature, these relays connect directly to sensors to calculate and adjust output power. This allows you to use an analog input without converting it to a digital signal to control output power.

Monitor phase, voltage, and frequency at the same time to protect motors, generators, and other three-phase circuits from burning out or overheating.

Prevent changes in frequency from damaging sensitive equipment.

Safeguard your equipment against overheating, wear, and malfunction from a spike or dip in voltage.

Also known as an air-to-electric switch, this relay converts an air signal to an electric signal.

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

With a shallower depth than most other starters, these fit in narrow spaces.

Sized to fit in tight spaces, these starters have a shorter height and narrower depth than most other starters.

Rated NEMA 4X, these enclosed starters are protected from corrosion and washdowns.

Housed in a durable steel enclosure.

Operated by hand, these starters are more compact than electrically actuated motor starters; use them when multiple motor circuits are housed in one panel.

Combine a switch and a thermal overload element to build a starter that can handle high-current-rated motors. Also known as a NEMA starter.

Use these switches to turn motors on and off, or with lighting and electric heat circuits. They do not provide overload protection.

These switches are housed in a plastic enclosure.

Start and stop motors outdoors and in other wet environments.

Rated NEMA 4, these switches are protected from washdowns.
