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.

Quickly and safely mount these relays on 35 mm DIN rail (also known as DIN 3). IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits.

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

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

With no moving parts, these solid-state relays are fast switching and require less maintenance, last longer, and are quieter than mechanical switches.

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

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.

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.

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

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

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

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

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.

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

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.

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

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

Operate equipment that cycles on and off from your control cabinet.

Switch lighting systems on and off—these relays can handle the high switching current on large overhead light systems.

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

Detect and mitigate ground faults to prevent harm to equipment, circuits, and people.
