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

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.

Save space in your control cabinet. These narrow relays are often used for low-current switching applications, such as on small motors and pilot lights.

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.

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

Use the screw terminals to hardwire these relays.

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.

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.

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.

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

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.

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

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.

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

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

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

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

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

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

Attach these relays to a flat surface using the mounting hole. They have no moving parts, so compared to mechanical switches, they require less maintenance, last longer, and are quieter.

Considered solid state because they don’t have any moving parts, these timer relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, preventing damage to your components from voltage spikes, amplifying the relay's signal, and reducing signal interference. They have multiple timing functions, so you don’t need to swap out your relay if you want to change their function.

Reduce voltage fluctuations and stress on shafts and bearings when starting up three-phase motors. These timer relays start with motor contacts in a star configuration, then switch to a delta configuration after a set delay.

For fast installation, mount these relays directly to 35 mm DIN rail (also known as DIN 3 rail). With no moving parts, these solid state relays last longer and require less maintenance, are quieter, and switch faster than mechanical 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.

Get a variety of timing functions in a single relay.

Design and operate up to six simultaneous programs without symbols or technical language—the on-screen instructions use simple English.

Mount these monitors to DIN rail.

Upgrade motor starters that use thermal overload protection with these solid-state overloads—they don't use heating elements, so enclosure ventilation and cooling is not required.
