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.

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.

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.

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.

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

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

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

Prevent changes in frequency from damaging sensitive equipment.

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.

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

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.

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.

Whether installed in an electrical cabinet or hard-to-reach area, these timer relays are controlled remotely from your smartphone. They connect to your phone via a free downloadable app so you can set time delay ranges, adjust settings, and save programs.

Housed in a durable steel enclosure.

Use the mounting holes to attach monitors to a flat surface.

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.
