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.

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

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

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

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

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

Mount these timer relays directly to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Unlike mechanical relays, they have no moving parts, so they require less maintenance and last longer, are quieter, and switch faster.

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.

Save electricity and extend motor life by reducing the motor's starting current.

Mount these monitors to DIN rail.

To prevent accidents, these switches won’t let your machine start running unless two people in different locations coordinate control.
