Compact Spade-Terminal Relays
Fit these relays where standard spade-terminal relays are too big. You can connect them three ways. Plug them into a socket (sold separately), connect them with quick-disconnect terminals, or solder wires directly to the terminals. An LED indicator shows you the status of the relay, so you know it’s connected and wired correctly.
Relays that control 2 or more circuits have a lockable test button, so you can test their function. When you press the button, the relay switches contacts. Use this button when checking a relay for proper function before installing it, or when investigating issues with wired relays.
Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. You can also mount them to a flat surface using screws.

Safety Relays
Receive signals from safety monitoring relays or controllers to switch devices off and on because of a system failure. Also known as force-guided or mechanically linked contacts, the interlocking opposing contacts on these relays cannot be open or closed at the same time. To keep your system from receiving false switching signals, the interlocking opposing contact must remain open even if a contact welds closed.
IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits. These relays have been tested to safety standards that can help you achieve your system's PL (performance level) and SIL (safety integrity level). Choose a relay with a PL and SIL rating to meet the needs of your system. Higher ratings indicate greater safety protection. As your system becomes more complex, you generally require a higher safety protection level. Mount them to 35mm DIN rail (also known as DIN 3 Rail).
Relays that meet SIL3 are tested for applications with a probability of failure of 0.01% to 0.1% and are used for preventing fires, explosions, or toxic releases. Relays that meet CAT 4 withstand circuit surges in electrical applications up to 600V.
When a failure is detected, relays with self-monitoring circuitry signal the controller to remove power and prevent restarting until the issue is resolved.
Relays with nondetachable contacts have auxiliary contacts that won’t separate from the relay if there is shock or vibration. Relays with mirror auxiliary contacts have contacts that are normally closed and cannot be open at the same time as a normally open main contact.

Hazardous Location Relays
Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.
Relays with screw terminals or spring-clamp terminals are considered interface relays, so they’re placed between your controller and components to isolate the input and output circuits. This means they protect your component from voltage spikes while amplifying the relay’s signal and reducing interference for reliable transmission. They are often used for switching applications, such as small motors and pilot lights. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail). Relays with spring-clamp terminals connect and disconnect to wires without needing to turn screws. With no screws to shake loose with vibration, the terminals hold tight over time.
Relays with circular-pin terminals or quick-disconnect terminals are hermetically sealed—completely air- and watertight—to shield internal parts from gases, moisture, and other contaminants. They plug into relay sockets (sold separately) for easy installation.
Relay sockets mount to 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces.

Network-Enabled Relays
With a built-in web server, these relays can be remotely controlled over any IP network, including the Internet. They connect to your network either wirelessly or with an Ethernet cable (not included). No programming or software is required to operate these relays. Instead, use your web browser to input the relay’s IP address and the website guides you through simple menus and drop-down lists to set your parameters. Alternatively, you can use these relays with a PLC or without a computer at all if you use one relay as a controller for another relay.
Each circuit has a digital input that can be used to control the relay or a remote relay over the IP network. You could also use the digital input to monitor a separate device, such as a push-button or door alarm switch. These relays can be set to automatically restart network devices, such as computers, even when they fail to respond to relay signals. LED indicators let you know if there’s input and output voltage and if the network is connected and active. All meet at least one safety standard.
Mount these relays on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to flat surfaces.
Power over Ethernet (PoE) compatible relays can receive power from PoE cables (not included).
