Circular-Pin Relays


11-Terminal Relay	Relay Socket for 8-Terminal Relay	Relay Socket for 11-Terminal Socket

The circular pin terminals plug into relay sockets for easy installation. Also known as ice cube relays.

Lockable Test Button—Relays with a lockable test button allow you to test whether a relay is working without an electrical signal. They’re helpful for testing relays before you install them, or for checking that installed relays are working properly.

Horsepower @ Switching Voltage—Relays rated for horsepower (hp) are built to handle tough, repetitive-use applications.

Sockets with Screw Terminals—Relay sockets (sold separately) mount to 35 mm DIN rail (also known as DIN 3 rail) or can be mounted to a flat surface.

Compact Spade-Terminal Relays


11-Terminal Relay	11-Terminal Relay Socket	14-Terminal Relay Socket	8-Terminal Relay Socket

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.

3 Circuits Controlled—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.

Sockets with Screw Terminals—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.

DIN-Rail Mount Interface Relays

Isolate input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal. These relays interface between your controller and components—they receive a signal from the controller to switch power on or off to the components. All have an LED indicator that shows you if your switch is actuated, so you know it’s connected and wired correctly. Use them to communicate signals to devices like motors or sensors. Mount them on 35 mm DIN rail (also known as DIN 3 rail).

Hazardous Location Relays


Circular-Pin Terminals—Hermetically Sealed	Sockets with Screw Terminals

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

Circular-Pin Terminal—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.

Sockets with Screw Terminals—Relay sockets mount to 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces.

Solid State Versa-Mount Multifunction Timer Relays

1 Circuit Controlled

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. They give you a variety of timing functions in one relay.

1 Circuit Controlled—Single-circuit relays give you additional flexibility—they have two types of delayed switch off (delay on break) functions and two types of signal on/off delay functions.

Sockets—Relay sockets (sold separately) mount to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to flat surfaces.

Solid State Versa-Mount Timer Relays


	Sockets

Mount these timer relays in a panel cutout or plug them into a relay socket for quick installation. Capable of fast switching, they are solid state and have no moving parts, so they require less maintenance, last longer, and are quieter than mechanical relays. Unlike standard relays that switch on and off immediately, timer relays delay before the circuit stops or starts.

Asymmetrical Repeat Cycle—Relays with an asymmetrical repeat cycle begin in an on state, then alternate between different durations of off and on for as long as input voltage is applied. For example, a heating system starts with an on period, then switches to an off period once the desired temperature is reached.

Start-Off Asymmetrical Repeat Cycle—Relays with a start-off asymmetrical repeat cycle begin in an off state, then alternate between different durations of on and off for as long as input voltage is applied. For example, an irrigation system receives a signal and starts in the off state, allowing water to fill before switching on to start pumping.

Sockets—Relay sockets (sold separately) mount to 35 mm DIN rail (also known as DIN 3 rail) or can be mounted to a flat surface.
