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. Each channel has its own output, so you can run two different functions (one per circuit) at the same time. Mount them to 35 mm DIN rails (also known as DIN 3 rail) and connect them to lighting systems, conveyors, electric motors, and other systems. These relays are UL Listed, C-UL Listed, and CE Marked, meaning they meet U.S. and international safety standards.

View times, function names, and on/off status for both channels at once using the digital display. You can program these relays with a joystick on the face, which is easier to use than the rotary dials on traditional relays. You can also program them using an Android phone with NFC (near field communication) capability, which is commonly used for mobile payment. Once you select the functions you need, hold the phone against the relay to program.

Connect switches to inputs on these relays to trigger, pause, and reset functions. Turning on a switch connected to the pause input stops functions until the switch is turned off. A switch connected to the reset input will start functions from the beginning. If the relay is actively receiving a signal, the function will restart right away. If there is no signal, the function will stop and reset, so it starts from the beginning the next time it’s triggered. You can use switches to pause or reset both channels at once, or for one channel only.

Use relays with proximity sensor compatibility to activate functions when your sensor is triggered, such as when an object approaches or a liquid level changes. These relays are compatible with both standard styles of sensors, PNP and NPN, and are often used for warning signals, motion-detecting light and heating systems, and automated assembly lines.

Although these relays have 30 different functions, they all fall into 10 categories. Within these categories, you can select different functions to allow you to add a switch, program a delay, or change how the relay responds to a trigger (turning on or off, pausing, or resetting).

Manual Switch Control—Use these functions to turn the relay on and off with a switch.

Fixed On/Off—The on function keeps the relay on whenever input voltage is applied; it will only turn off if the voltage is removed. The off function keeps the relay in an off state, even if input voltage is applied.

Switch-On (Single-Shot)—These functions require a switch to activate the relay, which stays on for the programmed amount of time. For example, lights in a storage room are turned on with a switch and stay on for a set time before turning off.

Delayed Start (Delay-on-Make)—These functions allow you to set how long it takes for the relay to turn on after input voltage is applied. For example, a drill starts pumping lubricant immediately, but it does not start rotating until the set time has elapsed.

Delayed Switch-Off (Delay-on-Break)—These functions use a switch instead of input voltage. When the switch is turned off, the relay remains on for a programmed amount of time before turning off. For example, a projector’s light is turned off with a switch, but its cooling fan continues to run for a set time.

Delayed Switch-On with Delayed Switch-Off—This function uses a switch instead of an input voltage. It allows you to set how long it takes the relay to turn on after a switch is turned on, and how long it will stay on after the switch is turned off. For example, a furnace turns on, but the fan doesn’t start pushing air through the vents until it has been heated. When the furnace turns off, the fan keeps blowing to circulate all the hot air.

Interval—These functions use input voltage to turn on the relay for a programmed amount of time. For example, when a part moving down a conveyor reaches a certain location, a cleaning spray comes on for a set amount of time.

Repeat Cycle—These functions alternate between an on cycle and off cycle of equal durations until input voltage is removed, such as with a flashing light.

Asymmetrical Repeat Cycle—These functions alternate between different durations of on and off for as long as input voltage is applied. For example, a sprinkler system sprays in short bursts followed by longer rest periods, on and off until input voltage is removed.

Switch-On Asymmetrical Repeat Cycle—These functions are activated with a switch instead of input voltage. They can be used to turn on a motor or other system for a short period and then turn it off for a longer rest period, repeating that pattern until the switch is turned off.

For fast installation, mount these relays to 35 mm DIN rail (also known as DIN 3 rail). They also mount to flat surfaces. With no moving parts, these solid state relays last longer and require less maintenance, are quieter, and switch faster than mechanical relays. They provide a variety of timing functions in one relay.

Use relays with DIP switches for more precise control than knobs. They make it easier to set multiple relays to the same timing range.

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. After selecting a timing range, use the knob to adjust the trip time within the timing range.

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. Use these relays with switching applications, such as small motors and pilot lights. They offer multiple timing functions in one relay. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relays disconnect from the socket for easy replacement.

Protect components from voltage spikes while amplifying the relay’s signal and reducing interference for reliable transmission—these relays interface between your controller and system components to isolate the input and output circuits. They are often used for switching applications, such as small motors and pilot lights. These relays provide a variety of timing functions in one relay. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relays disconnect from the socket for easy replacement.

Smaller than other PLCs, these controllers save space in your control cabinet. They combine the functionality of a relay, timer relay, and switch in one unit, so you can program simple automation jobs. All have two types of delayed start (delay-on-make) and two types of delayed switch-off (delay-on-break) timing functions. They have passed strict U.S. and Canadian safety standards, and they’re IP20, which prevents fingers and other objects from making contact with live circuits. Mount them to a 35-mm DIN rail.

Controllers with a display make it easy to monitor or modify your system directly on the unit. Controllers without a display eliminate the risk of accidental adjustments while toggling through information or tampering by unauthorized users.

Program these controllers by connecting them to a computer and installing the required software (sold separately). After the initial programming, these controllers can be updated remotely by a human-machine interface (HMI) or computer.

Add expansion modules to increase the number of inputs and outputs. You can connect up to 11 modules to a controller—for a maximum of 188 inputs and outputs. Choose any modules that support the operating voltage of your controller.

Design and operate up to six simultaneous programs without symbols or technical language—the on-screen instructions use simple English. These PLCs combine the functionality of a relay, timer relay, and switch in one unit so you can program complex automation jobs. All have memory backup to retain programming during power outages. Mount to 35-mm DIN rail.

Add expansion modules to increase the number of inputs and outputs. Use either module on its own, or add one of each, but two of the same module won’t work together.

Remote timer panels monitor and adjust up to eight timers while the controller is operating.

No need to program multiple PLCs—these modules expand your automated system, keeping everything conjoined and configured on one processor. Use them when you’re out of space on your DIN rail or need additional input/output functions.

These modules meet NEC safety standards, so they can be used in hazardous locations. They’re also rated IP20 to protect your fingers from touching live wires. Modules are UL and C-UL listed, CE marked, and CSA certified, meeting strict domestic and international safety requirements.

Control modules connect directly to the main PLC rack. Insert them in between the processor and the first input/output module.

Interface modules attach to a separate expansion rack, which requires its own power supply (not included). The interface comes with an end plate, which caps off each rack and ends communication with the processor. A maximum of three expansion racks can be hooked up from the main PLC rack.

Use the expansion cords (sold separately) to connect the control and interface modules together. Cords are also IP20 rated, UL and C-UL listed, CE marked, and CSA certified. Total cord length for your entire system should not exceed 39 ft.

Create a system of sensors and actuators that you can remotely update, view measurements from, and receive error messages in real time. IO Link systems minimize downtime by locating issues such as cut cables or dirty sensors quickly. They send only digital signals to your PLC, regardless of whether your sensors and actuators send digital or analog signals. Because these systems send digital signals, they’re more reliable and less prone to data error and signal loss than analog signals. It also means you don't have to use expensive shielded cables since they resist EMI.

When retrofitting an existing system, you'll need to make sure your PLC can incorporate IO Link. Check with your PLC manufacturer—most have hardware that allows you to upgrade your PLC to run IO Link.

Controllers communicate between your sensors and actuators and your PLC. They are required. Setting memory automatically stores your settings and restores them once your device is back online. This eliminates needing to program a device again when you replace or fix it. DIN-rail mount controllers are designed to mount inside your control cabinet, so you can access all your process control devices in a central location. They include RJ45 Ethernet ports to support JSON and MQTT IoT (Internet of Things) protocols, allowing you to link the system directly to your web server to upload information to the Cloud. Connect these ports with RJ45 cords.

IP rated components block out dust and withstand some water, so they do not require an enclosure.
