IO Link Controllers and Modules
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.
Expansion modules increase the number of inputs and outputs in your IO Link system, so you can add more sensors and actuators to your network. Connect multiple devices to each expansion module using M12 connectors, without needing to wire your devices inside a control cabinet. They transmit signals from multiple devices with a single cord. Expansion modules are optional, but when used, they must connect to a controller. Mount them on your equipment to save space in your control cabinet.
Protective caps prevent dust and debris from harming M12 connections when they're not in use. They also help maintain IP ratings by covering unused ports. Stainless steel protective caps have a neoprene gasket, which helps maintain IP69K ratings.
IP rated components block out dust and withstand some water, so they do not require an enclosure. Ports that are unused must be capped to maintain their rating. IP65 rated components can be rinsed. IP67 rated components can be temporarily submerged in water. IP69K rated components hold up to high-pressure and high-temperature washdowns.
Note: Sockets may have extra holes on their face that are not used.

Hand-Held IO Link Programmers
Configure any of your IO Link devices—from sensors to switches—without a PC, outlet, or separate software. Use these programmers to set parameters, check the quality of runs, clone settings for other devices, and more. Whether you’re setting up a device for the first time or adjusting settings, the easy-to-use touchscreen makes for a smooth experience. Since these programmers are powered by a battery and small enough to carry, you can bring them wherever you need.
As soon as you connect your device, these programmers download its IO Device Description (IODD) file. This means you won’t need to manually input device details, saving you time to jump right into programming. Internal storage keeps IODD files and custom settings on hand for you. If you need extra space, insert a microSD card (not included) into these programmers before turning on the connected device.
Plug devices with M8 or M12 connections directly into the sockets on these programmers. If your device has wire leads, use the included adapter.

Voltage-Monitoring Relays
Safeguard your equipment against overheating, wear, and malfunction from a spike or dip in voltage. These relays continuously monitor your AC or DC power supply and trip when the voltage is outside a set range. Rated IP20, these relays have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on a 35 mm DIN rail (also known as DIN 3 rail) for fast installation.
Relays with IO link can be programmed, monitored and reset remotely by connecting them to a programmable logic controller (PLC), human-machine interface (HMI), or computer. If you want to program them locally, they have a keypad.
Relays with spring-clamp terminals connect and disconnect to wire without screws. Because there’s no screw, these connections are less likely to loosen over time, even in high-vibration environments.

Multifunction Monitoring Relays
Monitor phase, voltage, and frequency at the same time to protect motors, generators, and other three-phase circuits from burning out or overheating. They'll switch the circuit off if they detect voltage or frequencies outside of the set range or phase loss, imbalance, or reversal. Rated IP20, they have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on a 35 mm DIN (also known as DIN 3 rail) for fast installation.

Current-Monitoring Relays
Protect electrical equipment from overcurrent and undercurrent damage—these relays continuously monitor current flow. When current is outside a set range, they trip and cut power to prevent overheating, fire hazards, and stalling. Rated IP20, these relays have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on a 35 mm DIN rail (also known as DIN 3 rail) for fast installation.

Ground-Fault Monitoring Relays
Detect and mitigate ground faults to prevent harm to equipment, circuits, and people. These relays monitor the differential between incoming and outgoing current, also known as residual current. When the balance is off, they trip and cut power to the circuit. These relays are highly sensitive, so you can trust them to de-energize faulty circuits before a minor issue becomes a major one. Rated IP20, they have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on 35 mm DIN rail (also known as DIN 3 rail) for fast installation.
These relays require a current-indicating ring (sold separately) to operate. Choose a ring that is large enough for your lines to pass through. Feed the lines of the circuit through the center of the ring and connect the indicating ring output to the relay.
Relays with spring-clamp terminals connect and disconnect to wire without screws. Because they don’t have screws, there’s less of a risk that they will loosen over time, even when they’re under vibration.
Relays with IO link can be programmed, monitored, and reset remotely by connecting them to a programmable logic controller (PLC), human-machine interface (HMI), or computer. If you want to program them locally, they have a keypad.
