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.

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.

Note: Sockets may have extra holes on their face that are not used.
