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.

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.
