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.

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.

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. Surface mount controllers let you mount controllers on equipment such as tanks and conveyors. By mounting them on your equipment, you save space in your control cabinet. They use M12 connectors.

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. IP66 rated components withstand washdowns. 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.

Mount these indicators to your equipment, and their bright LED will catch your attention when it’s time for maintenance or inspection. They’re commonly used to keep track of maintenance on production lines and HVAC systems, or paired with inspection tags on fire extinguishers and eye wash stations.

When first set, these indicators flash a dark green and then a light green color every two minutes. As a scheduled inspection approaches, they flash a yellow light every 10 seconds. And when an inspection is past due, they blink red every two seconds. Reset indicators to start the countdown again. They meet IP65, so they seal out dust and low-pressure washdowns.
