Outdoor Set-to-the-Minute High-Current Time and Day Activated Switches

Rated NEMA 3R, these rain-tight switches protect against falling liquids and light splashing. More precise than other time and day switches, they program on/off times for equipment down to the exact minute. They control equipment with high currents, such as landscape lighting, pumps, and heaters. A backup battery maintains the program during a power outage.

24-Hr. Timing Cycle—24-hr. switches repeat the same program daily.

7-Day Timing Cycle—Seven-day switches can perform a different program each day of the week.

365-Day Timing Cycle—Seven-day/365-day switches can perform a different program each day of the week or year, and compensate for leap year and daylight savings time. Override regular programming for up to 99 holidays for any length of time. They can also be used to activate equipment such as bells and signals for just a few seconds.

Astronomical Timing—Switches with astronomical timing can be set to turn lights on and off based on sunrise and sunset.

Day Skipper—Switches with a day skipper can be programmed to skip operation for one to six days.

Outdoor Time and Day Activated Switches

24-Hr. Timing Cycle

Designed to work with landscape lighting and filter pumps, these switches turn equipment on and off at a set time and day. They control two devices at once, and have three-prong outlets to plug devices directly into the switch. All have an override to bypass the programmed on/off settings.

24-Hr. Timing Cycle—24-hr. switches repeat the same program daily. Position trippers around the clock dial to set on and off times.

NEMA 3R Enclosure Rating—NEMA 3R rated switches are protected against falling liquids and light splashing.

Light Sensor Control—Switches with light sensor control allow one device to be controlled by the presence or absence of light.

Switch-Contact-Actuated Hour Meters

Screw On

Clip On

No need for a separate power source—these hour meters are powered by internal batteries that last more than 10 years. Often used where power sources aren’t easily accessible, they work well in remote monitoring systems, industrial equipment, and machinery. Wire the hour meter to a relay or switch on your machine so it can receive signals when the machine is running. The total number of hours is shown on the display. Press a button on the meter to reset the time to zero or connect it to a switch or button to reset it from a distance.

Clip On—Clip-on hour meters can be programmed to flash an icon of your choosing after your machine has run for a set number of hours. Similar to the lights on your car’s dashboard, the icons signal maintenance for your oil, oil filter, service, and more.

IP65 Enclosure Rating, NEMA 4X Enclosure Rating, and NEMA 12 Enclosure Rating—Screw on hour meters are IP65, NEMA 4X, and NEMA 12 rated, so they’re protected from dust, water, and splashing oil and coolant.

UL Recognized Component, C-UL Recognized Component, and CE Marked—These meters are UL recognized, C-UL recognized, and CE marked, so they meet American, Canadian, and European safety standards.

Gaskets—Mount them with a gasket (sold separately) to protect against dust, water, and splashing oil and coolant and so they’ll meet NEMA 4/4X, NEMA 12, and IP66 ratings.

Preventative Maintenance and Inspection Indicators

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.

IO Link Connectors

Components Sold Separately

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.

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

Controllers

Surface

Mount

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—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.

IP66 Enclosure Rating—IP66 rated components withstand washdowns.

IP67 Enclosure Rating—IP67 rated components can be temporarily submerged in water.

IP69K Enclosure Rating—IP69K rated components hold up to high-pressure and high-temperature washdowns.

Enclosure Rating—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.

Expansion Modules

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.

IP65 Enclosure Rating—IP65 rated components can be rinsed.

IP67 Enclosure Rating—IP67 rated components can be temporarily submerged in water.

IP69K Enclosure Rating—IP69K rated components hold up to high-pressure and high-temperature washdowns.
