Circuit Board Safety Relays
 |  |  |
8 Terminals | 10 Terminals | 14 Terminals |
Reduce connection errors on circuit boards that control machine guards and other safety devices. Also known as force-guided contact relays, they have contact pairs that won’t close at the same time, even if contacts stick or weld shut. These relays take up less space on a board than those with electrical wiring because their solder pin terminals mount directly through circuit board holes. Use them to control high-power components, such as fans and heaters, from a low-power circuit.
Mechanical Indicator—Relays with a mechanical indicator show you whether they’re switched on or off with a flag. Peek through the window on the side to quickly check the flag’s position.
Surge Suppression Coverage—Relays with surge suppression coverage protect sensitive electronics from damage and malfunction by eliminating voltage spikes. Switching off a relay can generate surges of 300 to 500 volts, but a diode within these relays suppresses these surges. An LED indicator on these relays lights up when they’re on, so you know at a glance if they’re wired correctly.

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 rail (also known as DIN 3 rail) for fast installation.
These relays use IO-Link, so they 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.
Spring-Clamp-Terminal Wire Connection—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.

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.
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.
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.

Ground-Fault Monitoring Relays
 |  |
Screw Terminals with IO-Link | Spring-Clamp Terminals with IO-Link |
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.
Spring-Clamp-Terminal Wire Connection—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.
IO-Link Communication Protocol—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.

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.
