DIN-Rail Mount Touch-Safe Screw Terminal Relays

Quickly and safely mount these relays on 35 mm DIN rail (also known as DIN 3). IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits.

Relays that control 3 and 4 circuits are built to IEC dimensional standards and are often called IEC contactors. Those with 12 terminals let you attach the control circuit onto the side that works best for your setup, which reduces the amount of wire you need.

Auxiliary contacts (sold separately) allow you to add a signaling device or control another relay. You can add one auxiliary contact to all of these relays. For relays with 12 terminals, you can add two side-mount auxiliary contacts.

Use replacement coils to swap out a broken coil or change the input voltage of a relay. They are only compatible with relays that have 12 terminals. The full load current of the relay must match the full load current range of the coil.

Safety Relays

Receive signals from safety monitoring relays or controllers to switch devices off and on because of a system failure. Also known as force-guided or mechanically linked contacts, the interlocking opposing contacts on these relays cannot be open or closed at the same time. To keep your system from receiving false switching signals, the interlocking opposing contact must remain open even if a contact welds closed.

IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits. These relays have been tested to safety standards that can help you achieve your system's PL (performance level) and SIL (safety integrity level). Choose a relay with a PL and SIL rating to meet the needs of your system. Higher ratings indicate greater safety protection. As your system becomes more complex, you generally require a higher safety protection level. Mount them to 35mm DIN rail (also known as DIN 3 Rail).

Relays that meet SIL2 are tested for applications with a probability of failure of 0.1% to 1%. They’re often used for emergency shutdowns, and fire, gas, and overpressure detection. Relays that meet SIL3 are tested for applications with a probability of failure of 0.01% to 0.1% and are used for preventing fires, explosions, or toxic releases. Relays that meet CAT 4 withstand circuit surges in electrical applications up to 600V.

When a failure is detected, relays with self-monitoring circuitry signal the controller to remove power and prevent restarting until the issue is resolved.

Relays with nondetachable contacts have auxiliary contacts that won’t separate from the relay if there is shock or vibration. Relays with mirror auxiliary contacts have contacts that are normally closed and cannot be open at the same time as a normally open main contact.

Machine-Guard Relays

The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding. The screw terminals are recessed to prevent accidental contact with live connections. Mount them on 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces. These relays are built to IEC dimensional standards.

Auxiliary contact (sold separately) allows you to add a signaling device or control another relay.

Interface Safety Relays

These relays pair the transmission reliability of an interface relay with the fail-safe operation of a safety relay. Use them to communicate signals to devices like motors or sensors. They have interlocking contacts—also known as force-guided or mechanically linked contacts—so opposing contacts won't close at the same time. This minimizes the chance of arcing, so electricity won't jump across the contacts and interfere with your relay or system. They also have an interface that isolates input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal. Mount them on 35 mm DIN rail (also known as DIN 3 rail). The relays disconnect from the socket for quick replacement.

Relays with LED indicator light up when the relay is on, so you’ll know it’s wired correctly and can tell at a glance whether it’s on or off.
