    DIN-Rail Mount Touch-Safe Screw Terminal Relays

    Image of Product. Front orientation. Contains Annotated. Relays. 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.
    4 Circuits Controlled—Relays that control 3 and 4 circuits are built to IEC dimensional standards and are often called IEC contactors.
    12 Terminals—Relays 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.

    Use the screw terminals to hardwire these relays. The built-in enclosure protects contacts from dust and dirt. These relays accept voltage drops up to 50% of the rated voltage without switching. They’re often used with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.

    Relay

    Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation. An LED indicator lights up when these relays are connected, so you can quickly confirm that they’re wired correctly. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.
    Integrated Heat Sink—Relays with an integrated heat sink disperse heat to increase the relay’s current rating.

    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).
    SIL 3, PLe, CAT IV, 600V Max. System Safety Rating—DIN-Rail and Surface Mount
    Image of Product. Front orientation. Contains Annotated. Safety Relays. Safety Relays, SIL 3, PLe, CAT IV, 600V Max. System Safety Rating—DIN-Rail and Surface Mount.
    Relays that meet SIL 3 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.
    Mirror Auxiliary Contacts—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.
    Nondetachable Auxiliary Contacts—Relays with nondetachable contacts have auxiliary contacts that won’t separate from the relay if there is shock or vibration.
    Self-Monitoring Circuitry—When a failure is detected, relays with self-monitoring circuitry signal the controller to remove power and prevent restarting until the issue is resolved.

    Operate equipment that cycles on and off from your control cabinet. Often called definite-purpose contactors, these relays meet UL 508 for use with air conditioning and heating. Mount them directly to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They have recessed terminals that prevent fingers and other objects from touching live circuits. You can wire the control circuit on either side of the relay, which helps you use less wire.
