## Summary description

The Phoenix Contact 2987943 is a high-quality industrial electrical relay designed for reliable switching applications. This 2-pole relay operates at 24V DC with an 8A current rating. It is engineered for integration into control systems and automation panels, providing efficient signal isolation and power switching. Its compact design ensures compatibility with standard industrial mounting configurations.

## Long description

The Phoenix Contact 2987943 is a high-performance plug-in miniature relay engineered for demanding industrial switching applications. This 2-pole relay features two changeover contacts (2 PDTs) and is designed to operate reliably with a 24V DC input voltage. It serves as a critical component in control systems and automation panels, facilitating efficient signal isolation and power switching with an 8A current rating. The device is equipped with a test button for manual operation, a mechanical switch position indicator for visual status monitoring, and an integrated status LED for clear operational feedback.
Advantages
This relay offers exceptional reliability and ease of maintenance in industrial environments. The inclusion of a test button allows for quick system diagnostics without the need for external power, while the mechanical position indicator and status LED provide immediate visual confirmation of the relay state. The built-in freewheeling diode protects sensitive control electronics from voltage spikes, ensuring a longer service life for both the relay and the connected components. Its compact plug-in design simplifies installation and replacement, making it an ideal choice for space-constrained automation cabinets.
Suitable for
Industrial automation and control systems
Signal isolation in electrical circuits
Power switching in control panels
Diagnostic and maintenance testing of electrical systems
This relay may not be suitable for high-voltage applications exceeding its rated capacity or for environments where extreme vibration or moisture levels exceed the specified protection class of the mounting base. It is designed specifically for DC control circuits and should not be used in AC-only systems without appropriate conversion.
Key specifications
Input voltage: 24V DC
Contact configuration: 2 PDT (2-pole)
Maximum current rating: 8A
Integrated features: Test button, mechanical position indicator, status LED, freewheeling diode
Polarity: A1+, A2
To use the relay, insert it into a compatible socket base designed for plug-in miniature relays. Ensure that the polarity is correctly matched to the A1+ and A2 terminals to prevent damage to the internal diode. Once seated, the relay can be tested manually using the integrated test button. The status LED will illuminate when the coil is energized, and the mechanical indicator will show the current contact position. Always ensure the power is disconnected before installing or removing the relay from the socket.
What to consider before purchase
Verify that your control system provides a 24V DC signal.
Ensure the socket base is compatible with the 2-pole plug-in configuration.
Check that the 8A current rating is sufficient for your specific load requirements.
Confirm the physical space availability within your control cabinet for the relay and its base.
For optimal performance and longevity, ensure the relay is installed in a clean, dry environment and that all electrical connections are tightened securely to prevent overheating.
