Relpol R4N Industrial Relay 4P 220V DC AgNi/Au with LED and Test Button

The Relpol R4N industrial relay is a high-performance 4-pole electromechanical component engineered for demanding control and automation environments. Designed for precision and durability, this relay ensures reliable signal switching in complex electrical systems. It features a 220V DC coil and is equipped with AgNi/Au contacts, which provide superior conductivity and resistance to oxidation, ensuring long-term operational stability.

Advantages

This industrial relay stands out due to its robust construction and user-friendly design features. The inclusion of an integrated LED indicator allows for immediate visual status monitoring, significantly reducing troubleshooting time. Furthermore, the lockable test button provides a convenient way to manually verify circuit functionality during installation or maintenance without needing to energize the coil. The use of gold-plated silver-nickel contacts ensures reliable performance even in low-current applications, making it a versatile choice for various industrial automation tasks.

Suitable for

• Industrial machinery control systems
• Power distribution and management panels
• Automation and process control logic
• Signal switching in electrical cabinets

When it may not be suitable

This relay is specifically designed for 220V DC control circuits. It is not suitable for applications requiring AC coil operation or for systems where the voltage levels exceed the specified ratings. Additionally, it should not be used in environments with extreme vibration or corrosive atmospheres that exceed the component's protection class.

Key specifications

• 4-pole changeover contact configuration
• 220V DC coil voltage
• AgNi/Au contact material
• Integrated LED status indicator
• Lockable manual test button

How to use

The relay is designed for standard mounting within control panels, typically utilizing a compatible socket. Ensure the power supply is disconnected before installation. Insert the relay into the socket, ensuring the pins are correctly aligned. Once installed, the LED indicator will illuminate when the coil is energized. To perform a manual test, use the lockable test button to actuate the contacts, ensuring the mechanism is returned to the automatic position after testing is complete.

What to consider before purchase

• Verify that your control circuit voltage matches the 220V DC coil requirement
• Ensure the socket used is compatible with the R4N relay pin layout
• Check the current and voltage load requirements of your application

Usage recommendations

Regularly inspect the relay for signs of wear or dust accumulation in industrial environments. Ensure that the test button is returned to its original position after manual maintenance to prevent unintended operation.
