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.
