4. Especificacions

5. Instal·lació i configuració

The Eltako KR09-230V Switching Relay is designed for DIN rail mounting within an electrical enclosure or control panel. Ensure that the installation environment is dry and free from excessive vibrations.

1. Desconnexió d'alimentació: Before beginning any installation, ensure that the main power supply to the circuit is completely disconnected and locked out to prevent accidental re-energization.
2. Muntatge: Snap the relay onto a standard 35mm DIN rail. Ensure it is securely fastened.
3. Cablejat: Connecteu el control voltage (230V AC) to terminals A1 i A2. The relay's internal coil will be energized by this voltage.
4. Connexió de càrrega: Connect the circuit to be switched to terminals 1 i 2. These are the normally open (NO) contacts. When the control voltage is applied to A1/A2, the contacts between 1 and 2 will close, allowing current to flow through the connected load.
5. Verificació: Comproveu dues vegades totes les connexions del cablejat per assegurar-vos que siguin correctes i estan ben ajustades. Assegureu-vos que no hi hagi cables pelats al descobert.
6. Restauració d'energia: Un cop verificades totes les connexions, restableu l'alimentació del circuit.

Refer to local electrical codes and standards for specific wiring requirements.

6. Funcionament

The Eltako KR09-230V functions as a simple switching relay:

• When 230V AC control voltage is applied to terminals A1 i A2, the relay coil energizes.
• Upon energization, the normally open contacts between terminals 1 i 2 close. This completes the circuit for the connected load, allowing power to flow.
• When the 230V AC control voltage s'elimina de A1 i A2, the relay coil de-energizes.
• The contacts between 1 i 2 then return to their normally open state, breaking the circuit and turning off the connected load.

This relay is suitable for applications requiring remote switching of loads, signal isolation, or simple control logic within electrical systems.

7. Manteniment

The Eltako KR09-230V Switching Relay is designed to be maintenance-free under normal operating conditions. Regular inspection of the terminals for tightness and signs of overheating is recommended as part of routine electrical system checks.

If the device shows signs of damage or malfunction, it should be replaced by a qualified professional.

8. Solució De Problemes

Si el relé no funciona com s'espera, tingueu en compte els següents problemes comuns:

• Relay does not switch:
  • Check if the 230V AC control voltage is correctly applied to terminals A1 and A2.
  • Verify that the control voltage està dins de l'interval especificat.
  • Inspect wiring for loose connections or breaks.
• Load does not receive power when relay switches:
  • Ensure the load circuit is correctly wired to terminals 1 and 2.
  • Check the load itself for faults.
  • Verify that the load current does not exceed the relay's 6A rating. Overcurrent can damage the contacts.
• Sobreescalfament:
  • Ensure the load current is not exceeding the maximum rating.
  • Comproveu si hi ha connexions de terminals soltes, ja que poden causar resistència i calor.
  • Ensure adequate ventilation around the relay.

For persistent issues, consult a qualified electrician or contact Eltako customer support.
