FAQs

What is the purpose of a DPDT relay?

A DPDT (Double Pole Double Throw) relay has two independent sets of contacts. This allows you to control two separate circuits simultaneously, or to switch a single circuit in two different ways (e.g., reversing polarity).

Can I use a 5V or 12V power supply to activate the 6V coil?

It is not recommended. Using a 5V supply may result in unreliable switching or failure to activate. Using a 12V supply will likely damage the 6V coil due to over-voltage.

What is the maximum current this relay can switch?

This relay is rated to switch a maximum of 8 Amperes.

How do I mount this relay on a PCB?

The relay has pins designed for through-hole mounting directly onto a PCB. Ensure the pins are correctly inserted into the corresponding holes and soldered securely.

Can this relay be used for AC loads?

While the DPDT configuration can be used to switch AC circuits, you must ensure the AC voltage and current of the load do not exceed the relay's 8A contact rating. Always refer to the specific datasheet for AC voltage limits.

What happens if I apply AC voltage to the 6V DC coil?

Applying AC voltage to a DC coil will likely result in improper operation, buzzing, and potential damage to the coil.

Does this relay come with a socket?

Typically, this type of relay is designed for direct PCB mounting or use with a separately purchased compatible socket. Please check the product listing or packaging for what is included.

Troubleshooting

Relay does not switch when coil voltage is applied.

Verify the coil voltage is exactly 6V DC and correctly applied to the coil terminals. Check for correct polarity. Ensure the control circuit is providing the necessary voltage and current.

Contacts are stuck or do not make/break connection.

Ensure the load current and voltage are within the 8A rating. Check for any physical obstructions or damage to the contacts. If the relay has been energized for extended periods under load, it may have reached its operational limit. Consider replacing the unit.

Relay chatters or switches intermittently.

The coil voltage may be unstable or insufficient. Check the power supply for fluctuations. Ensure good electrical connections to the coil and contact terminals. Ambient temperature might be outside the operating range.

Excessive heat from the relay.

This could indicate the load current is exceeding the 8A rating. Disconnect power immediately and verify the switched load. Ensure proper coil voltage is applied; over-voltage on the coil can also cause overheating.

Pros and Cons

Pros

  • Compact size saves valuable board or enclosure space.
  • DPDT contacts provide flexibility for controlling two separate circuits.
  • Suitable for a range of applications with its 8A switching capability.
  • Low 6V DC coil voltage is compatible with many common DC power supplies.
  • Durable construction for long-term reliability.

Cons

  • Specific 6V DC coil requirement may not fit all system voltages without additional circuitry.
  • 8A rating might be insufficient for high-power applications.
  • Requires a compatible socket or careful soldering for PCB mounting.
  • Not designed for high-frequency switching applications.

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely mount the relay onto a PCB using its pins or insert it into a compatible socket. Ensure proper alignment to avoid damaging the pins.
  2. Wiring: Connect the control circuit to the coil terminals (pins 13 and 14 for this model, consult datasheet for exact pinout). Wire the load circuits to the appropriate NO (Normally Open) and NC (Normally Closed) terminals along with the common terminal for each pole (e.g., pins 1, 3, 5 for one pole and 2, 4, 6 for the other - verify pinout).
  3. Power: Apply a stable 6V DC power source to the coil terminals. Ensure the polarity is correct.

Compatibility:

  • Coil Voltage: This relay is specifically designed for a 6V DC coil. Using higher or lower voltages, or AC voltage, can damage the relay or prevent it from operating correctly.
  • Contact Ratings: Ensure the current and voltage of the circuits being switched do not exceed the relay's 8A contact rating.

Care:

  • Avoid exposing the relay to excessive moisture, dust, or corrosive environments.
  • Do not exceed the specified coil voltage or contact ratings.
  • Ensure adequate ventilation if the relay is used in a high-current application where it may dissipate heat.
