FAQs

What type of contacts does this relay have?

This relay features Double Pole Single Throw Normally Open (DPST-NO) contacts.

What is the required coil voltage for this relay?

The coil voltage required is 8V AC.

Can this relay be used for DC control circuits?

No, this relay is designed specifically for AC control circuits with its 8V AC coil.

What is the maximum current the contacts can switch?

The contacts are rated for a maximum switching current of 20A.

How is this relay mounted?

It is designed for modular mounting on a standard 35 mm DIN rail.

Is this relay suitable for high inrush current loads?

While rated for 20A continuous, always check the specific inrush current requirements of your load against the relay's specifications for optimal performance.

Troubleshooting

Relay does not activate when control voltage is applied.

Verify the control voltage is exactly 8V AC and is correctly wired to the coil terminals. Check for loose connections or a faulty coil.

Contacts are stuck or do not switch.

Ensure the load current does not exceed the 20A rating. Check for any physical obstructions or damage to the contacts. Inspect the control voltage stability.

Intermittent operation.

Check for unstable or fluctuating control voltage. Ensure the ambient temperature is within the operating range. Inspect wiring for intermittent connections.

Pros and Cons

Pros

  • Easy DIN-rail mounting for quick installation.
  • Robust 20A switching capacity suitable for many applications.
  • DPST-NO contact configuration offers flexibility in circuit control.
  • Reliable performance typical of Finder products.

Cons

  • Specific 8V AC coil voltage may require a dedicated or specialized power supply.
  • DPST-NO configuration might not be suitable for all latching or normally closed circuit needs.
  • Limited to AC control voltage, not suitable for DC control circuits.

Setup, Compatibility & Care

Setup:

  1. Ensure the power source provides a stable 8V AC.
  2. Mount the relay securely onto a 35 mm DIN rail in your control panel.
  3. Connect the control circuit to the coil terminals and the load circuit to the contact terminals according to the wiring diagram.
  4. Verify all connections are secure before applying power.

Compatibility:

  • Compatible with standard 35 mm DIN rails.
  • Requires an 8V AC control voltage source. It is not compatible with DC control voltages.
  • Contact ratings are suitable for AC loads up to 20A; consult specifications for specific load types.

Care:

  • Keep the relay clean and free from dust and debris.
  • Avoid exposing the relay to excessive moisture or extreme temperatures.
  • Regularly inspect wiring connections for signs of wear or corrosion.
