Product Information

Full details

This Finder 4C Series Interface Relay Module is designed for industrial control systems requiring reliable switching of AC loads. It offers a compact, DIN-rail mountable solution with screw terminals for secure connections and dual changeover contacts. While it provides robust performance, users should be aware of its specific 24VAC coil voltage requirement, which might necessitate a dedicated control transformer.

FAQs

What type of contact configuration does this relay have?

This Finder 4C Series module features two independent changeover (DPDT) contacts.

What is the maximum AC load this relay can switch?

Each contact is rated for a maximum of 8 Amperes at 250 Volts AC.

What is the required coil voltage for this relay?

The coil requires a control voltage of 24 Volts AC (50Hz or 60Hz).

How is the relay mounted?

The relay module is designed for quick and easy mounting onto a standard 35mm DIN rail.

Does the relay come with a base and retaining clip?

Yes, this is a complete assembly that includes the relay base, relay unit, module, and retaining clip.

What does the integrated LED indicate?

The LED serves as a visual indicator for the status of the relay coil; it typically lights up when the coil is energized.

Is this relay suitable for DC loads?

This relay is designed for AC loads. Using it with DC loads may require specific considerations or additional circuitry and is not its intended application.

What is the protection rating (IP) of this module?

The module has an IP20 rating, meaning it is protected against solid objects larger than 12.5mm but has no protection against water. It is suitable for indoor, dry environments within control panels.

Troubleshooting

Relay does not energize when control voltage is applied

Verify that the control voltage is indeed 24VAC and is correctly connected to the coil terminals (A1, A2). Check the control circuit fuse or breaker. Ensure the LED indicator is functioning.

Relay does not de-energize

Ensure the control voltage supply has been removed or switched off. Check for any short circuits in the control wiring. Verify the varistor is not causing a permanent short.

Contacts do not switch load

Confirm the control coil is energized (check LED). Verify the load wiring is correctly connected to the common and the appropriate normally open (NO) or normally closed (NC) contact terminals. Ensure the load current does not exceed the 8A rating.

LED indicator is not lit

Check the 24VAC supply to the coil. Ensure the coil terminals are properly connected. If the coil voltage is correct and the LED still does not light, the relay unit may be faulty.

Overheating of the module

Ensure the module is within its operating temperature range (-40°C to +70°C). Check that the load current does not exceed the 8A rating. Verify adequate ventilation within the control panel.

Pros and Cons

Pros

  • Reliable switching for industrial applications
  • Compact and space-saving DIN rail design
  • Clear status indication via integrated LED
  • Enhanced coil protection with built-in varistor
  • Secure and easy-to-use screw terminal connections
  • Complete module provided for quick installation

Cons

  • Requires a specific 24VAC control voltage
  • Not suitable for DC loads without modification or external circuitry
  • IP20 protection means it's for indoor, protected environments only
  • Limited to a maximum of 8A switching current per contact
  • AgNi contact material may not be suitable for all switching environments (e.g., very high inrush currents)

Setup, Compatibility & Care

Setup:

  1. Mounting: Clip the module firmly onto a standard 35mm DIN rail.
  2. Wiring: Connect the control circuit to the coil terminals (typically marked A1 and A2) using the 24VAC supply. Ensure correct polarity is observed if applicable, though this model is polarity-free for the coil.
  3. Load Wiring: Connect the load circuit(s) to the appropriate changeover contact terminals (common, normally open, normally closed). Refer to the terminal markings on the module.
  4. Verification: Double-check all connections before applying power.

Compatibility:

  • Coil Voltage: Exclusively compatible with 24VAC control circuits. Do not attempt to use with DC or other AC voltages.
  • Load Type: Designed for AC loads up to 8A at 250VAC. Ensure the load's current and voltage ratings do not exceed the relay's specifications.
  • Environment: Suitable for environments with minimal dust and moisture (IP20 rated). Should be installed within control panels or enclosures.

Care:

  • Cleaning: Disconnect all power before cleaning. Wipe the exterior with a dry or slightly damp, lint-free cloth. Avoid using solvents or abrasive cleaners.
  • Ventilation: Ensure adequate airflow around the module when installed in an enclosure to prevent overheating.
  • Periodic Inspection: Visually inspect connections for tightness and signs of corrosion. Check LED functionality periodically.
