Product Information

Full details

This Finder 48 Series interface relay module is designed for electrical professionals and automation engineers needing reliable signal switching. Its key benefit is providing a robust dual changeover contact for load control with a sensitive 12V DC coil. A potential caveat is the need for careful wiring due to its screw terminal connections and the complete assembly requiring separate mounting.

FAQs

What is the maximum switching current and voltage?

The module features dual changeover contacts rated at 8A and 250VAC.

What is the coil voltage for this module?

This module operates on a 12V DC sensitive coil.

Does this module come with a base?

Yes, the complete assembly includes the relay base, relay unit, module, and retention clip.

How is this relay module mounted?

It is designed for standard 35mm DIN rail mounting.

What is the purpose of the freewheeling diode?

The integrated freewheeling diode protects the control circuit from voltage spikes generated by the relay coil when it is de-energized.

Can I use this for switching DC loads?

Yes, you can switch DC loads, but ensure the current and voltage are within the specified limits for the contacts, considering DC characteristics can differ from AC.

What type of contact material is used?

The contact material is AgNi (Silver Nickel).

Troubleshooting

Relay does not energize when control voltage is applied.

Verify the 12V DC supply is present and correctly connected to the coil terminals (A1/A2). Check polarity. Ensure the coil is not internally damaged. Test the supply voltage with a multimeter.

Contacts are stuck or not switching.

Check if the coil is properly energized. Ensure the load current does not exceed the 8A rating. Inspect contacts for signs of welding or heavy contamination, especially if switching inductive loads without adequate protection.

LED indicator is not lit.

Confirm the control voltage is applied correctly to the coil. The LED indicates coil status, so if the coil is not energized, the LED will not light. Check for any breaks in the connection to the LED or internal coil circuit.

Intermittent operation or poor contact.

Ensure screw terminals are tightened securely. Vibration can loosen connections over time. Check for voltage drops across the supply and load lines. Ensure the ambient temperature is within operating limits.

Pros and Cons

Pros

  • Reliable dual changeover contacts for complex switching.
  • Low 12V DC coil voltage for energy efficiency.
  • Integrated LED for clear status indication.
  • Built-in surge protection for coil.
  • Compact and easy to mount on DIN rail.

Cons

  • Requires external wiring for connections.
  • Complete assembly means multiple parts to handle initially.
  • AgNi contact material may not be suitable for all highly corrosive environments without special consideration.
  • Limited to 8A current rating, not for very high power applications.

Setup, Compatibility & Care

Setup:

  1. Ensure the 12V DC power supply is correctly polarized and within specifications.
  2. Mount the complete assembly (relay base, unit, module, clip) onto a standard 35mm DIN rail.
  3. Wire the control circuit to the coil terminals (A1/A2) and the load circuits to the appropriate contact terminals (e.g., 11/12/14 for the first changeover).
  4. Secure all screw terminals firmly.

Compatibility:

  • Designed for use with 12V DC control voltages.
  • Suitable for switching AC loads up to 250VAC and DC loads within its current limits.
  • Compatible with standard industrial control panel environments and DIN rail mounting systems.

Care:

  • Keep the module clean and free from dust and moisture. Use a dry or slightly damp cloth for cleaning.
  • Avoid exposing the module to excessive heat or direct sunlight.
  • Periodically check screw terminal connections for tightness, especially in environments with vibration.
