Product Information

Full details

This Finder 46.52 DPDT relay is designed for industrial applications requiring reliable switching of DC circuits up to 8A. Its compact size and versatile mounting options make it suitable for space-constrained control panels. A key benefit is its robust construction and high isolation voltage, ensuring operational safety. However, users should note that it requires a 24VDC coil power source, limiting its direct integration into AC systems without a converter.

FAQs

What is the maximum AC voltage the contacts can switch?

The contacts are rated for a maximum of 250VAC.

Can this relay be used with AC control signals?

No, the coil is designed specifically for 24VDC. Using an AC signal will likely damage the relay. A DC power supply or converter is required.

What type of contacts does this relay have?

It features DPDT (Double Pole Double Throw) contacts, also known as dual changeover contacts.

How can I manually test the relay without energizing the coil?

The relay includes a lockable test button that allows you to manually move the contacts to their energized position for testing purposes.

What are the dimensions of the relay?

The compact dimensions are 29mm (width) x 12.4mm (depth) x 32.8mm (height).

What mounting options are available?

It can be directly mounted, or mounted using a flange adaptor or a 35mm rail mounting screw socket.

What is the isolation voltage between the coil and contacts?

The isolation voltage is 6000VAC, providing a high level of safety.

Troubleshooting

Relay does not energize when coil voltage is applied.

Verify the coil voltage is exactly 24VDC. Check wiring connections to the coil terminals for proper polarity and secure attachment. Ensure the control signal is present and at the correct voltage level.

Contacts are not switching (stuck open or closed).

Manually operate the lockable test button to check for mechanical issues. Ensure the coil is receiving the correct voltage to activate the switching mechanism. If the contacts are pitted or damaged, the relay may need replacement.

Overheating of the relay.

Ensure the connected load does not exceed the 8A rating. Verify that the coil voltage is correct; over-voltage can cause overheating. Check for proper ventilation around the relay.

Intermittent operation or failure.

Check for loose wiring connections, especially in high-vibration environments. Ensure the operating temperature is within the specified range (-40°C to +70°C). Consider potential electromagnetic interference affecting the coil signal.

Pros and Cons

Pros

  • Compact and space-saving design.
  • Versatile mounting options (direct, flange, or rail mount).
  • High electrical isolation for enhanced safety.
  • Lockable test button simplifies manual operation and diagnostics.
  • Durable construction suitable for industrial environments.

Cons

  • Requires a 24VDC coil power supply, not directly compatible with AC systems.
  • Limited to 8A switching current, may not be suitable for very high-power loads.
  • Requires appropriate mounting accessories for rail or flange mounting.
  • Contact material (AgNi) may be less suitable for extremely high-frequency switching compared to other types.

Setup, Compatibility & Care

Setup:

  1. Mounting: The relay can be directly mounted using screws, or with optional flange mount adaptors or 35mm rail mounting screw sockets (e.g., Finder 97.01 series). Ensure secure mounting to prevent vibration-related issues.
  2. Wiring: Connect the 24VDC coil terminals to the appropriate power source. Wire the DPDT contacts according to your circuit diagram, ensuring proper connection to the loads and control signals.

Compatibility:

  • Coil Voltage: Primarily designed for 24VDC control systems. Use a voltage converter if integrating into systems with different voltage standards.
  • Load Type: Suitable for switching resistive and inductive loads within its 8A rating at 250VAC. For AC loads, ensure the voltage does not exceed 250V.
  • Environmental: Operates reliably between -40°C and +70°C. Ensure proper ventilation if used in enclosed spaces within this temperature range.

Care:

  • Cleaning: Keep the relay clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid solvents.
  • Inspection: Periodically inspect wiring connections for signs of corrosion or looseness. Check the mechanical indicator for proper operation.
  • Environment: Avoid exposing the relay to excessive moisture, corrosive atmospheres, or extreme vibration beyond its operational specifications.
