Product Information

Full details

This Finder Interface Relay, part of the 38 Series, is designed for industrial control applications requiring compact and reliable signal switching. It offers a single changeover contact and a 24V AC/DC coil, making it suitable for automation and control systems. A key benefit is its space-saving 6.2mm width, ideal for dense panel layouts. One caveat is its IP20 rating, meaning it requires protection from dust and moisture in its operating environment.

FAQs

What is the maximum switching current for this relay?

The relay has a maximum switching capacity of 6A at 250VAC.

What type of contact does this relay have?

It features a single changeover (SPDT) contact, meaning it has one common terminal, one normally open terminal, and one normally closed terminal.

Is this relay suitable for outdoor use?

No, this relay has an IP20 rating, which means it is protected against solid objects greater than 12.5mm but offers no protection against water. It should be installed in a protected enclosure.

What is the coil voltage requirement?

The coil can be operated with either 24V AC or 24V DC.

How can I tell if the relay is active?

The relay is equipped with an LED status indicator that lights up when the coil is energized.

What are the physical dimensions of the relay?

The relay measures 6.2mm in width, 87.9mm in height, and 75.6mm in depth.

What material are the contacts made of?

The contacts are made of AgNi (Silver Nickel alloy).

Troubleshooting

Relay does not energize when control voltage is applied.

Verify the control voltage is indeed 24V AC or DC and correctly applied to terminals A1 and A2. Check for loose wiring connections. Ensure the relay is not exceeding its maximum operating temperature.

Contacts do not switch (remain open or closed).

Confirm that the coil is energized by checking the LED indicator. If the LED is on and contacts are not switching, the relay may be faulty or the load might be drawing excessive current. Check load wiring and ensure it is within the 6A limit.

Intermittent operation or failure.

Ensure the operating environment is suitable (within temperature range, no excessive vibration). Check for loose terminal connections. Verify that the control signal is stable and within the specified voltage range.

LED indicator is not lit.

Verify that the correct 24V AC/DC control voltage is applied to the coil terminals (A1/A2). Check for any breaks in the coil circuit wiring.

Pros and Cons

Pros

  • Highly space-efficient due to its narrow 6.2mm profile.
  • Reliable switching with a 6A rating for common industrial loads.
  • Versatile 24V AC/DC coil voltage.
  • Integrated design simplifies installation.
  • Clear LED status indicator aids operation monitoring.
  • EMC protection enhances operational stability.

Cons

  • IP20 rating requires protection from harsh environmental conditions.
  • Only a single changeover contact limits complex switching configurations.
  • Screw terminals may require more careful wiring than push-in types.
  • Maximum operating temperature of +70°C may be limiting in extreme heat applications.

Setup, Compatibility & Care

Setup:

  1. Mount the relay module securely onto a standard DIN rail (35mm).
  2. Connect the control circuit to the coil terminals (A1, A2) respecting the 24V AC/DC supply. Ensure polarity is observed if using DC.
  3. Wire the load circuit to the changeover contacts (e.g., 11, 12, 14) according to the desired switching configuration (normally closed or normally open).
  4. Ensure all screw terminals are tightened securely to prevent loose connections.

Compatibility:

  • Coil Voltage: Compatible with 24V AC or 24V DC control signals.
  • Load: Suitable for loads up to 6A at 250VAC. Verify load type (resistive, inductive) and ensure it falls within these limits.
  • Environment: Designed for industrial environments; requires protection from dust, moisture, and corrosive substances due to its IP20 rating.

Care:

  • Ensure the relay is de-energized before performing any maintenance or wiring changes.
  • Keep the relay and surrounding area clean and free from dust and debris.
  • Periodically check terminal connections for tightness.
  • Avoid exposing the relay to extreme temperatures outside its -40°C to +70°C operating range.
