Finder 55.34.9.024.0040 Miniature Plug-in Relay, 24V DC, 7A, 4 Changeover Contacts

The Finder 55.34.9.024.0040 is a high-performance miniature plug-in relay engineered for demanding industrial and automation environments. This monostable relay features a 24V DC coil and is equipped with four changeover contacts, providing versatile switching capabilities for complex electrical circuits. Designed for reliability and ease of use, it includes a lockable test button and a mechanical indicator to simplify system diagnostics and maintenance tasks.

Advantages

This relay offers exceptional durability and consistent performance across a wide temperature range, making it suitable for challenging operational conditions. The inclusion of a lockable test button allows technicians to manually verify circuit functionality without needing to energize the coil, which significantly streamlines installation and troubleshooting processes. Furthermore, the mechanical indicator provides clear visual feedback on the relay status, ensuring that operators can quickly identify whether the device is active or inactive during routine inspections.

Suitable for

• Industrial automation control systems
• Electrical control panels
• Signal management in complex circuits
• Automation equipment requiring multi-contact switching

This relay may not be suitable for applications requiring high-power switching beyond its 1750 VA capacity or for environments where the 7A current limit is insufficient for the connected load. It is also not intended for direct high-voltage DC switching applications that exceed the specified voltage ratings.

Key specifications

• Coil voltage: 24V DC
• Contact configuration: 4 changeover (4PDT) contacts
• Rated current: 7A
• Maximum switching voltage: 250V AC
• Maximum switching power: 1750 VA
• Operating temperature range: -40°C to +85°C
• Connection type: 2 mm flat pins
• Dimensions: 27.7 mm x 20.7 mm x 37.2 mm

How to use

The relay is designed for plug-in installation, typically mounted into a compatible socket. Ensure that the coil voltage matches your control circuit output of 24V DC before installation. Once seated in the socket, the relay can be tested using the integrated lockable test button to confirm contact operation. The mechanical indicator will display the current state of the contacts, allowing for easy monitoring during operation.

What to consider before purchase

• Verify that your control circuit provides a stable 24V DC supply.
• Ensure the total load current does not exceed 7A.
• Check that the socket used is compatible with 2 mm flat pin connections.
• Confirm the physical space in your control cabinet accommodates the relay dimensions.

Usage recommendations: Always ensure the power supply is disconnected before installing or removing the relay from its socket. For long-term reliability, avoid exceeding the maximum operating temperature of 85°C and ensure the relay is protected from excessive moisture or corrosive environments.
