Finder 55.34.8.110.0040 Industrial Plug-in Relay, 110V DC, 7A, 4PDT

The Finder 55.34.8.110.0040 is a high-performance industrial plug-in relay engineered for reliable switching in demanding control and automation environments. This 4PDT component is designed to handle complex circuit requirements with precision, offering four changeover contacts that ensure versatile connectivity. Built for durability and consistent operation, it serves as a critical interface between control systems and high-power electrical loads.

Advantages

This relay stands out due to its robust construction and user-friendly features that simplify both installation and ongoing maintenance. The inclusion of a mechanical test button allows technicians to verify circuit functionality without needing to energize the coil, significantly reducing troubleshooting time. Furthermore, the integrated mechanical operation indicator provides clear visual feedback on the relay status, ensuring that operators can quickly identify active or inactive states during routine inspections.

Suitable for

• Industrial automation and control panels
• Power distribution systems
• Manufacturing machinery and equipment
• HVAC control systems
• Electrical interface applications

This relay may not be suitable for applications requiring high-frequency switching beyond its mechanical life expectancy or in environments where extreme vibration exceeds the specified mounting tolerances. It is also not intended for direct use in high-voltage power transmission lines or circuits that exceed the 250V AC maximum switching voltage rating.

Key specifications

• Coil voltage: 110V DC
• Contact configuration: 4PDT (4 changeover)
• Rated current: 7A
• Maximum switching voltage: 250V AC
• Maximum switching power: 1750 VA
• Operating temperature range: -40°C to +85°C
• Connection type: 2mm flat pins
• Dimensions: 27.7mm x 20.7mm x 37.2mm

To use the Finder 55.34.8.110.0040, insert the relay into a compatible socket designed for 2mm flat pin configurations. Ensure that the coil voltage matches the 110V DC supply of your control circuit. Once installed, the mechanical test button can be used to manually actuate the contacts for testing purposes. Always ensure the power is disconnected before performing any wiring or maintenance tasks to prevent electrical hazards.

What to consider before purchase

• Verify that your control system provides a 110V DC supply for the coil.
• Ensure the socket used is compatible with the 4PDT pin layout.
• Check that the load current does not exceed the 7A rating.
• Confirm the physical space available in your control cabinet for the relay dimensions.

For optimal performance and longevity, ensure the relay is installed in a clean, dry environment and protected from excessive dust or moisture. Regular inspections of the contact points and terminal connections are recommended to maintain system reliability.
