Finder 55.34.8.230.0040 Industrial Miniature Plug-in Relay, 230V AC, 7A, 4PDT

The Finder 55.34.8.230.0040 is a high-performance industrial miniature plug-in relay engineered for precision switching in automation and control systems. This component features four changeover contacts and is designed to operate reliably with a 230V AC coil voltage. Built for durability, it includes a mechanical indicator and a test button, making it a versatile solution for demanding electrical environments.

Advantages

This relay stands out due to its robust construction and high switching capacity, which ensures consistent performance over long operational cycles. The inclusion of a test button allows for easy manual verification of circuit status during maintenance, while the mechanical indicator provides clear visual feedback on the relay's state. Its compact design facilitates efficient use of space in control panels, and the high-quality contact material ensures reliable electrical conductivity and longevity.

Suitable for

• Industrial automation and control systems
• Electrical panel integration
• Switching of auxiliary circuits
• HVAC control systems
• Machine tool control

When it may not be suitable

This relay is not intended for high-power applications exceeding its 7A rated current or 1750 VA switching capacity. It is also not suitable for direct outdoor installation without a protective enclosure, as it is designed for controlled industrial environments.

Key specifications

• Coil voltage: 230V AC
• 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: 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 into a compatible socket. Ensure the power supply is disconnected before inserting or removing the relay. Once seated, the coil terminals should be connected to the 230V AC control circuit. The load circuits are connected to the corresponding contact terminals. The test button can be used to manually actuate the contacts for testing purposes when the coil is not energized.

What to consider before purchase

• Verify that your control circuit voltage matches the 230V AC coil requirement.
• Ensure the load current does not exceed the 7A limit.
• Check that your socket is compatible with the 2 mm flat pin configuration.
• Confirm the environmental conditions are within the specified temperature range.

Usage recommendations

Always ensure that the relay is properly secured in its socket to prevent vibration-related disconnection. Regularly inspect the contacts and the relay housing for signs of wear or environmental damage in high-duty cycle applications.
