Schneider Electric RXG21BD Interface Relay, 24V DC, 5A, 2 C/O Contacts

The Schneider Electric RXG21BD is a high-performance interface relay engineered for reliable switching in industrial control environments. Operating with a 24V DC coil voltage and supporting a 5A current rating, this compact component features two changeover (C/O) contacts, making it a versatile choice for managing electrical signals in automation systems. Its robust design and adherence to international safety standards ensure consistent performance and longevity in demanding applications.

Advantages

This interface relay offers exceptional reliability due to its high-quality construction and compliance with global safety certifications including UL 508 and IEC 61810-1. The compact form factor allows for efficient use of space in control cabinets, while the dual changeover contacts provide flexible configuration options for complex circuit designs. Its lightweight build and standardized electrical characteristics make it an easy-to-integrate solution for both new installations and maintenance upgrades.

Suitable for

• Industrial automation and control systems
• Signal switching in electrical panels
• Automation tasks requiring precise control
• General purpose electrical interface applications

When it may not be suitable

This relay is not intended for high-power switching applications exceeding its 1250 VA load capacity or 5A current limit. It is also not suitable for outdoor environments or areas with high moisture levels, as it carries an IP40 protection rating, which does not provide protection against water ingress.

Key specifications

• Coil voltage: 24V DC
• Contact configuration: 2 C/O (Double Pole Double Throw)
• Maximum current: 5A
• Load capacity: 1250 VA
• Protection rating: IP40
• Dimensions: 13 mm width, 29 mm depth
• Weight: 20 g

How to use

The relay is designed for installation within a compatible socket or directly into a control circuit board. Ensure the coil voltage matches the 24V DC supply before connection to prevent damage. Secure the relay firmly in its base and verify that all wiring connections are tight and correctly mapped to the contact terminals. Once installed, the relay will automatically switch the connected circuits based on the activation of the coil.

What to consider before purchase

• Verify that your control system provides a 24V DC supply.
• Ensure the load requirements of your application do not exceed 5A or 1250 VA.
• Check the available space in your enclosure to accommodate the 13 mm width.
• Confirm that the environment is dry and free from dust or moisture to maintain the IP40 rating.

Usage recommendations

Always disconnect the power supply before installing or replacing the relay to prevent electrical shock. Ensure that the relay is used within its specified electrical ratings to maintain safety and operational efficiency.
