Schneider Electric Harmony RXM2LB2BD Miniature Relay, 24V DC, 5A, 2 C/O Contacts

The Schneider Electric Harmony RXM2LB2BD is a high-performance miniature industrial relay engineered for reliable switching within complex control circuits. This plug-in component is designed for seamless integration into automation systems, providing precise signal management through its 24V DC coil and 5A current rating. Featuring two changeover (C/O) contacts, the relay ensures consistent operation in demanding industrial environments.

Advantages

This relay offers exceptional visibility and ease of maintenance due to its transparent cover and integrated mechanical indicator, which uses an orange flag to display contact status. The inclusion of a bright green LED provides clear status signaling during both day and night operations. Its compact, plug-in design facilitates quick installation and replacement when paired with a compatible socket, while the robust construction ensures long-term reliability in various industrial applications.

Suitable for

• Industrial automation control panels
• Packaging and textile machinery
• HVAC and lighting control systems
• PLC interfaces and motor control circuits
• Low and medium voltage switchgear
• Medical and building equipment

When it may not be suitable

This relay is not intended for high-power switching applications exceeding its 5A current rating. It is also not suitable for direct outdoor installation without additional protective enclosures, as it carries an IP40 rating which does not provide protection against water ingress or heavy dust accumulation.

Key specifications

• Control circuit voltage: 24V DC
• Contact configuration: 2 C/O (changeover)
• Rated current: 5A
• Mounting type: Plug-in (requires RXZE socket)
• Status indication: Mechanical orange flag and green LED
• Protection rating: IP40
• Weight: 33 g

How to use

To install the relay, insert it firmly into a compatible RXZE1M2C socket. Ensure the orientation matches the pin configuration to avoid damage. Once seated, the relay can be secured using a metal retaining clamp if the installation is subject to vibrations. The device is ready for operation once the 24V DC control voltage is applied to the coil terminals. The status of the contacts can be monitored visually via the transparent cover or the integrated LED indicator.

What to consider before purchase

• Ensure the control system voltage matches the 24V DC specification.
• Verify that a compatible RXZE socket is available for mounting.
• Consider the use of a metal retaining clamp if the equipment is located in a high-vibration environment.
• Confirm that the 5A current capacity is sufficient for your specific load requirements.

Usage recommendations: For optimal performance and safety, always ensure the relay is installed in a clean, dry environment. Regularly inspect the contacts for signs of wear if the relay is subjected to high-frequency switching cycles. Use only with approved Schneider Electric sockets to maintain system integrity and compliance with international standards.
