## Long description

The Phoenix Contact REL-MR-BL-24DC/21HC is a high-performance miniature relay engineered for demanding industrial control and automation environments. This single-pole relay is designed to provide robust electrical isolation and reliable signal switching, ensuring consistent performance in complex control circuits. With a 16A switching capacity and durable AgNi contact material, it is built to handle significant electrical loads while maintaining operational integrity over time.
Advantages
This miniature relay offers exceptional reliability due to its high-quality construction and precise engineering standards. The use of silver-nickel contact material ensures excellent conductivity and resistance to wear, making it suitable for frequent switching operations. Its compact design allows for efficient space utilization within control cabinets, while the 24V DC coil voltage makes it compatible with standard industrial automation power supplies. The relay is specifically optimized for seamless integration with ECOR-1 sockets, simplifying installation and maintenance procedures.
Suitable for
Industrial automation systems
Control cabinet signal switching
Power distribution management
Automation interface modules
This relay may not be suitable for applications requiring high-voltage switching beyond its rated capacity or for environments with extreme vibration or temperature conditions that exceed the manufacturer's specified operating range. It is also not intended for use in circuits requiring multi-pole switching configurations.
Key specifications
Coil voltage: 24V DC
Contact configuration: 1-pole (SPDT)
Switching current: 16A
Contact material: AgNi
Compatibility: ECOR-1 sockets
To use the relay, insert it into a compatible ECOR-1 socket, ensuring the pins are correctly aligned with the terminal slots. Once seated, verify that the coil voltage matches your control circuit output. The relay operates automatically when the 24V DC signal is applied to the coil, triggering the internal contact mechanism to switch the connected load.
What to consider before purchase
Verify that your control system provides a 24V DC signal.
Ensure the load current does not exceed the 16A rating.
Confirm compatibility with the ECOR-1 socket system.
Check the physical space constraints within your electrical enclosure.
Usage recommendations
For optimal longevity and performance, ensure the relay is installed in a clean, dry environment protected from excessive dust and moisture. Regularly inspect the socket connections to prevent oxidation and ensure secure electrical contact during operation.
