## Long description

The Phoenix Contact REL-MR-24DC/21-21 is a high-performance industrial power relay engineered for reliable switching in demanding control and automation systems. This compact, pluggable miniature relay is designed to provide consistent performance in electrical circuits, ensuring precise signal and power management. Built to meet rigorous international standards, it serves as a robust component for industrial infrastructure where space-saving and durability are essential.
Advantages
This relay offers exceptional reliability due to its monostable design and high-quality contact materials. Its compact form factor allows for efficient use of space within control cabinets and on printed circuit boards. The device is capable of handling significant switching loads while maintaining operational stability across a wide temperature range. Furthermore, its compatibility with standard relay sockets facilitates easy installation and maintenance, reducing downtime in critical industrial applications.
Suitable for
Industrial automation and control systems
Signal switching in electronic circuits
Integration into control cabinets and relay modules
General-purpose power management tasks
This relay may not be suitable for applications requiring high-frequency switching beyond its mechanical life specifications or for environments with extreme vibration levels that exceed standard industrial ratings. It is also not intended for direct high-voltage power distribution outside of its rated switching capacity.
Key specifications
Coil voltage: 24V DC
Contact configuration: 2 changeover (DPDT)
Maximum switching voltage: 250V AC/DC
Maximum switching current: 8A
Maximum switching power: 2000 VA
Operating temperature range: -40°C to +85°C
Coil resistance: 1440 Ohm
Connection type: Solder pins
The relay is designed for mounting onto compatible relay sockets or direct soldering onto printed circuit boards. Ensure that the coil voltage matches your control system output of 24V DC before installation. When inserting the relay into a socket, verify that the pins are aligned correctly to prevent damage to the terminals. Always disconnect power from the circuit before performing any installation or replacement tasks to ensure operator safety.
What to consider before purchase
Verify that the 24V DC coil voltage matches your control circuit requirements
Ensure the 8A maximum switching current is sufficient for your connected load
Check that the physical dimensions and solder pin configuration are compatible with your existing socket or PCB layout
Confirm the environmental conditions do not exceed the specified temperature range of -40°C to +85°C
Usage recommendations: For optimal longevity, ensure the relay is protected from excessive moisture and dust. When switching inductive loads, it is recommended to use external suppression components to protect the relay contacts from arcing and extend the operational lifespan of the device.
