Phoenix Contact REL-MR-BL-230AC/21-21 Miniature Relay, 2-Pole, 8A, 230V AC, AgNi Contacts

The Phoenix Contact REL-MR-BL-230AC/21-21 is a high-performance miniature relay engineered for demanding industrial control environments. This 2-pole component is designed to handle a switching current of 8A and operates on a 230V AC coil voltage, providing reliable switching capabilities for various electrical automation tasks. Its robust construction and compatibility with ECOR-1 sockets make it a dependable choice for integration into control panels and complex electrical systems.

Advantages

This miniature relay offers exceptional reliability due to its high-quality AgNi contact material, which ensures consistent electrical conductivity and long-term durability under standard operating conditions. The compact design allows for efficient space utilization within dense control cabinets, while the standardized 2-pole configuration simplifies circuit design and maintenance. By utilizing the dedicated ECOR-1 socket system, users benefit from a secure, vibration-resistant connection that minimizes installation time and enhances overall system safety.

Suitable for

• Industrial automation systems
• Electrical control panels
• Building management systems
• Signal switching in control circuits

This relay may not be suitable for applications requiring high-frequency switching or environments where the coil voltage deviates from the specified 230V AC requirement. It is also not intended for use in high-power motor starting applications that exceed the 8A current rating or for environments with extreme corrosive gases that could degrade the AgNi contacts.

Key specifications

• Coil voltage: 230V AC
• Contact configuration: 2-pole (DPDT)
• Switching current: 8A
• Contact material: AgNi
• Socket compatibility: ECOR-1

How to use

To install the relay, ensure the power supply is disconnected to prevent electrical hazards. Insert the relay into a compatible ECOR-1 socket, ensuring the pins are correctly aligned with the socket terminals. Once seated, verify that the relay is firmly locked in place. Connect the control wiring to the coil terminals and the load wiring to the contact terminals according to your circuit diagram. After installation, perform a functional test to confirm that the relay switches correctly under load.

What to consider before purchase

• Verify that your control circuit provides a 230V AC signal for the coil.
• Ensure the load current does not exceed the 8A limit.
• Confirm that you have the correct ECOR-1 socket for mounting.
• Check the physical space available in your control cabinet for the relay and socket assembly.

Usage recommendations

For optimal performance and longevity, ensure the relay is installed in an environment free from excessive dust, moisture, and extreme temperature fluctuations. Regularly inspect the socket connections for signs of wear or oxidation to maintain reliable electrical contact over the service life of the component.
