Phoenix Contact REL-MR-BL-230AC/21HC Miniature Relay 1-Pole 16A 230V AC

The Phoenix Contact REL-MR-BL-230AC/21HC is a robust miniature relay engineered for demanding industrial control environments. This 1-pole device is designed to handle a switching capacity of up to 16A, making it a reliable component for power distribution and signal management. Operating on a 230V AC coil voltage, it provides consistent performance in automation systems where space-saving and high-current switching are essential requirements.

Advantages

This relay features high-quality AgNi contacts that ensure excellent electrical conductivity and long-term durability under frequent switching cycles. Its compact design allows for efficient use of space within control cabinets, while the compatibility with ECOR-1 sockets facilitates quick installation and easy maintenance. The device is built to meet rigorous industrial standards, providing a stable and dependable solution for complex electrical circuits.

Suitable for

• Industrial automation control systems
• Power distribution panels
• Switching of high-current loads in control cabinets
• Integration into modular relay interfaces

When it may not be suitable

This relay is not intended for use in environments with extreme vibrations or high levels of corrosive dust, as these conditions may affect the mechanical integrity of the contacts. It is also not suitable for DC-specific applications, as the coil is designed exclusively for 230V AC operation.

Key specifications

• Contact configuration: 1-pole (SPDT)
• Switching current: 16A
• Coil voltage: 230V AC
• Contact material: AgNi
• Socket compatibility: ECOR-1

How to use

To install the relay, ensure that the power supply is disconnected to prevent electrical hazards. Insert the relay into a compatible ECOR-1 socket, ensuring that the pins are correctly aligned with the terminal slots. Once seated, verify that the locking mechanism is engaged. Connect the control wiring to the coil terminals and the load wiring to the appropriate contact terminals according to the 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 16A rating.
• Confirm that you have the appropriate ECOR-1 socket for mounting.
• Check the available space in your cabinet to ensure proper ventilation.

Usage recommendations

For optimal longevity, avoid exceeding the maximum switching capacity and ensure the relay is protected from moisture and extreme temperature fluctuations. Regular inspection of the socket connections is recommended to maintain low contact resistance.
