Phoenix Contact REL-MR-BL-24DC/21-21 Single Relay – 24 V DC Coil, 2 Change-over Contacts (DPDT), Plug-in Miniature Power Relay – Item 2906286

Detailed Description:

The Phoenix Contact REL-MR-BL-24DC/21-21 (Item No. 2906286) is a high-quality plug-in miniature power relay engineered for industrial control applications, offering a 24 V DC coil and dual change-over (DPDT) contacts for switching two separate circuits.

Key Features & Benefits:

• 24 V DC nominal coil voltage – compatible with standard industrial control circuits.

• Two change-over (DPDT) contacts: allows switching two independent circuits (commonly used for dual-path or mirrored control schemes).

• Compact plug-in format simplifies installation and service replacement.

• Designed for industrial use: robust construction and reliable performance in demanding control panels.

• High switching capability: supports switching of AC/DC loads up to the rated limits of the contact set. For example, in a similar variant “-21” double contact version ratings: limiting continuous current up to ~8 A, max inrush ~16 A for 20 ms. T

Typical Applications:

• Interface between PLC/logic outputs and higher-power field loads when two circuits must be switched simultaneously.

• Compact control cabinets, machine tool panels, automation systems where space is constrained but dual-circuit switching needed.

• Replacement of relays in modular socket systems in automation control systems.

Installation & Use Notes:

• Ensure coil supply is 24 V DC as required for correct actuation.

• Verify that the load currents for each contact do not exceed the recommended limiting continuous current (e.g., ~8 A) and inrush current conditions (e.g., ~16 A for short duration) as with equivalent version. 

• Use the correct socket or base compatible with the plug-in relay.

• Ensure ambient temperature and installation environment meet manufacturer’s defined limits (for similar relay types: e.g., -40 °C to +70 °C operation). 

Scope of Delivery:
