Belimo DKRX24-MFT-T Actuator

The Belimo DKRX24-MFT-T is a high-torque electronic fail-safe actuator engineered for precise control in demanding HVAC applications. Operating on a 24V AC/DC power supply, this unit delivers a formidable 810 in-lb (90 Nm) torque output, making it suitable for large butterfly valves and heavy-duty dampers. The Multi-Function Technology (MFT) allows for field-adjustable parameters, including control input, feedback signals, and running time, providing maximum flexibility for complex sequences of operation. Built with a NEMA 2 (IP54) rated enclosure and a brushless DC motor, it ensures long-term reliability under continuous load without the risk of motor burnout. The integrated electronic fail-safe mechanism utilizes internal capacitors to drive the actuator to a user-defined safety position during power loss, ensuring system protection in critical environments. For contractors requiring proportional control and high-force actuation, the DKRX24-MFT-T is a robust solution for rigorous commercial retrofits and new builds.

• Field-Adjustable MFT: Customize control signals (0-10 VDC, 2-10 VDC, or floating point) and feedback to match specific system requirements.
• High Torque Output: Provides 810 in-lb of force to reliably operate large-scale mechanical components.
• Electronic Fail-Safe: Capacitor-driven safety return ensures predictable positioning during power interruptions.
• Terminal Block Connection: Simplifies wiring for fast field installation and maintenance.
• Synchronized Operation: Optimized for parallel mounting on a single shaft when additional torque is required.

Common Questions

What is the typical running time for the DKRX24-MFT-T?
The default motor running time is 150 seconds, though this can be adjusted via MFT software to meet specific application needs.

Can this actuator be used in outdoor environments?
The standard housing is NEMA 2 rated. For outdoor applications or exposure to severe weather, a protective NEMA 4X weather shield is required.

How do I configure the fail-safe direction on this model?
The fail-safe position (Open, Closed, or a specific percentage) is field-selectable using the Belimo PC Tool or the internal DIP switches.
