Bray Commercial DM24-210 Actuator

The Bray Commercial DM24-210 is a high-torque, non-spring return electric actuator engineered for precise control of dampers and valves in demanding building automation systems. Delivering 210 in-lb (23.7 Nm) of torque, this unit provides the mechanical force required for large-scale air handling and fluid control. It features 24 VAC/VDC operation and accepts proportional control signals including 2-10VDC and 4-20mA, allowing for seamless integration with modern DDC controllers. This model is a direct technical equivalent to the Johnson Controls M9124-GGA-2 and M9124-GGA-7, offering a reliable cross-reference solution for field replacements. Designed for industrial-grade durability, the DM24-210 includes a built-in auxiliary switch and a manual override handwheel for emergency positioning. The maintenance-free design and NEMA 2 (IP42) enclosure ensure long-term performance in commercial mechanical rooms, reducing the frequency of field service calls and optimizing system uptime.

Key Benefits for HVAC Contractors:

• Direct Compatibility: Functionally identical to M9124-GGA-2 and M9124-GGA-7 for simplified retrofitting.
• High Torque Output: Rated at 210 in-lb to handle high static pressure dampers and heavy-duty valve assemblies.
• Flexible Signal Input: Jumper-selectable 2-10VDC or 4-20mA analog control accommodates various automation protocols.
• Manual Commissioning: Integrated handwheel allows for manual positioning without power during initial setup or power failures.
• Auxiliary Feedback: Includes internal switching to provide position verification for the building management system.

Common Questions Regarding the DM24-210:

Can this actuator replace a Johnson Controls M9124 series?
Yes, the Bray DM24-210 is the direct equivalent to the M9124-GGA-2 and M9124-GGA-7, matching the torque, voltage, and signal requirements exactly.

Does this unit have a spring return for fail-safe operation?
No, this is a non-spring return actuator. It will maintain its last position upon loss of power. For fail-safe applications, ensure your sequence of operations accounts for this or use a spring-return model.

How do I switch between voltage and current control?
The DM24-210 utilizes internal jumpers or DIP switches to toggle between 2-10VDC and 4-20mA inputs, providing field flexibility for different controller outputs.
