Johnson Controls M9116-AGC-2 Actuator

The Johnson Controls M9116-AGC-2 is a robust, non-spring return actuator designed for the precise positioning of air dampers and valves within commercial HVACR systems. Delivering a steady 140 lb-in torque, this unit is the direct replacement for D24-140-A, ensuring seamless integration into existing control setups. Engineered for versatile field performance, it supports 24Vac/Vdc floating control or two-position (on/off) logic, providing technicians with the flexibility required for varying sequence of operations. This model features manual gear release for rapid commissioning and electronic stall detection to protect the brushless DC motor without the need for limit switches. The inclusion of two integrated SPDT auxiliary switches allows for reliable end-stop signaling or auxiliary equipment interlocking. With a 70-115 second travel time and durable screw terminals, the M9116-AGC-2 serves as a reliable solution for direct coupled actuator applications requiring long-term industrial durability and consistent rotation control.

• Direct Compatibility: Operates as the official replacement for the D24-140-A, utilizing the same footprint and 140 lb-in torque rating for hassle-free retrofits.
• Advanced Motor Protection: Integrated electronic stall detection automatically deactivates the motor if an obstruction is met, preventing internal gear damage.
• Simplified Commissioning: Features a manual override button and a clear position indicator to streamline damper actuator installation and field testing.
• Flexible Signal Handling: Accommodates both floating point control and basic two-position wiring, compatible with a wide range of BAS controllers.
• Integrated Feedback: Two internal SPDT auxiliary switches provide precise end-of-stroke verification for enhanced system monitoring.

Is the M9116-AGC-2 compatible with both AC and DC power?
Yes, this Johnson Controls actuator is designed to operate on a 24V supply, functioning reliably with either 24Vac or 24Vdc inputs.

Can I use this actuator as a fail-safe (spring return) model?
No, the M9116-AGC-2 is a non-spring return motor. In the event of a power loss, the actuator will maintain its last position. For applications requiring a return to 'normal' position on power loss, a spring-return series such as the M9210 or M9220 should be used.

How do I adjust the rotation range on this unit?
The stroke can be limited mechanically using the onboard 5-degree increment scale. This allows you to calibrate the 70-115 second travel time and rotation to match specific damper blade requirements.
