JOHNSON CONTROLS M9108-AGA-2 Electric Actuator, 70 In.lbs Torque, 24 VAC Voltage, Floating

Johnson Controls M9108-AGA-2 electric actuator is used to regulate airflows and fluid flows, ensuring optimal performance and energy efficiency. Its electric operation allows for accurate positioning and remote control, enhancing system responsiveness and ease of management. This electric actuator is utilised for precision control of valves and dampers in HVAC systems, industrial processes and building automation.

Working Mechanism:

• M9108-AGA-2 electric actuator operates through an electric motor that drives its rotational movement. Powered by 20 to 30 VAC at 50/60 Hz or 24 VDC, it responds to an input signal, often 24 VAC at 50 / 60 Hz or 24 VDC, adjusting through preset terminal configurations.
• As the motor activates, the actuator's output shaft rotates, transferring motion to connected valves or dampers.
• Position feedback mechanisms, such as potentiometers, provide real-time position data. This feedback ensures closed-loop control, aligning actual positions with desired ones. Electronic stall detection safeguards against obstructions.

Features:

• Johnson Controls M9108-AGA-2 electric actuator has rotation capabilities of 0 to 90 degrees in 5-degree increments and it can be operated at temperatures ranging from -4 to 120 degrees F.
• This electric actuator features output position feedback for simple closed-loop control along with accurate position sensing.
• It has direct coupling to reduce installation time and eliminates damper linkages to improve reliability.
• This electric actuator has master / slave operation to ensure synchronised control for two actuators.
• It is equipped with feedback signals of 135 ohms or 1000 ohms (AGD and AGE) to offer accurate position sensing for closed-loop control.
• This electric actuator has screw terminals for secure electrical connection.

Frequently Asked Questions:

Q. How do I adjust the input signal for the actuator's rotation?

A. The input signal adjustment is accomplished through specific terminal configurations. Terminals 1 and 2 provide clockwise rotation, while terminals 1 and 3 provide counterclockwise rotation, which is preset at the factory.

Q. Are there any troubleshooting tips for common issues with this M9108-AGA-2 electric actuator?

A. Common issues may involve checking power connections, input signals and mechanical obstructions to ensure smooth operation.
