Electric Non-Spring Return Actuator M9300 Series

Electric Non-Spring Return Actuator


The Johnson Controls M9300 Electric Non-Spring Return Actuator Series provide control of dampers in HVAC systems. Actuators in this series provide rated torques from 70 lb·in (8 N·m) to 310 lb·in (35 N·m). The series consists of models for on/off and floating control as well as models with Automatic Signal Input Detection, which allows automatic recognition of input signals for on/off, floating, and proportional control. These actuators are configured for direct mounting and do not require damper linkage. Actuators can be mounted directly with a universal clamp to a round damper shaft from 3/8 in. (10 mm) up to 1-1/16 in. (27 mm), and to a square damper shaft from 3/8 in. (10 mm) up to 3/4 in. (19 mm).

No accessories found
  • - Models with Automatic Signal Input Detection, On/Off, Floating, and Proportional Control with Adjustable Span and Offset. Increases availability at distributors and simplifies retrofits.
  • - Line Voltage On/Off and Floating Models. Reduces total installation cost by avoiding installation of external power supply adapters.
  • - High Speed On/Off and Floating Models. Allow applications in loops that require a quick response time.
  • - Easy Conversion to Valve Operation-Same Actuator Used for Dampers or Valves. Increases availability at distributors with only one actuator to learn.
  • - Optional Accessory Kit Increases availability at distributors. The auxiliary switch kit provides two line-voltage-capable single-pole, double-throw (SPDT) switches with continuously adjustable switch points, and the auxiliary potentiometer kit provides several potentiometer feedback options. Facilitates safety interfacing or signaling.
  • - Backward Compatible Auxiliary Switch Kits and Auxiliary Potentiometer. Allows for a seamless retrofit without the need to replace the controller.
  • - Self-Calibrating Input Signal to Adjust Stroke. Eliminates the need for a complex calibration procedure when adjusting stops.
  • - Direct-Coupled Design. Requires no crankarm or linkage.
  • - Electronic Stall Detection Protects from overload at all angles of rotation. The actuator may be stalled anywhere in its rotation range without the need for mechanical end switches.
  • - Microprocessor-Controlled Brushless DC Motor. Provides constant runtime independent of torque and increases lifecycle by reducing wear.
  • - Mode Configuration Switches Permits calibration, input signal range selection, and control logic reversal for proportional control.
  • - Integral Cables with Colored and Numbered Conductors. Simplify installation and field wiring.
  • - Optional Integral 1/2 in. (13 mm) Threaded Conduit Connectors. Simplify installation and field wiring.
  • - Plenum-Rated Models. Enable use in other environmental air spaces (plenums) in accordance with section 300.22(C) of the National Electric Code.
  • - Small Footprint. Allows application in smaller spaces than the M9100 Series Actuators.
  • - NEMA 5/IP54 Enclosure. Enhances the range of application environments.
  • - Underwriters Laboratories Inc.® (UL), CE Mark, and RCM Compliance. Provides internationally recognized regulatory agency approvals.
  • - Manufactured under International Standards Organization (ISO) 9001 Quality Control Standards. Ensures quality.
  • - Bottom-Mounted Coupler. Simplifies short shaft damper applications.
  • - 5-Year Warranty. Protects consumer investment.
