M9310-HGA-2 Johnson Controls Actuator

Overview

The Johnson Controls M9310-HGA-2 is an electric non-spring return damper actuator designed to provide reliable control of dampers and valves in commercial HVAC and building automation systems. Operating on a 24 VAC/VDC power supply, it delivers a rated torque of 88 to 90 lb-in (10 N-m) and features Automatic Signal Input Detection to seamlessly recognize on/off, floating, and proportional control modes. The actuator is engineered for easy direct-coupled mounting without the need for complex damper linkages.

Features

• Automatic Signal Input Detection automatically adjusts to on/off, floating, and proportional control signals
• Direct-coupled design allows universal clamp mounting directly to round or square damper shafts
• Microprocessor-controlled brushless DC motor provides a constant runtime independent of torque load
• Electronic stall detection protects the internal gears from overload across all rotation angles without mechanical end switches
• Mode configuration switches permit easy calibration, input signal range selection, and control logic reversal
• Includes a 120-inch (10 ft) plenum-rated cable with colored and numbered conductors for simplified field wiring

Specifications

• Torque: 88 to 90 lb-in (10 N-m)
• Power Requirements: 24 VAC (19.2 to 28.8 VAC) at 50/60 Hz, 4.7 VA running; 24 VDC (21.6 to 28.8 VDC), 1.3 W running
• Control Input Signal: On/Off, Floating, or Proportional 0(2) to 10 VDC (adjustable span and offset)
• Position Feedback: 0(2) to 10 VDC (available during proportional mode)
• Rotation Range: Mechanically limited from 35 degrees to 95 degrees, adjustable in 5-degree increments
• Runtime: 90 seconds constant for 90 degrees of travel
