M9208-GGC-3G Johnson Controls Actuator

Overview

The Johnson Controls M9208-GGC-3G is a proportional electric spring-return actuator designed to control dampers in commercial HVAC systems. It operates on 24 VAC/VDC power and provides 70 lb·in (8 N·m) of running and spring-return torque, ensuring reliable failsafe operation during power interruptions.

Features

• Direct-mount design eliminating the need for a damper linkage
• Two integrated line-voltage SPDT auxiliary switches for position indication
• Brushless DC motor with microprocessor control and electronic stall detection
• Reversible mounting and reduced power consumption in holding mode

Specifications

• Power Supply: 24 VAC/VDC, 8 VA
• Torque: 70 lb·in (8 N·m)
• Control Signal: Proportional 0(2)-10 VDC or 0(4)-20 mA
• Rotation: 95 degrees
• Enclosure: NEMA 2 (IP54)
• Run Time: 150 seconds motor, 17-25 seconds spring return

Applications

• Controls air and control dampers in commercial HVAC systems
• Ideal for building automation setups requiring precise proportional modulation and reliable failsafe spring-return safety functions.
