The Johnson Controls M9108-GGA-2 is a non-spring return electric actuator engineered for precise control of dampers and valves in HVAC systems. Operating on 24 VAC or VDC, it supports proportional control signals of 0–10 VDC, 2–10 VDC, and 4–20 mA (with a 500-ohm resistor), making it versatile for various control applications.
This actuator delivers a torque of 70 lb-in (8 Nm) and features an adjustable rotation range from 0° to 90° in 5° increments, with a mechanically limited maximum of 93°. Its travel time ranges between 25 and 50 seconds, providing smooth and reliable operation. The M9108-GGA-2 is designed for direct mounting on damper shafts, accommodating round shafts from 3/8" to 3/4" (10 to 20 mm) and square shafts from 3/8" to 5/8" (10 to 16 mm).
Constructed with durability in mind, the actuator operates within a temperature range of -4°F to 122°F (-20°C to 50°C) and up to 90% relative humidity. It features screw terminal connections for 22 to 14 AWG wires and is rated NEMA 2, ensuring protection against environmental factors. The M9108-GGA-2 replaces part number M9106-GGA-2.
