Original Johnson Controls M9108-GDC-1N1 Switch (including M9108,
M9116, M9124, M9132 models) - Field Control Equipment
Product Introduction
The Original Johnson Controls M9108-GDC-1N1 is a field control
equipment switch belonging to the M9108 series, which also includes
M9116, M9124, and M9132 models. With a brand name of Johnson, it is
available at a price of USD120 per piece, with a minimum order
quantity of 1 and a large supply ability of 1000 units. Packaged in
original packaging and with a delivery time of 1 week, it offers
convenient and timely procurement for various industrial needs.
The M9108 series, to which this switch belongs, consists of
proportional electric non-spring return actuators designed for use
in Heating, Ventilating, and Air Conditioning (HVAC) systems. These
actuators are suitable for positioning air dampers and valves,
providing reliable control in various applications.
Product Features
Dual Control Inputs: Meets the needs of most applications, offering
flexibility in integration with different control systems.
Output Position Feedback: Provides simple, closed-loop control with
accurate position sensing through switches, a potentiometer, or a 0
to 10 VDC signal, ensuring precise operation.
Electronic Stall Detection: Enhances reliability by deactivating
the actuator motor if a stall condition is detected, preventing
motor damage.
Dual Scale Cover: Features a dual scale (0 to 90° and 90 to 0°) on
the cover, indicating the actuator’s rotation position in 10°
increments for easy monitoring.
Adjustable Rotation: The removable coupler allows adjustment of the
rotation range from 0 to 90° in 5-degree increments, adapting to
different damper and valve requirements.
Secure Mounting: Equipped with a steel U-bolt clamp that provides
four-point damper shaft gripping, ensuring stable installation on
dampers with round shafts up to 3/4 in. (19 mm) or square shafts up
to 5/8 in. (16 mm).
Easy Setup: Jumper-selectable rotation direction and manual gear
release simplify installation, setup, and field adjustments.
Convenient Connection: National Pipe Thread (NPT) threaded housing
allows easy connection for electrical fittings, facilitating
wiring.
Versatile Mounting: Can be direct- or remote-mounted to a damper,
offering flexibility in installation location.
