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.​
