Honeywell Commercial MS7103A1021

Honeywell Commercial MS7103A1021 is a Diamond Actuator designed for precise damper control in commercial HVAC systems. This versatile actuator operates with 24 VAC or DC power and accepts 2-10 VDC control signals, delivering accurate positioning and reliable spring-return operation.

With 27 lb-in of torque and a direct-coupled design, it pairs with a self-centering shaft adapter for smooth, repeatable damper movement. Built for durability, it supports standard control schemes and easy integration into existing air-handling units.

Designed for commercial HVAC applications, this actuator ensures repeatable damper positioning across wide temperature ranges and withstanding daily cycling. The self-centering shaft adapter simplifies retrofit and reduces installation time, while the durable construction minimizes maintenance for long service life.
