Overview
The Honeywell M744D1029 is a rotary Modutrol motor actuator engineered for precision damper and valve positioning in commercial HVAC systems. This 90-degree stroke unit delivers 30-second full actuation timing, making it ideal for proportional control of ductwork airflow and building climate zones. The Honeywell M744D1029 employs modulating control architecture to accept analog signals from pneumatic or electronic controllers.
Key Features
- 90-degree fixed stroke for reliable, repeatable damper positioning
- 30-second full-cycle actuation time for responsive damper modulation
- Modutrol design accepts proportional control signals for smooth airflow adjustment
- Die-cast aluminum housing provides durable construction for indoor/outdoor mounted dampers
- Field-installable auxiliary switches available for end-of-travel indication
- Integral spring-return option available for fail-safe damper positioning
