The M9203‑xxx‑2(Z) Series Electric Spring‑Return Actuators provide control of dampers in HVAC systems. All actuators in this series provide 27 lb‑in (3 N‑m) rated torque. A mechanical spring‑return system provides rated torque with and without power applied to the actuator.
The series includes the following control options:
On/Off, 24 V, 85 to 264 VAC power
On/Off and Floating Point, 24 V power
Proportional, 24 V power, for 0(2) to 10 VDC or 0(4) to 20 mA Control Signal
These actuators are configured for direct mounting and do not require a damper linkage. Actuators can be mounted directly to a damper shaft from 1/4 to 1/2 in. (6 to 12 mm) diameter with a universal clamp. An accessory crank arm and remote mounting kit are available for applications where the actuator cannot be direct‑coupled to the damper shaft. An optional line voltage auxiliary switch indicates an end‑stop position or performs switching functions within the selected rotation range.
