It is specifically designed to operate with Honeywell Series 90 electronic controllers using a 0…135 Ω resistive input, allowing accurate damper positioning without additional signal converters. The actuator features electronic overload protection throughout its rotation range, ensuring reliable operation and long service life. Its compact housing, selectable direction of motion, and pluggable mechanical position indicator support efficient installation and commissioning. Key Features Resistive Control Compatibility: Designed to accept a 0…135 Ω input signal, enabling direct integration with Honeywell Electronic Series 90 controllers and similar legacy control platforms. 180 In-Lb Torque Output: Provides consistent 20 Nm torque suitable for reliable actuation of HVAC dampers under varying load conditions. Multi-Functional Feedback Output: Supplies a variable 2…10 V position feedback signal for real-time monitoring and integration with building management systems. Electronic Overload Protection: Protects internal components across the full rotation range by preventing damage caused by mechanical obstruction or excessive load. Adjustable Rotation and Speed: Allows mechanical adjustment of rotation angle up to 90° and variable running time between 90 and 150 seconds for optimized damper control. Selectable Direction of Motion: Motor rotation direction can be configured via onboard switch, simplifying installation and reducing setup errors. Manual Override Function: Equipped with an external push button to enable manual positioning during commissioning or maintenance activities. Durable Protected Housing: Rated IP54 and NEMA 2, ensuring reliable operation in typical mechanical room and air-handling unit environments. The ARX24-MFT95 delivers the reliability and precision required for accurate resistive-signal damper control in commercial HVAC applications.
