It supports a wide range of control modes, including proportional voltage, current-based signals, floating point, and on/off operation. The actuator allows configurable start and end points, enabling precise matching to valve stroke and system control requirements. Its compact form factor and integrated cabling make it suitable for installation in space-constrained HVAC control environments. Key Features MFT programmable platform: Enables field configuration of control mode, signal type, operating range, and feedback to match specific system requirements. Non-spring return operation: Provides smooth, motor-driven positioning for applications where fail-safe action is not required. Multiple control modes: Supports 2–10 VDC, optional 4–20 mA, floating point, PWM, and on/off control from a single actuator. Adjustable operating range: Variable start and end points allow precise calibration to valve travel and control strategy. Integrated position feedback: Outputs a configurable 2–10 V signal for accurate position monitoring and closed-loop control. Selectable direction of motion: Motor direction can be set via switch to simplify installation and commissioning. Electronic overload protection: Protects internal components throughout the full rotation range for long-term reliability. The ARX24-MFT delivers the reliability and precision required for programmable, energy-efficient valve control in commercial HVAC and building automation systems.
