AC6A2AA Fireye Actuator

Overview

The Fireye AC6A2AA is a keypad-programmable, direct-coupled, modulating rotary actuator designed for use in industrial burner and valve control systems. Typically used with an electronic control to regulate process temperatures, this AC Series motor provides precise positioning of air and gas dampers or butterfly valves. This specific model is configured for 120 VAC operation and features an inverted keypad orientation, allowing for mounting with wiring connections at the top while maintaining display readability.

Features

• Direct-coupled design eliminates linkage slop for more accurate control.
• Keypad-programmable for easy field adjustment of travel limits and sensitivity.
• LED display with membrane keys for clear status indication and local manual control.
• Solid-state electronics ensure reliable, long-term performance in industrial environments.
• Supports multiple positioning inputs, including 4-20mA, 0-10Vdc, and digital switch inputs.
• Two auxiliary contacts included for position feedback to the burner management system.
• Selectable clockwise or counterclockwise rotation to match valve requirements.
• NEMA 4 rated construction for protection against dust and moisture.

Applications

The Fireye AC6A2AA is primarily used for air or gas damper control and butterfly valve modulation in industrial combustion systems. It serves as a direct replacement for legacy Eclipse PRA6A2AA actuators, enabling seamless upgrades to modern technical standards without extensive cabinet modifications. It is ideally suited for power generation, petrochemical processing, and commercial heating applications where precise air-to-fuel ratio control is essential for thermal efficiency and safety.
