AC6A3AA Fireye Actuator

Overview

The Fireye AC6A3AA is a precision-engineered rotary actuator designed for industrial burner management and combustion control systems. This keypad-programmable, direct-coupled modulating motor is primarily used to regulate process temperatures by accurately positioning dampers and butterfly valves. The unit features a rugged NEMA 4 enclosure, making it suitable for demanding industrial environments like power plants and manufacturing facilities. Its design eliminates mechanical linkage hysteresis, ensuring high-resolution feedback and repeatable fuel-to-air ratio control for efficient combustion.

Features

• Direct-coupled mounting eliminates mechanical slop and increases repeatability
• Integrated LED display with a 4-position orientation keypad for local manual control and parameter setting
• Support for multiple positioning inputs including 4-20mA, 0-10Vdc, and digital switch inputs
• Two auxiliary contacts for position feedback and selectable clockwise or counterclockwise rotation
• Robust NEMA 4 construction provides protection against dust and moisture
• Solid-state electronics for reliable, long-term performance in high-demand boiler rooms
