AC6A3BA Fireye Actuator

Overview

The Fireye AC6A3BA is a high-performance rotary actuator designed for precise control of valves and dampers in industrial and commercial burner management systems. This 120V, 90-degree right-hand (RH) rotation unit is a keypad-programmable, direct-coupled modulating motor. It is engineered to integrate with Fireye Nexus and PPC6000 systems to eliminate mechanical linkage hysteresis, ensuring stable burner performance and optimal combustion efficiency.

Features

• Direct-coupled, modulating motor eliminates the need for complex mechanical linkages.
• Keypad-programmable interface with an LED display and membrane keys for local manual control and parameter setting.
• Versatile input support including 4-20mA, 0-10Vdc, and switch inputs for precise positioning.
• Integrated feedback potentiometer provides high-resolution shaft position data.
• Two auxiliary contacts included for additional position feedback.
• NEMA 4 rated construction for durability in demanding boiler room environments.
• Selectable clockwise or counterclockwise rotation to suit various installation needs.
