AC6A2BA Fireye Actuator

Overview

The Fireye AC6A2BA is a keypad-programmable, direct-coupled rotary actuator designed for precise modulation of dampers and valves in industrial burner and combustion systems. This 120V motor is engineered with an inverted-mount design, making it ideal for installations where wiring connections are preferred at the top. It serves as a modern, direct replacement for obsolete Eclipse PRA6A2BA models, providing a reliable solution for regulating air and fuel flow to optimize combustion efficiency and process temperature control.

Features

• Keyboard-programmable keypad with an LED display and membrane keys for easy on-site calibration of travel limits and rotation direction.
• Direct-coupled mounting eliminates the need for complex linkages, connecting directly to butterfly valve stems to prevent mechanical slop.
• Versatile input compatibility supporting 4-20mA, 0-10Vdc, and switch inputs for positioning.
• Integrated solid-state electronics housed in a rugged NEMA 4 rated enclosure for durability in demanding environments.
• Two auxiliary contacts included for position feedback and signaling.
• Selectable clockwise or counterclockwise rotation with a standard 90-degree stroke.

Applications

The AC6A2BA is primarily used in commercial and industrial heating applications to regulate process temperatures. It is commonly applied to air and gas damper control, as well as butterfly valve positioning within burner management systems. Its inverted design is specifically suited for tight or non-standard configurations where standard upright mounting is not feasible. It is a critical component for maintaining accurate air-to-fuel ratios across the entire firing range of a burner.
