AC6A4BA Fireye Actuator

Overview

The Fireye AC6A4BA is a keyboard-programmable, direct-coupled rotary actuator designed for precise modulating control in industrial burner and valve systems. This AC Series motor typically interfaces with electronic controllers to regulate process temperatures by adjusting the position of dampers or butterfly valve stems. This specific model features a Left Hand (LH) keypad orientation, allowing for optimal visibility and access when the unit is mounted horizontally with wiring connections to the left.

Features

• Direct-coupled modulating motor designed for burner and valve control systems.
• Solid-state electronics with an integrated seven-segment LED display and membrane keypad.
• Supports multiple positioning inputs, including 4-20mA, 0-10Vdc, and switch inputs.
• Two auxiliary contacts provide position feedback for flame safeguard sequencing.
• Selectable clockwise or counterclockwise rotation with a standard 90-degree stroke.
• NEMA 4 rated construction for durability in demanding boiler room environments.
• Keypad allows local manual positioning and configuration of travel limits.

Applications

The AC6A4BA is primarily used in commercial and industrial combustion systems to control air or gas flow. It is commonly installed on butterfly valves and air dampers to manage fuel-air ratios, helping to optimize thermal efficiency and reduce emissions. Its programmable nature and high repeatability make it ideal for integration with Fireye parallel positioning controllers and other high-end burner management systems where precise low-fire and high-fire positioning is required.
