AC6B2AA Fireye Actuator

Overview

The Fireye AC6B2AA is a keypad-programmable, direct-coupled rotary actuator designed for use in burner and valve control systems. It serves as a modulating motor typically paired with electronic controls to regulate process temperatures. This specific model (AC6B2AA) is configured for 230V operation with an inverted keypad orientation, allowing for mounting where wiring connections are at the top. The drive shaft connects directly to a butterfly valve stem, providing precise control of fuel or air flow.

Features

• Solid-state electronics for reliable, maintenance-free operation.
• Integrated LED display with membrane keys for local monitoring and manual control.
• 4-position keypad orientation (upright, 90°, 270°, or inverted) to accommodate various mounting needs.
• Multiple input options for positioning, including 4-20mA, 0-10Vdc, and switch inputs.
• Two auxiliary contacts included for position feedback to external systems.
• Selectable rotation direction (clockwise or counterclockwise) via keypad settings.
• NEMA 4 rated construction for protection against harsh industrial environments.

Applications

The AC6B2AA is primarily used in commercial and industrial combustion systems to control butterfly valves and other modulating burner components. It is commonly employed as a replacement for Eclipse PRA actuators. Its programmable nature makes it suitable for regulating process temperatures in boiler applications, furnaces, and ovens where precise valve positioning and feedback are required. It is compatible with a wide range of Fireye burner and combustion controls.
