AC6A4AA Fireye Actuator

Overview

The Fireye AC6A4AA is a keypad programmable, direct-coupled rotary actuator designed for modulating control in burner and valve systems. This solid-state modulating motor is typically paired with electronic controls to regulate process temperatures by adjusting the position of a butterfly valve stem. The unit features a 90-degree stroke and is configured with a left-hand (LH) display orientation for specific horizontal mounting requirements where wiring connections are preferred on the left.

Features

• Direct-coupled modulating motor for precise valve control
• Integrated LED display with membrane keys for local manual positioning and parameter setting
• Flexible keypad orientation to accommodate various mounting positions and wiring access
• Solid-state electronics ensuring reliable operation without mechanical linkages
• Selectable clockwise or counterclockwise rotation
• Two auxiliary contacts included for position feedback
• NEMA 4 rated construction for durability in industrial environments

Applications

The AC6A4AA actuator is primarily used in commercial and industrial combustion systems to control the flow of fuel or air. It is ideal for mounting directly onto butterfly valve stems to manage process temperatures in burner and valve control systems. Common applications include use in HVAC systems, boilers, and industrial furnaces where it integrates with Fireye flame safeguard and combustion controls to maintain efficient and safe operation.
