AC6A3CA Fireye Actuator

Overview

The Fireye AC6A3CA is a high-performance, 120 VAC rotary actuator designed for industrial burner management and combustion control systems. As a keypad-programmable, direct-coupled modulating motor, it provides precise positioning of dampers and valves to regulate air and fuel flow. This actuator is engineered to eliminate mechanical linkage hysteresis, ensuring accurate and repeatable fuel-to-air ratio control in boilers, furnaces, and process heating applications. Its compact design features an integrated LED display and membrane keypad, allowing for easy local setup and manual override.

Features

• Direct-coupled mounting eliminates mechanical slop and increases repeatability in burner dampers and butterfly valves.
• Keypad programmable for setting minimum/maximum travel positions, auxiliary contact points, and rotation direction.
• Integrated LED display with membrane keys for local position indication and manual control.
• Multiple control inputs including 4-20mA, 0-10Vdc, and isolated digital switch inputs for flexible positioning.
• Two auxiliary contacts provide isolated voltage-free feedback for external position monitoring.
• NEMA 4 rated construction offers a robust enclosure protected against dust and moisture in industrial environments.
• 90-degree right-hand (RH) orientation specifically designed for horizontal mounting with wiring connections to the right.

Applications

The AC6A3CA is primarily used in commercial and industrial combustion systems to regulate process temperatures by controlling airflow and fuel supply. It is ideal for parallel positioning systems where high resolution and precision are required to maintain tight setpoints, particularly in low NOx burner applications. Common installations include direct connection to butterfly valve stems and burner air dampers in boilers and furnaces. It integrates seamlessly with Fireye burner management systems, such as the Nexus and PPC6000 series, to streamline digital communication and system setup.
