AC6A3CD Fireye Actuator

Overview

The Fireye AC6A3CD is a high-performance rotary actuator designed for precise, modulating control in industrial burner and valve systems. As part of the AC Series, this keypad-programmable, direct-coupled motor converts electrical signals into accurate rotational motion to regulate fuel and combustion air. This specific model features a 120V power requirement and is configured for horizontal mounting with the display keypad and wiring connections oriented to the right (90-degree RH orientation).

Features

• Solid-state electronics for reliable and repeatable performance.
• Keypad programmable with an LED display and membrane keys for easy local manual control and parameter settings.
• Direct-coupled, modulating motor design eliminates the need for complex linkages.
• Multiple control signal inputs including 4-20mA, 0-10Vdc, and isolated digital contacts.
• Two auxiliary contacts provided for precise position feedback.
• Selectable clockwise or counterclockwise rotation to suit various valve and damper configurations.
• NEMA 4 rated construction for durability in demanding industrial environments.

Applications

The AC6A3CD is primarily used in industrial burner management systems and combustion control applications. It is engineered to provide precise positioning for air dampers and fuel control butterfly valves to maintain optimal air-to-fuel ratios. Common applications include commercial and industrial boilers, furnaces, and process heating systems where reliable thermal efficiency and emission control are critical. It serves as a modern replacement for obsolete actuators like the Eclipse PRA series.
