AC6A2CD Fireye Actuator

Overview

The Fireye AC6A2CD is a keypad-programmable, direct-coupled, modulating rotary actuator designed for precise control in industrial burner and valve systems. As part of the Fireye AC series, it is engineered to regulate process temperatures by adjusting the position of air or gas dampers and butterfly valves. This specific model is configured for inverted mounting, meaning it is designed to be installed upside-down with the wiring connections at the top, while still providing clear digital feedback and manual control via its integrated interface.

Features

• Keypad Programmable: Allows for local field adjustments of travel limits, sensitivity, and rotation direction without external tools.
• Direct-Coupled Design: Mounts directly to valve stems to eliminate linkage slop and ensure repeatable, accurate positioning.
• LED Display: Provides a real-time digital readout of the current position (0 to 90 degrees) and direction of travel.
• Solid State Electronics: High-reliability internal components housed in a rugged NEMA 4 rated enclosure suitable for boiler room environments.
• Versatile Inputs: Supports 4-20mA, 0-10Vdc, and digital switch inputs for flexible integration with burner management systems.
• Auxiliary Contacts: Includes two internal auxiliary switches for position feedback and interlocking.

Applications

The Fireye AC6A2CD is primarily used in industrial and commercial combustion systems to maintain precise air-to-fuel ratios. It is commonly applied to air dampers and butterfly valves in burner control systems. Its inverted mounting configuration makes it ideal for installations with specific space constraints or existing piping layouts where standard upright mounting is not feasible. It serves as a modern, digital replacement for legacy Eclipse rotary actuators and is typically driven by PID temperature controllers or burner management platforms.
