AC6A1AD Fireye Actuator

Overview

The Fireye AC6A1AD is a high-performance rotary actuator designed for precise control in industrial burner and valve management systems. As part of the AC Series, this keypad-programmable, direct-coupled modulating motor is engineered to regulate process temperatures by accurately positioning air or gas dampers and butterfly valves. The unit features a specialized upright mounting configuration and a fixed 75-degree stroke, making it a critical component for maintaining thermal efficiency in commercial and industrial boiler applications.

Features

• Keypad programmable interface for easy customization of travel limits and rotation parameters.
• Direct-coupled modulating motor providing smooth, precise control of fuel and airflow.
• Solid-state electronics ensuring high reliability and a long service life with reduced maintenance.
• LED display with membrane keys for real-time position indication and local manual control.
• Multiple signal compatibility including 4-20mA, 0-10Vdc, and digital switch inputs.
• NEMA 4 rated construction for protection against harsh industrial environments.
• Two auxiliary contacts included for essential position feedback to the main control system.

Applications

The AC6A1AD is primarily used in burner management systems (BMS) to manage fuel-air ratios in commercial and industrial boilers. It is ideally suited for controlling air dampers and butterfly valves where a specific 75-degree mechanical travel is required. By providing repeatable angular accuracy, it helps optimize combustion, reduce emissions, and improve overall fuel efficiency. It is commonly found in HVAC systems, mechanical equipment rooms, and industrial thermal process environments that utilize Fireye flame safeguard controls.
