AC6B1BD Fireye Actuator

Overview

The Fireye AC6B1BD is a high-performance rotary actuator designed for precise modulation in industrial burner and valve control systems. Functioning as a keypad-programmable, direct-coupled motor, this unit is engineered to regulate process temperatures by accurately controlling the positioning of butterfly valves and dampers. Operating on 230VAC, it provides a reliable solution for managing fuel-air ratios, thereby optimizing combustion efficiency and reducing fuel consumption in commercial and industrial boiler applications.

Features

• Direct-coupled, modulating motor for smooth and precise control of dampers or valves.
• Keypad programmable interface allowing for easy local manual positioning and configuration.
• LED display with membrane keys for real-time monitoring of position and direction of travel.
• Multiple control inputs including 4-20mA, 0-10Vdc, and digital switch inputs (High/Low fire).
• Solid-state electronics housed in a robust NEMA 4 rated construction for durability in demanding environments.
• Two auxiliary contacts included for reliable position feedback to the flame safeguard system.
• Selectable rotation direction (clockwise or counter-clockwise) to suit various linkage configurations.

Applications

The Fireye AC6B1BD is primarily utilized in industrial and commercial combustion systems, including steam boilers, water heaters, and furnaces. It is designed to interface with electronic flame safeguard controls, such as Fireye BurnerLogix or Nexus systems, to accurately position fuel valves and air dampers. Its 75-degree fixed stroke makes it an ideal drop-in replacement for mechanical linkages requiring specific angular travel to maintain optimal thermal efficiency and safety standards.
