AC6A2CA Fireye Actuator

Overview

The Fireye AC6A2CA is a keypad-programmable, direct-coupled rotary actuator designed for precise modulating control of dampers and butterfly valves in industrial burner systems. Operating on 120VAC, this AC Series motor serves as a high-performance replacement for legacy models, such as the Eclipse PRA. It features an inverted mounting configuration, meaning the wiring connections are located at the top of the unit, allowing for flexible installation in tight or non-standard burner environments. By eliminating linkage slop through a direct connection to the valve stem, it ensures accurate air-to-fuel ratio control to optimize combustion efficiency.

Features

• Solid-state electronics for reliable, maintenance-free operation.
• Integrated keypad and LED display for easy on-site programming and manual position control.
• Multiple control inputs including 4-20mA, 0-10Vdc, and digital switch inputs for positioning.
• Two auxiliary contacts providing position feedback for system monitoring.
• NEMA 4 rated construction for protection against harsh industrial environments.
• Selectable clockwise or counterclockwise rotation to suit specific installation needs.
• Keypad-adjustable minimum and maximum travel positions.

Applications

The AC6A2CA is primarily used in industrial and commercial combustion systems to regulate process temperatures by controlling air and gas flow. It is typically mounted directly onto butterfly valves or air dampers. Common applications include burner management systems (BMS), PID temperature control loops, and boiler room retrofits where a precise, modulating motor is required to maintain peak thermal efficiency. Its inverted design is specifically suited for installations where vertical space is constrained or where wiring must originate from above the mounting point.
