AC6B2CA Fireye Actuator

Overview

The Fireye AC6B2CA is a keypad-programmable, direct-coupled rotary actuator designed for use in industrial burner and valve control systems. This modulating motor is typically employed to regulate process temperatures by controlling the position of air dampers or butterfly valves. The AC6B2CA is a 230V model specifically configured for inverted (upside-down) mounting, featuring an integrated LED display and membrane keypad for local manual control and parameter programming.

Features

• Solid-state electronics for precise modulating control
• Keypad-programmable settings for minimum and maximum travel positions
• LED display with membrane keys for status indication and local manual positioning
• Flexible input compatibility accepting 4-20mA, 0-10Vdc, and digital switch signals
• Two auxiliary contacts included for position feedback to external systems
• Selectable rotation direction (clockwise or counter-clockwise)
• NEMA 4 construction for protection against environmental factors
• Direct-coupled design eliminates the need for complex linkages in many applications

Applications

The Fireye AC6B2CA is primarily used in commercial and industrial combustion systems to provide accurate positioning for fuel and air control. It is designed to interface with electronic controllers to manage air/gas dampers or butterfly valves in boiler rooms and process heating applications. The inverted mounting configuration is ideal for installations where space constraints or piping layouts require the actuator to be mounted upside-down with wiring accessed from the top. It serves as a reliable component for maintaining optimal fuel-air ratios to increase burner efficiency and reduce emissions.
