AC6B1CA Fireye Actuator

Overview

The Fireye AC6B1CA is a keypad-programmable, direct-coupled rotary actuator designed for use in industrial burner and valve control systems. Functioning as a modulating motor, it is typically employed with electronic controls to regulate process temperatures by adjusting the flow of air or fuel. This model is engineered to connect directly to a butterfly valve stem, rotating 90 degrees between minimum and maximum positions to provide precise combustion control.

Features

• Direct-coupled design eliminates the need for complex linkages between the motor and the valve.
• Keypad programmable interface allows for local manual positioning and easy adjustment of parameters.
• LED display with membrane keys provides clear indication of current position and direction of travel.
• Upright keypad orientation specifically designed for vertical mounting with wiring connections at the bottom.
• Selectable clockwise or counterclockwise rotation to suit various installation requirements.
• Solid-state electronics ensure reliable, long-term performance in demanding environments.
• Dual auxiliary contacts included for essential position feedback to the control system.
• NEMA 4 rated construction provides protection against dust and water ingress.

Applications

The AC6B1CA actuator is primarily used in commercial and industrial combustion systems to control butterfly valves for gas and air applications. It is frequently utilized as a direct replacement for Eclipse PRA series actuators. Its robust design makes it suitable for managing firing rates in boilers, furnaces, and ovens where precise modulation is required to maintain efficiency and safety. It is often integrated with Fireye burner management and combustion control systems to ensure optimal fuel-to-air ratios.
