AC6A4CD Fireye Actuator

Overview

The Fireye AC6A4CD is a keypad-programmable, direct-coupled rotary actuator designed for use in burner and valve control systems. This modulating motor is typically paired with electronic controls to regulate process temperatures by adjusting the position of a butterfly valve. The unit features a unique display keypad that provides local manual control and visual indication of the drive shaft’s position and travel direction.

Features

• Keypad programmable for easy setup and local manual positioning control.
• Integrated LED display with membrane keys for status indication and parameter adjustment.
• Supports multiple positioning inputs, including 4-20mA, 0-10Vdc, and digital switch inputs.
• Two auxiliary contacts provided for precise position feedback to external systems.
• Selectable rotation direction (clockwise or counterclockwise) to match valve requirements.
• NEMA 4 rated construction ensures durability and protection in industrial environments.
