AC6A4BD Fireye Actuator

Overview

The Fireye AC6A4BD is a keypad programmable, direct-coupled, modulating rotary actuator designed for use in burner and valve control systems. It typically functions as a modulating motor that connects to a butterfly valve stem to regulate process temperatures. This model features a specific 270-degree (Left-Hand) keypad orientation for horizontal mounting with wiring connections on the left, providing an integrated interface for local manual control and parameter adjustments.

Features

• Direct-coupled, modulating motor for precise valve and damper control.
• Keypad programmable with an LED display and membrane keys for easy setup and status monitoring.
• Solid-state electronics for enhanced reliability and performance.
• Supports multiple input types for positioning, including 4-20mA, 0-10Vdc, and switch inputs.
• Two auxiliary contacts included for position feedback.
• Selectable clockwise or counterclockwise rotation to match system requirements.
• NEMA 4 rated construction for protection against environmental factors.
