NX20-1 Fireye SERVO Motor

Overview

The Fireye NX20-1 is a precision industrial servo motor designed for the actuation of fuel valves and air dampers in combustion systems. It is primarily used with industrial burners to ensure accurate mechanical positioning and reliable burner modulation. This model is engineered for high-torque applications and provides critical feedback to a master controller via an integrated potentiometer.

Features

• High-torque performance suitable for stable burner and damper positioning.
• Two internal microswitches with adjustable cams to define end travel limits.
• Integrated single-turn conductive plastic potentiometer for continuous rotary position feedback.
• Sealed enclosure with NEMA 4 and IP65 protection ratings, making it suitable for harsh industrial environments.
• 2-wire drive circuit design for straightforward integration into control systems.
• Capable of an extended rotation angle of up to 270 degrees.

Applications

The NX20-1 is predominantly used in industrial and commercial combustion applications where precise control of air and fuel is required. It is commonly applied to fuel valve linkages and air damper assemblies on industrial burners. This servo motor is designed for use with Fireye Nexus and other compatible flame safeguard and burner management systems that require a 120V actuator with positional feedback.
