The Fireye FX04 and FX04-1 servo motors are precision actuators designed to accurately position
valves and dampers. The servomotor interprets Modbus commands from an external control and
uses a stepper motor to drive to the commanded position. A feedback potentiometer provides contin-
uous positional information that can be read and cross checked by the external control.
The FX04 series servo motor offers a maximum output torque of 3lb.ft/ 4Nm with a minimum travel
time of 30 seconds for 90 degrees of rotation. Maximum rotation angle of the drive shaft is 100
degrees.
The servo is designed to be applied for fuel valves and air damper control on industrial burners. It
can also be applied to drive any type of flow control valve or damper as long as the output torque is
suited to the application.
