FAQ

Q: What is the difference between 5464-551 and 5464-552?
A: The 5464-551 is a 2-channel proportional actuator driver. The 5464-552 is an ACT integrating driver (with integration function for position control). The 5464-551 is suitable for direct proportional control, while 5464-552 adds integrating capability for enhanced position accuracy.

Q: Can I use 5464-551 with Woodward 505 governor?
A: The 5464-551 is a NetCon 5000 module. For 505 governors, use dedicated 505 actuator driver modules or verify NetCon-505 compatibility.

Installation Guide

1. Install 5464-551 into NetCon 5000 chassis.
2. Connect servo valve coils to channel A and B output terminals.
3. Verify coil polarity for proper valve direction.
4. Set gain and offset trim pots per servo valve calibration requirements.
5. Perform valve stroke test and verify linearity across full range.

Selection Tips

• Control Mode: Choose 5464-551 for proportional control; 5464-550/552 for integrating control with position feedback.
• Valve Compatibility: Verify your servo valve coil specifications match the driver's output ratings.
