Woodward 5464-550 NetCon 2-Channel Integrating Actuator Driver

The Woodward 5464-550 is a 2-channel integrating actuator driver for NetCon 5000 digital control systems. It converts digital control commands into precise analog current outputs to drive electro-hydraulic servo valves and proportional actuators in turbine and engine governor applications.

Features & Benefits

1. Integrating Control: Maintains precise actuator position by integrating error signals over time—ideal for hydraulic servo systems.
2. Dual-Channel Design: Drives two independent actuators or redundant servo coils from a single module.
3. High-Current Output: ±40 mA drive capability suits most industrial servo valves.
4. Fault Detection: Built-in diagnostics monitor coil continuity and driver health.

Applications

• Steam turbine governor valve control
• Gas turbine fuel valve positioning
• Compressor anti-surge valve control
• Hydraulic actuator positioning systems

FAQ

Q: What is the difference between 5464-550 and 5464-551?
A: The 5464-550 is an integrating actuator driver (with position feedback integration). The 5464-551 is a 2-channel proportional actuator driver (direct current output without integration). Choose based on your actuator control requirements.

Q: Can 5464-550 drive single-coil servo valves?
A: The 5464-550 is optimized for dual-coil servo valves. For single-coil applications, consider the PGPL458 (8901-458) or verify compatibility with Woodward.

Installation Guide

1. Install 5464-550 into NetCon 5000 chassis slot.
2. Connect servo valve coils to output terminals (observe polarity for dual-coil valves).
3. Wire LVDT or position feedback signals to corresponding input terminals.
4. Configure integrating gain and deadband in Woodward control software.
5. Perform stroke test to verify full actuator travel and linearity.

Selection Tips

• Actuator Type: Confirm your servo valve requires integrating vs. proportional drive.
• Coil Impedance: Verify servo valve coil impedance is within the driver's rated load range.
• Feedback: Integrating drivers require position feedback (LVDT/RVDT) for closed-loop operation.
