Description
The Woodward 5464-544 is a 4-channel Actuator Control Module. Its main function is to drive and regulate various mechanical actuators, converting weak control signals from the control system into power signals that can drive valves, servo mechanisms, or other positioning devices.
Applications
Thermal power plant: Used in turbine DEH systems, driving main steam and governor valve coils via high-power channels.
Heavy chemical plant: Installed in compressor racks, using VME bus for precise gas valve control.
Shipbuilding industry: Used for marine diesel engine governor actuator control, with rugged plug-in design for vibration resistance.
Steel industry: Applied in blast furnace and TRT systems, driving hydraulic valves with compact multi-channel layout to save space.
Installation, Maintenance, and Hazard Prevention
Strict preheating: High-power drive boards require at least 4 hours preheating before operation to stabilize impedance. Skipping may cause thermal shock and damage the power stage.
No hot-swapping: The 5464-544 controls turbine fuel and steam valves. Power must be fully cut before replacement. Hot-plugging may cause arcing and unsafe full-valve opening or protection failure.
ESD and fault LED: Use anti-static wrist straps and touch only board edges. A red LED indicates internal self-test failure; the unit must be shut down and replaced immediately.
FAQ
Q: How many actuator control channels does the 5464-544 support?
A: Supports 4-channel actuator control.
Q: What is the output signal range of the 5464-544?
A: Output signal range is 0–200 mA.
Q: What DC supply voltage range is allowed for the 5464-544?
A: Allowed voltage range is 18–32 V DC (nominal 24 V DC).
Q: What is the control accuracy of the 5464-544 at 25 °C?
A: Accuracy is ±0.1% FSR.
Q: What is the module’s own power consumption current at 24 V for the 5464-544?
A: Self-consumption current is 60 mA.
