The Woodward 5464-551, also cataloged as the 5464-551 Actuator Driver Module, operates as a dedicated hardware component for closed-loop actuator positioning and signal integration within NetCon 5000 platforms.

Hardware Specifications

Actuator Loop Feedback Response and Real-Time Processing

Driven by an onboard 32-bit microcontroller, the 5464-551 card executes real-time data processing to optimize actuator loop feedback response in high-speed turbine regulation loops. The hardware combines 6 analog inputs (4-20 mA), 4 analog outputs (4-20 mA), 12 isolated digital inputs, and 8 relay outputs on a single rack-mounted board. Internal board layouts are engineered for efficient thermal heat sink dissipation profiles, maintaining stable current regulation and signal acquisition across the extended operating temperature envelope of -40 deg C to +85 deg C.

Frequently Asked Questions

Q: What communication protocols and physical interfaces are supported on the 5464-551?

A: The card integrates Ethernet, RS-485, and RS-232 serial interfaces, providing native support for Modbus RTU and Modbus TCP/IP protocols.

Q: What is the operating voltage window for the primary power supply?

A: The module operates across an input power supply range of 18-36 VDC.

Q: How are the digital input signals isolated from system noise?

A: All 12 digital input channels feature discrete galvanic isolation to prevent common-mode field noise from affecting controller processing logic.

Field Installation Guidelines

• Verify that rack backplane power and external 18-36 VDC supply lines are fully de-energized before sliding the module into its chassis slot.
• Utilize shielded twisted-pair cabling for all 4-20 mA analog I/O loops and serial communication runs (RS-485/RS-232).
• Terminate all cable shields to a designated chassis earth ground bar using low-impedance clamps to ensure EMC compliance.
• Confirm proper rack mounting retention screw torque to preserve physical frame alignment and earth ground continuity.
