Woodward 5466-348 NetCon SIO Module 3xRS-485

Woodward 5466-348 NetCon SIO Module for Digital Actuator Drivers

Product Introduction

The 5466-348 from Woodward is a specialized Serial Input/Output module. It belongs to the NetCon family within the 9900 Series. This module connects directly to EM or GS/LQ digital actuator drivers. Specifically, it uses RS-485 communication for high-speed data exchange. Additionally, it supports remote driver configuration and real-time status monitoring.

Technical Specifications

Port and Communication Features

The Woodward 5466-348 includes three independent RS-485 ports. Each port operates with its own rate group. The protocol uses a standard RS-485 UART interface. Baud rate reaches 417 kbaud for fast data transmission. Parity is set to none, with 8 data bits and 1 stop bit. Consequently, this module achieves low latency and high reliability.

Driver Update Rate

Every port allows one driver per 5-millisecond cycle. Therefore, critical parameters update rapidly for precise control. Each driver’s address switches must match the driver number in the GAP application. This ensures correct identification and communication.

Remote Capabilities

The 5466-348 enables remote monitoring of driver parameters. It also allows remote parameter configuration. Furthermore, the module detects driver communication faults automatically. Any driver with a comm fault is disabled immediately for safety.

Positioning Accuracy

This module lets drivers issue a fast and very accurate position command. The command uses 16-bit resolution with no noise interference. Thus, positioning is both smooth and precise.

Functional Modes

The Woodward 5466-348 supports three operational roles depending on system needs.

Full Control Mode

In this mode, the module sends position demand and configuration data to the driver. Simultaneously, it monitors driver status outputs. This provides complete closed-loop control.

Configuration and Monitoring Only

Here, the module configures the driver and monitors status outputs. However, it does not send a position demand. Instead, a 4-20 mA input or CAN bus interface generates the demand.

Monitoring Only

The 5466-348 can also monitor driver status outputs alone. It neither configures nor sends position commands. Under this setup, the driver position demand comes from a 4-20 mA input or CAN bus. Additionally, configuration input may come from RS-232 or CAN bus.

Mechanical and Environmental Parameters

The Woodward 5466-348 shares the rugged design of the 9900 Series. It operates in temperatures from -20°C to +70°C. Humidity tolerance is 5% to 95% non-condensing. The module resists vibration typical of turbine environments. Its compact form factor fits standard control cabinets. Gross weight is 2.9 kg, simplifying handling and mounting.

Installation Guidelines

First, mount the 5466-348 securely inside a control panel. Use M4 or M5 screws with proper grounding. Next, connect 24VDC power to the designated terminals. Verify polarity before energizing.

Then, wire each RS-485 port to its corresponding digital actuator driver. Use twisted-pair shielded cables for best noise immunity. Termination resistors (120 ohms) may be needed at line ends. After wiring, set each driver’s address switch to match the GAP application number. Finally, configure the baud rate and parity via Woodward’s configuration tool. The module will begin updating drivers every 5 ms.

Frequently Asked Questions (FAQ)

1. Can the 5466-348 work with non-Woodward actuators?
No, this module is specifically designed for Woodward EM and GS/LQ digital actuator drivers only.

2. What happens if a driver’s address does not match the GAP application?
The Woodward 5466-348 will not communicate with that driver. Correct all address switches before operation.

3. How do I know if a communication fault occurs?
The module detects the fault and disables the affected driver automatically. Status bits are available via the control system.

4. Can different ports run at different baud rates?
Yes, each of the three RS-485 ports can operate with its own rate group. This allows mixing driver types on one module.

5. Does the 5466-348 support hot-swapping of drivers?
No, always power down the module before connecting or disconnecting any driver wiring.
