Woodward 5464-334 8 Channel Analog Input Module 4-20mA

Product Overview

The Woodward 5464-334 is an isolated 4-20 mA analog input module with 8 channels, part of the 5400 Series for turbine control systems. Weighing 0.8 kg, it delivers accurate measurements with 3000 VDC isolation between channels to prevent interference.

Key Features

8 isolated 4-20 mA input channels with independent precision voltage references. Onboard microcontroller enables automatic calibration and temperature compensation. Built in fault detection with LED indication for I/O faults. Visible fuse accessible through plastic cover for easy replacement. Minimal CPU involvement with autonomous rate group scheduling.

Technical Specifications

Installation Guide

Install the Woodward 5464-334 (0.8 kg) in the 5400 Series rack. Connect 10 to 60 VDC power supply. Wire 4-20 mA field signals to each of the 8 channels. Observe polarity for proper signal reading. Ensure ambient temperature stays within -25°C to +70°C. Replace visible fuse only with identical type and size if blown.

Engineering Advantages

3000 VDC isolation eliminates ground loops and noise interference. Automatic calibration and temperature compensation ensure measurement accuracy across temperature variations. Onboard fault detection alerts operators to channel or converter failures. Smart module design reduces CPU workload for improved system performance. Compact 0.8 kg construction simplifies cabinet mounting.

Frequently Asked Questions

Q1: How many analog input channels does the 5464-334 provide?

A1: It provides 8 isolated 4-20 mA analog input channels.

Q2: What is the isolation rating between channels?

A2: The module offers 3000 VDC isolation protection between channels.

Q3: How does the module detect faults?

A3: Each channel has a precision voltage reference read once per minute. If readings fall outside thresholds, the microcontroller signals a fault and illuminates the LED.
