5464-334 Overview

The Woodward 5464-334 Analog Input is an isolated 8-channel analog input module designed for 4-20mA signals. It provides channel-to-channel isolation for accurate measurement and integrates an onboard microcontroller with diagnostic LED indication. This module is part of the 5400 Series used in turbine control systems.

Features and Benefits

• Independent Rate-Group Scheduling: Each I/O module autonomously manages its scheduling, minimizing CPU load.

• Onboard Diagnostics & Auto-Calibration: Built-in microcontroller performs online fault detection and automatic temperature compensation.

• Real-Time Fault Monitoring: Detects anomalies per channel and signals faults for immediate system response.

• Fuse Protection with Visual Access: Each module includes a visibly accessible, user-replaceable fuse for circuit protection.

FAQ

Q1: What is the Woodward 5464-334?

A1: It is an isolated 8-channel analog input module designed for 4-20mA signals, used in turbine control systems.

Q2: What key feature ensures measurement accuracy?

A2: Each channel is electrically isolated and includes automatic temperature compensation and calibration.
