WOODWARD 5464-414 Analog Input/Output Combination Module

This model is a very crucial general-purpose analog input/output module in the Woodward MicroNet and NetCon control systems.

1. Product Description

The Woodward 5464-414 is a standard analog I/O module. It is specifically designed for the MicroNet digital control system and is used for monitoring and controlling prime movers (such as gas turbines, steam turbines, and large engines).

This module, through its high-density channel design, can simultaneously handle multiple analog signals and serves as the core interface between the system and on-site sensors and actuators.

2. Technical Data Sheet

Model: 5464-414

Series: MicroNet / NetCon 500

Input Channels (Inputs): * Usually consist of 8 analog inputs.

Supports 4–20 mA current signal or 0–5 V / 0–10 V voltage signal.

Output Channels (Outputs): * Usually consists of 4 analog outputs.

Mainly used for 4-20 mA proportional control.

Accuracy: 0.1% of full scale (typical value).

Isolation: The module has current isolation between the channel and the bus, preventing external electromagnetic interference (EMI) from affecting the control system motherboard.

Operating Temperature: -40 °C to +70 °C.

Power Consumption: Approximately 5 – 10 W.
