5464-643

Overview

5464-643 is a Woodward discrete input module with 48 optically isolated input channels.

Input & Signal

• Number of channels: 48

• Input type: Optically isolated discrete input

• Input current: 3 mA

• Data flow: Field switches and relays feed data; CPU accesses data via VME interface

Installation & Connection

• Mounting: Inserted into chassis card guides, secured by two screws and handles for easy removal

• Connectivity: Connected to two 24 V DC Discrete Input/Output FTMs via low-density discrete cables

• Channel mapping: Channels 1–24 on FTM J1; channels 25–48 on FTM J2, matching software locations

Diagnostics

• Fault indicator: Fault LEDs on all modules may indicate CPU failure in the chassis during normal operation
