FAQ

Q1: What is the Woodward 5464-643 module?

A1: It is a 48-channel discrete input module with optical isolation, designed for Woodward's MicroNet control systems.

Q2: How is the module installed in a chassis?

A2: It is inserted into card guides and secured with two screws; handles on the front panel allow for safe disengagement from connectors.

Q3: How are the input channels connected and organized?

A3: Channels 1–24 connect via J1 and channels 25–48 via J2, each linked to a 24Vdc FTM with sequentially labeled I/O points.

Q4: What should be checked if all 48 DI modules show Fault LEDs?

A4: Inspect the chassis CPU module for potential failure, as this may indicate a system-level issue.

Q5: Where is the Woodward 5464-643 manufactured?

A5: It is manufactured in the United States (USA).
