Operational Logic and System Utility

The 5466-258 handles the strict timing requirements of power generation and mechanical drive systems.

  • Inputs: 48 discrete points for limit switches, pressure switches, and operator commands.

  • Outputs: 24 channels to drive relays or solenoid valves.

As a Simplex module, it provides a cost-effective non-redundant control path while maintaining high reliability and diagnostic coverage consistent with the Woodward MicroNet family.

Frequently Asked Questions

Q: What is the difference between the 5466-258 and a redundant TMR module?
A: The 5466-258 is Simplex, operating as a single I/O path. TMR modules use three redundant paths with voting logic for higher fault tolerance in mission-critical safety functions.

Q: Does the 5466-258 require a separate FTM (Field Terminal Module)?
A: Yes, it typically connects to a Woodward FTM via high-density molded cable for organized field wiring and additional circuit protection.
