The Woodward 5466-318 MicroNet TMR Kernel PS Module is a crucial component in Triple Modular Redundant (TMR) control systems, forming part of Woodward’s high-integrity MicroNet TMR platform. This power supply (PS) module ensures consistent, isolated, and redundant power delivery to the control kernel in critical applications where failure is not an option.

The 5466-318 module supports the core of a TMR system by feeding power to one of the three voting CPUs in the control architecture. Built with advanced protective features, it provides high stability and filtering, protecting critical electronic components against electrical disturbances, overloads, or power anomalies.

This module is designed with industrial robustness and system integrity in mind, delivering unmatched reliability for turbine control, process safety systems, and other high-availability automation scenarios. Its fail-safe operation, compliance with global certifications, and simple integration make it a foundational element of dependable control system design.

Frequently Asked Questions (FAQ)

1. What is the main role of the 5466-318 module?

   It provides isolated and redundant power to one of the three kernel processors in a MicroNet TMR system.

2. Can the module operate independently?

   No, it is designed to operate as part of a TMR system and is not intended for standalone use.

3. What happens if one of the modules fails in a TMR setup?

   The remaining two modules continue operation through voting logic, maintaining uninterrupted control.

4. Is it hot-swappable?

   In most cases, yes—but replacement should be conducted per Woodward’s TMR maintenance procedures.

5. How is power redundancy achieved?

   Three kernel power supply modules work in parallel; if one fails, the others take over seamlessly.

6. Does it require a specific chassis for mounting?

   Yes, it must be installed in a Woodward MicroNet TMR rack designed to accommodate it.

7. What kind of protection does the module offer?

   Built-in protection includes short-circuit, thermal, and over-voltage safeguards.

8. Is this module suitable for non-TMR systems?

   No, it is designed specifically for use in MicroNet TMR triple-redundant configurations.

9. How do I know if the module is functioning properly?

   LEDs on the front panel indicate power status and fault conditions for easy diagnostics.

10. Is it supported in international installations?

    Yes, the module complies with CE, UL, CSA, and RoHS certifications for global use.
