Triple Modular Redundancy (TMR) 2oo3 Architecture
The 5466-318 is architected specifically for integration into a MicroNet TMR system, functioning as one of three redundant kernel power supply modules. In a TMR 2oo3 architecture, the module ensures continuous operation through fault-tolerant power distribution. The unit performs galvanic isolation between the primary 24 VDC MicroNet bus and the regulated internal 5 VDC rails, ensuring that a failure in a single power module does not propagate to the other two modules within the TMR cluster. Fail-safe state execution is maintained by the synchronization of the three modules, allowing for uninterrupted system power in the event of an individual module fault or input supply disturbance.
Frequently Asked Questions
Q: What is the procedure for removing the 5466-318 module from the MicroNet TMR chassis?
A: Before extraction, all associated kernel power supply modules within the TMR cluster must be removed to prevent electrical contention or backplane damage. Ensure the system is powered down and the modules are extracted in accordance with the specified hardware removal sequence.
Q: How is the power health status indicated on the front faceplate?
A: The front faceplate features a single status LED. When illuminated, this indicator provides visual confirmation of the internal Power Health supply status. If the LED is extinguished, the module is failing to provide the regulated 5 VDC output, signaling a potential internal fault.
Field Installation Guidelines
- Mounting: Insert the module into the first slot of the MicroNet TMR kernel section. Ensure the module is seated fully into the backplane connectors to establish electrical continuity.
- Environmental Constraints: Installation is limited to non-hazardous locations or Class I, Groups A, B, C, D, Division 2 locations. Verify the installation site environment meets these criteria to prevent operational errors.
- Power Cabling: Ensure the 24 VDC main power source is stable and within the +/- 10% tolerance range. Use appropriately rated wiring to support the 10 A current throughput.
- Validation: Monitor the front panel LED upon power-up. In a redundant configuration, all three modules must exhibit active status indicators to confirm healthy synchronization of the TMR power bus.
