This half-height module is configured with dual low-voltage DC inputs to accept power from independent sources, minimizing the risk of a single-point failure in high-availability industrial monitoring setups. By utilizing high-frequency filtering and precise voltage regulation, it safeguards sensitive internal measurement cards from external electrical transients and voltage drops common in heavy industrial facilities.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #1a365d;
