This intelligent function module converts small millivolt-level sensor signals into high-resolution 16-bit signed binary values, allowing the host PLC system to perform accurate thermal profiling and process adjustments. Engineered for challenging industrial environments, the module features individual channel disconnection detection and robust transformer-based electrical isolation between channels, mitigating ground loop noise and improving measurement fidelity.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;
