Signal Isolation\u003c\/h3\u003e\n\u003cp\u003eThe AAT141-S50 S2 integrates channel-to-system galvanic isolation rated for 1500 VAC to prevent ground loop noise from corrupting low-voltage millivolt signals. The hardware includes internal cold junction compensation (CJC) circuitry calibrated to deliver accurate reference offsets within +\/-1 deg C. Individual channels support independent software parameterization for thermocouple linearized curves (JIS\/IEC standard types J, K, E, B, R, S, T, N) or millivolt ranges (-100 to +150 mV and -20 to +80 mV), alongside a configurable 60-second sensor burnout detection routine.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the module handle a broken sensor wire on a thermocouple channel?\u003c\/p\u003e\n\u003cp\u003eA: The module executes a configurable burnout detection sequence.
