Over the full temperature range, expect within ±0.5°C.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is \"wire-break\" detection and how does it work?\u003c\/strong\u003e\u003cbr\u003eFor 4-20mA loops and 1-5V signals, the module can detect if the sensor wire is broken. It triggers a diagnostic alarm if the signal falls below a very low threshold (near 0 mA or V).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I change settings while the PLC is running?\u003c\/strong\u003e\u003cbr\u003eYes. This module supports \"Configuration in RUN\" (CiR). You can reparameterize channels, like changing a limit alarm value, without stopping your process.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need external components for thermocouple measurement?\u003c\/strong\u003e\u003cbr\u003eThe module has internal temperature compensation for the cold junction. For best accuracy, you can also connect an external RTD to a dedicated reference channel for more precise compensation.\u003c\/p\u003e\n\u003ch3\u003eWarranty \u0026amp; Global Shipping\u003c\/h3\u003e\n\u003cp\u003eThis module is covered by a comprehensive \u003cstrong style=\"color: #27ae60;\"\u003e12-month warranty\u003c\/strong\u003e.
