This intrinsically safe module processes signals from various temperature sensors and transmits digitized process values to the control system via fieldbus communication. It is engineered for integration into modular remote I\/O stations, providing accurate thermal measurement and monitoring across demanding industrial process automation environments.\u003c\/p\u003e\n\u003cp\u003eBuilt for harsh industrial deployments, the AI950S module supports direct connection of thermocouples and resistance temperature detectors (RTDs), incorporating internal cold junction compensation and comprehensive sensor fault diagnostics. Its modular plug-in construction allows for rapid installation and hot-swapping on dedicated backplanes or terminal blocks within Zone 1 or Zone 2 hazardous locations, communicating upstream with distributed control systems (DCS).\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFour-channel temperature input configuration optimized for RTD and
