Designed for deployment in hazardous industrial locations, this module acquires precise temperature measurements from resistance thermometers (RTD), thermocouples, resistance transmitters, and millivolt sources in Zone 1 and Zone 2 hazardous areas.\u003c\/p\u003e\n\u003cp\u003eAs an intrinsic safety (Ex i) interface, the AI950S mounts onto S900 I\/O backplanes or power-distribution modules, converting field-level thermal signals into digitized process data for transmission via PROFIBUS DP or Modbus protocols to the control system. The unit incorporates galvanic isolation between field circuits, internal bus, and power supply, ensuring signal integrity and protection against common-mode transient voltages.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFour independent, configurable channels for RTD, thermocouple, resistance, and voltage inputs\u003c\/li\u003e\n  \u003cli\u003eIntrinsically safe Ex i field circuits for direct connection of field sensors located in Zone 1 and Zone 2\u003c\/li\u003e\n  \u003cli\u003eSupports sensor types including Pt100, Pt200, Pt500, Pt1000, Ni100, and standard thermocouples (Types B, E, J, K, N, R, S, T)\u003c\/li\u003e\n  \u003cli\u003eInternal cold junction compensation (CJC) for high-accuracy thermocouple measurements\u003c\/li\u003e\n  \u003cli\u003eHot-swappable module design allowing replacement under power without system shutdown\u003c\/li\u003e\n  \u003cli\u003eComprehensive diagnostic monitoring including wire-break detection, short-circuit detection, and out-of-range alarms\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHazardous area temperature monitoring in chemical and petrochemical processing plants\u003c\/li\u003e\n  \u003cli\u003eReactor core and distillation column thermal profiling in oil and gas refineries\u003c\/li\u003e\n  \u003cli\u003eHigh-precision temperature acquisition for distributed control systems (DCS) via S900 remote I\/O racks\u003c\/li\u003e\n  \u003cli\u003eCritical temperature interlock and safety shutdown monitoring loops\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eABB\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Series\u003c\/td\u003e\n      \u003ctd\u003eABB S900 I\/O\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCatalog Number \/ Model\u003c\/td\u003e\n      \u003ctd\u003eAI950S \/ 3KDE175521L9500\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModule Type\u003c\/td\u003e\n      \u003ctd\u003eTemperature Input Module (TI4-Ex)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Channels\u003c\/td\u003e\n      \u003ctd\u003e4 channels\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSupported Sensor Types\u003c\/td\u003e\n      \u003ctd\u003eRTD (Pt100, Ni100), Thermocouples (B, E, J, K, N, R, S, T), Resistance (0 to 400 Ohm, 0 to 2000 Ohm), Voltage (-80 mV to +80 mV)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eExplosion Protection\u003c\/td\u003e\n      \u003ctd\u003eII 2(1) G Ex ib [ia Ga] IIC T4 \/ II 2(1) D ex ib [ia Da] IIIC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eGalvanic Isolation\u003c\/td\u003e\n      \u003ctd\u003eBetween channels and system \/ power supply\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMounting\u003c\/td\u003e\n      \u003ctd\u003eS900 I\/O backplane \/ terminal block\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of Origin\u003c\/td\u003e\n      \u003ctd\u003eGermany\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eConnections \/ Interfaces\u003c\/h3\u003e\n\u003cp\u003eThe AI950S module connects to field sensors via S900 Series terminal blocks (either screw-type or spring-clamp) designed for hazardous area separation.
