As a core component of Safety Instrumented Systems (SIS), this module features three independent input channels to perform high-accuracy signal acquisition from field sensors using Triple Modular Redundancy (TMR) architecture. The \u003cstrong\u003eTriconex 3703E\u003c\/strong\u003e supports 0-5 VDC or 0-10 VDC differential isolated signal inputs, which are software-configurable via TriStation 1131. Each channel provides independent signal conditioning and opto-isolation between the field and the system, effectively preventing a single-channel failure from affecting other channels. The module utilizes a built-in Mid-Value Selection algorithm to vote on the three sets of acquired data, ensuring the highest data integrity, functional safety, and continuous system availability in critical industrial protection applications.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUtilizes Triple Modular Redundancy (TMR) architecture with three completely independent input channels.\u003c\/li\u003e\n\u003cli\u003eSupports 16-point differential isolated analog inputs, providing up to 200V peak channel-to-channel isolation.\u003c\/li\u003e\n\u003cli\u003eInput voltage ranges are configurable via TriStation 1131 software for 0-5 VDC or 0-10 VDC (including a +6% overrange capability).\u003c\/li\u003e\n\u003cli\u003eFeatures comprehensive, continuous online self-diagnostics to monitor channel operational status in real time.\u003c\/li\u003e\n\u003cli\u003eSupports Hot-Spare functionality, allowing replacement of faulty modules while the system is online without interrupting the process.\u003c\/li\u003e\n\u003cli\u003eMechanically keyed design prevents incorrect insertion into the chassis slots.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEmergency Shutdown Systems (ESD)\u003c\/li\u003e\n\u003cli\u003eFire and Gas Detection Systems (F\u0026amp;G)\u003c\/li\u003e\n\u003cli\u003eBoiler and Burner Management Systems (BMS)\u003c\/li\u003e\n\u003cli\u003eHigh-reliability control for steam turbines and large rotating machinery\u003c\/li\u003e\n\u003cli\u003eSafety parameter monitoring in critical process industries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTriconex (Invensys)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3703E\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModule Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTMR, Analog Input (AI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNumber of Input Points\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e16, differential, isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIsolated Points\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0-5 VDC or 0-10 VDC (selected via TriStation 1131)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Update Rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eResolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12 bits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAccuracy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 0.15% of FSR, from 0 to 60 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Resistance (Load)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30 MΩ (DC) minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower-Off Resistance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30 MΩ (DC) minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCommon Mode Rejection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-90 dB @ 60Hz minimum, -100 dB @ DC minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCommon Mode Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e+200V peak\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLeg-to-Leg Isolation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20 kΩ typical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNormal Mode Rejection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-3 dB @ 8Hz, -17 dB @ 60Hz, -23 dB @ 120Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Overrange Protection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e150 VDC \/ 115 VAC continuous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.7 to 6.0 lbs.
