This module provides 8 high-reliability output points with 12-bit resolution, specifically engineered to drive final control elements such as valves and actuators via a standard 4-20 mA current loop. Its TMR architecture ensures continuous process operation even in the event of a single component failure, making it a critical asset in safety-instrumented systems (SIS) within refineries, offshore oil platforms, and power generation facilities.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTMR Architecture:\u003c\/strong\u003e Utilizes triple modular redundancy with hardware voting to ensure high availability and fault tolerance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRapid Switching:\u003c\/strong\u003e Executes a transition to functional legs in less than 10 ms upon detection of a leg failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC-Coupled Design:\u003c\/strong\u003e Eliminates the need for bulky output transformers while simplifying field wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver-range Protection:\u003c\/strong\u003e Integrated protection rated at +42.5 VDC to mitigate damage from field-side voltage spikes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Resolution:\u003c\/strong\u003e 12-bit output resolution for precise control of field devices.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThe 3805E is intended for high-availability safety-critical environments, including:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEmergency Shutdown Systems (ESD)\u003c\/li\u003e\n\u003cli\u003eBurner Management Systems (BMS)\u003c\/li\u003e\n\u003cli\u003eCritical Process Control loops in petrochemical and nuclear industries\u003c\/li\u003e\n\u003cli\u003eTurbine control and monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e3805E\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eTMR Enhanced Analog Output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e8 Points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e12 Bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Range\u003c\/td\u003e\n\u003ctd\u003e4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitch Time (Leg Failure)\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 10 ms (Typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOver-range Protection\u003c\/td\u003e\n\u003ctd\u003e+42.5 VDC (Continuous)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to 85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoupling\u003c\/td\u003e\n\u003ctd\u003eDC Coupled, commoned return\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eESD Precautions:\u003c\/strong\u003e Always use a grounded wrist strap when handling the module to prevent electrostatic discharge damage to internal components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Down:\u003c\/strong\u003e Ensure the Tricon chassis power is disconnected or the slot is powered down before inserting or removing the module.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeating:\u003c\/strong\u003e Ensure the module is fully seated and the locking levers are engaged to guarantee proper backplane connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring:\u003c\/strong\u003e Use shielded twisted-pair cabling for 4-20 mA loops to minimize EMI\/RFI interference.
