This hardware solution integrates both input and output functionalities into a single card, offering 8 channels for analog signal acquisition and 8 channels for analog control output. Featuring the \"H\" designation for HART digital communication, it enables seamless bidirectional data exchange with smart field instruments. The inclusion of the \/K4A00 option provides a factory-fitted KS Cable Interface Adapter (Model ATK4A-00), significantly simplifying the interconnectivity between the I\/O node and the terminal field wiring. This dual-purpose module is ideal for applications where space optimization within the FIO node is a priority without sacrificing high-precision control.\u003c\/p\u003e\n\u003ch3\u003eTechnical Infrastructure and Hardware Logic\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eI\/O Configuration:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e8 Analog Inputs \/ 8 Analog Outputs (Non-isolated)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInput Signal Capability:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e4 to 20 mA or 1 to 5 V DC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Signal Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e4 to 20 mA DC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDigital Communication:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHART Protocol Support (Versions 5\/6\/7)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSampling Rate:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e10 ms data update period\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMeasurement Accuracy:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eInput ±16 µA; Output ±48 µA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eTransmitter Power:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e14.8 V minimum (at 20 mA) to 26.4 V maximum\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInterface Hardware:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrated KS Cable Adapter (ATK4A-00)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCurrent Consumption:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e450 mA at 24 V DC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMass:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.3 kg (Approx. 300g)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical Footprint:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e130 mm (H) x 32.8 mm (W) x 107.5 mm (D)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003ePerformance Limit\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eAllowable Input Current\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e25 mA\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eOutput Resistance\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eSuitable for 4-20 mA loop loads\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eIsolation Strength\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e500 V AC (Field-to-System)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eEnvironment Rating\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eStandard industrial use (Basic type)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFunctional Deployment and Process Utilities\u003c\/h3\u003e\n\u003cp\u003eThe AAI841-H50\/K4A00 is frequently deployed in localized control loops where both sensing and actuation are managed within the same geographic area of a plant.
