This specific model provides 16 channels for monitoring 4 to 20 mA current loops or 1 to 5 V DC voltage signals. Equipped with the \/K4A00 option, it includes a factory-integrated KS Cable Interface Adapter (ATK4A-00), streamlining the connection between the I\/O module and the terminal board. The \"H\" designation ensures full HART digital communication compatibility, allowing the DCS to retrieve multi-variable data and diagnostic information from smart field transmitters. This module is an essential component for high-point-count installations where efficient rack space utilization and advanced device management are required.\u003c\/p\u003e\n\u003ch3\u003eCritical Engineering Parameters\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInput Density:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e16 non-isolated channels\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSignal Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e4 to 20 mA DC or 1 to 5 V DC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDigital Protocol:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHART Communication supported (H50 suffix)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eConversion Precision:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e±16 µA for current; ±4 mV for voltage\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\u003eTransmitter Power Supply:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e14.8 V or higher at 20 mA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eModule Protection:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e500 V AC withstand voltage (Field-to-System)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePower Requirements:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e310 mA at 5 V DC; 450 mA at 24 V DC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eModule Weight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.2 kg (Net weight) \/ 3.0 kg (Shipping weight with adapter)\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\u003eOperational Variable\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification Value\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\u003eMax Input Current\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e27 mA\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eMax Input Voltage\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e±13 V\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eInput Resistance (ON)\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e400 Ω to 1000 Ω\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eInput Resistance (OFF)\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e500 kΩ or larger\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eInterface Adapter\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eATK4A-00 (KS Cable Type)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eIndustrial Sector Applications\u003c\/h3\u003e\n\u003cp\u003eThe AAI141-H50\/K4A00 is frequently utilized in large-scale processing facilities that demand high-density monitoring without the need for channel-to-channel isolation.
