It handles analog signal acquisition and output transmission within a control system. Furthermore, the module supports HART communication in the corresponding digital communication configuration, with channel-level selection for 2-wire or 4-wire transmitters.\u003c\/p\u003e\n\u003ch3\u003eAnalog Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe module processes input and output signals independently. Input channels accept 4-20 mA signals and convert them into internal control data, while output channels convert control data into corresponding 4-20 mA signals. The 10 ms data update period supports cyclic signal processing. Meanwhile, the 100 ms input and 40 ms output step response times define the module's response to changes in analog signals.\u003c\/p\u003e\n\u003ch3\u003eTransmitter Configuration and HART Communication\u003c\/h3\u003e\n\u003cp\u003eEach input channel supports either a 2-wire or 4-wire transmitter, selected through a setting pin. The transmitter power supply provides at least 14.8 V at 20 mA. Furthermore, the output circuit detects an open circuit when the output current falls below 0.65 mA.\u003c\/p\u003e\n\u003cp\u003eThe -H suffix identifies the version with HART digital communication. The standard -S suffix identifies the standard type without the specified HART communication option. Therefore, the suffix must be checked when selecting the module for HART-enabled field instruments.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\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\u003eModel\u003c\/td\u003e\n\u003ctd\u003eAAI841\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAnalog I\/O Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of I\/O Channels\u003c\/td\u003e\n\u003ctd\u003e8-channel input \/ 8-channel output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eNon-isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllowable Input Current\u003c\/td\u003e\n\u003ctd\u003e25 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Power ON)\u003c\/td\u003e\n\u003ctd\u003e400 ohm at 20 mA to 1000 ohm at 4 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Power OFF)\u003c\/td\u003e\n\u003ctd\u003e500 kohm or larger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllowable Output Load Resistance\u003c\/td\u003e\n\u003ctd\u003e0-750 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Circuit-Open Detection\u003c\/td\u003e\n\u003ctd\u003eLess than 0.65 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/-16 uA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/-48 uA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Update Period\u003c\/td\u003e\n\u003ctd\u003e10 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Step Response Time\u003c\/td\u003e\n\u003ctd\u003e100 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Step Response Time\u003c\/td\u003e\n\u003ctd\u003e40 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Power Supply\u003c\/td\u003e\n\u003ctd\u003eAt least 14.8 V at 20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Configuration\u003c\/td\u003e\n\u003ctd\u003e2-wire or 4-wire, selectable per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Drift\u003c\/td\u003e\n\u003ctd\u003e+\/-0.1% per 10 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current Consumption\u003c\/td\u003e\n\u003ctd\u003e310 mA at 5 VDC; 500 mA at 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHART Communication\u003c\/td\u003e\n\u003ctd\u003eAvailable with -H suffix\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Connection\u003c\/td\u003e\n\u003ctd\u003ePressure clamp terminal or KS cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eApprox. 0.3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eOrdering Code and Configuration\u003c\/h3\u003e\n\u003cp\u003eThe AAI841 ordering code identifies the communication type, explosion protection status and environmental options.
