It supports HART digital communication, allowing the control system to acquire analog process measurements while accessing additional information from compatible smart field instruments. The associated ATK4A-00 S1 is a KS cable interface adapter used for the field connection arrangement.\u003c\/p\u003e\n\u003ch3\u003eInput Channels and Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe module provides 16 electrically isolated input channels for 4-20 mA DC process signals. Each channel can receive a signal from a 2-wire or 4-wire transmitter, with the transmitter type selected individually using the channel setting pin.\u003c\/p\u003e\n\u003cp\u003eThe module converts the incoming current signals into digital measurement values for the Field Control Station (FCS). Channel isolation separates the field input circuits from the system side, with a specified withstand voltage of 1500 V AC for one minute.\u003c\/p\u003e\n\u003ch3\u003eHART Communication\u003c\/h3\u003e\n\u003cp\u003eThe H50 configuration includes HART digital communication. In addition to the primary analog measurement, compatible HART instruments can provide digital device information through the same current loop.\u003c\/p\u003e\n\u003cp\u003eHART functionality has firmware requirements: module revision R3.02 or later is specified for HART support. When installed in a remote node, the EB401 firmware must be Rev. 2 or later.\u003c\/p\u003e\n\u003ch3\u003eTerminal Connection and Adapter\u003c\/h3\u003e\n\u003cp\u003eThe ATK4A-00 is identified as a KS cable interface adapter for connecting the AEA4D terminal board. It provides the interface between the module-side connection and the field wiring arrangement. The adapter should be checked as part of the complete I\/O connection configuration rather than treated as an additional analog input module.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure\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\u003eAAI143-H50 S1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAssociated Adapter\u003c\/td\u003e\n\u003ctd\u003eATK4A-00 S1\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 Input Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Input Channels\u003c\/td\u003e\n\u003ctd\u003e16, isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllowable Input Current\u003c\/td\u003e\n\u003ctd\u003e24 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Power ON)\u003c\/td\u003e\n\u003ctd\u003e270-350 ohm, depending on input current\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Power OFF)\u003c\/td\u003e\n\u003ctd\u003e500 kOhm or higher\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e+\/-16 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-to-System Withstand Voltage\u003c\/td\u003e\n\u003ctd\u003e1500 V AC, 1 minute\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e19.0 V or higher at 20 mA; 25.5 V or lower at 0 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Output Current Limit\u003c\/td\u003e\n\u003ctd\u003e25 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Drift\u003c\/td\u003e\n\u003ctd\u003e+\/-16 uA per 10 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current Consumption\u003c\/td\u003e\n\u003ctd\u003e230 mA at 5 V DC; 540 mA at 24 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the AAI143-H50 S1 support HART instruments?\u003c\/p\u003e\n\u003cp\u003eA: Yes.
