It supports HART digital communication in addition to analog signal acquisition. The \/A4S00 option specifies a pressure clamp terminal block (ATA4S-00), providing the field wiring interface for the module.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe AAI143-H50 converts field current signals into digital process data for use by the control system. Its 16 input channels are electrically isolated, helping separate field signal circuits from the system side and reducing the effects of electrical interference between connected measurement loops.\u003c\/p\u003e\n\u003cp\u003eThe HART-enabled configuration supports access to digital field-device information alongside the conventional 4-20 mA measurement. This allows compatible field instruments to provide additional variables through HART communication, subject to the control system's HART communication package and firmware requirements.\u003c\/p\u003e\n\u003ch3\u003eInput and Transmitter Characteristics\u003c\/h3\u003e\n\u003cp\u003eEach channel accepts a 4-20 mA DC signal, with an allowable input current of 24 mA. The module supports both 2-wire and 4-wire transmitters, selected individually for each channel using the module setting pins.\u003c\/p\u003e\n\u003cp\u003eFor 2-wire transmitters, the module provides a loop supply of at least 19.0 V at 20 mA, with a maximum of 25.5 V at 0 mA and a 25 mA output current limit. External wiring voltage drop must be considered when checking the transmitter's minimum operating voltage.\u003c\/p\u003e\n\u003ch3\u003eHART Communication\u003c\/h3\u003e\n\u003cp\u003eThe -H suffix identifies the HART digital communication version. HART communication allows compatible field instruments to exchange digital device information over the same 4-20 mA signal loop used for process measurement.\u003c\/p\u003e\n\u003cp\u003eWhen installed in an ER bus node unit with HART functionality, the EB401 firmware must be Revision 2 or later. The availability of HART data also depends on the installed system communication configuration.\u003c\/p\u003e\n\u003ch3\u003eTerminal Block and Redundancy\u003c\/h3\u003e\n\u003cp\u003eThe \/A4S00 option specifies the ATA4S-00 pressure clamp terminal block for field signal wiring. This is different from \/A4S10, which specifies a pressure clamp terminal block with a surge absorber.\u003c\/p\u003e\n\u003cp\u003eThe AAI143 supports dual-redundant configuration. Redundancy requires an appropriate system arrangement and compatible module configuration; the presence of a single AAI143-H50\/A4S00 does not itself provide redundancy.\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\/A4S00\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\u003eBase Model\u003c\/td\u003e\n\u003ctd\u003eAAI143\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Input Channels\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Isolation\u003c\/td\u003e\n\u003ctd\u003eIsolated\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 ohm (at 20 mA) to 350 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\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\u003eWithstanding Voltage\u003c\/td\u003e\n\u003ctd\u003e1500 V AC for 1 minute (input to system, subject to cable conditions)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Power Supply\u003c\/td\u003e\n\u003ctd\u003e19.0 V or higher at 20 mA;
