It provides channel-isolated input circuits and supports HART communication for transmitter data access. The module includes transmitter power supply functionality, individually configurable 2-wire or 4-wire inputs, and a 40 ms data update frequency.\u003c\/p\u003e\n\u003ch3\u003eInput Channels and Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe SAI143-H53\/A4S00 accepts up to 16 analog current input channels, with module isolation between the input signals and the system. Its rated input range is 4 to 20 mA, while the permissible input range extends from 0 to 25 mA.\u003c\/p\u003e\n\u003cp\u003eThe input impedance during power-on is specified as 250 Ohm plus the input current value. During power-off, the minimum input impedance is 500 kOhm. These characteristics are relevant when checking transmitter loop loading and signal behavior during module power interruptions.\u003c\/p\u003e\n\u003ch3\u003eHART Communication and Transmitter Configuration\u003c\/h3\u003e\n\u003cp\u003eThe SAI143-H53 version supports HART communication, allowing compatible field transmitters to provide digital device information alongside the analog 4-20 mA process signal. This is useful for transmitter configuration and diagnostics without treating the module as a conventional digital input device.\u003c\/p\u003e\n\u003cp\u003eEach channel can be individually configured for 2-wire or 4-wire transmitter connections through setting pins. The transmitter power supply provides at least 16.15 V at 20 mA and a maximum of 26.4 V at 0 mA, with an output current limit of 25 mA.\u003c\/p\u003e\n\u003ch3\u003eAccuracy and Electrical Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe specified rated accuracy for the SAI143-H version is +\/-16 uA over an input range of 0.05 to 23 mA. Its temperature drift is +\/-16 uA per 10 deg C, and the data update frequency is 40 ms.\u003c\/p\u003e\n\u003cp\u003eThe input signal circuit has a withstand voltage of 1.5 kV AC between the input signal and the system for one minute. Maximum current consumption is 320 mA from the 5 V system supply and 550 mA from the 24 V system supply.\u003c\/p\u003e\n\u003ch3\u003eTerminal Connection and Model Configuration\u003c\/h3\u003e\n\u003cp\u003eThe \/A4S00 option specifies the analog pressure clamp terminal block, identified by Yokogawa as STA4S-00.
