It provides module isolation, individual channel configuration for 2-wire or 4-wire transmitters, and an integrated transmitter power supply for 2-wire connections. The specified assembly includes a pressure clamp terminal block with a surge absorber.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe SAI143 converts field current signals into input data for the Yokogawa control system. Its 16 input channels support a rated range of 4 to 20 mA, with a permissible input range of 0 to 25 mA. The 40 ms data update frequency defines the interval at which updated input values are made available to the system.\u003c\/p\u003e\n\u003cp\u003eModule isolation separates the input signal circuits from the system side. The specified insulation withstand voltage is 1.5 kV AC for one minute between the input signal and system.\u003c\/p\u003e\n\u003ch3\u003eTransmitter Interface and Configuration\u003c\/h3\u003e\n\u003cp\u003eEach channel can be configured individually for 2-wire or 4-wire transmitter connections. The configuration is changed using setting pins, allowing different transmitter wiring arrangements to be handled within the same module.\u003c\/p\u003e\n\u003cp\u003eIn 2-wire mode, the module provides transmitter loop power. The specified supply voltage is at least 16.15 V at 20 mA and up to 26.4 V at 0 mA, with an output current limit of 25 mA. The transmitter power supply can be switched ON or OFF for all 16 channels simultaneously when the channels are configured for 2-wire operation.\u003c\/p\u003e\n\u003ch3\u003eInput Accuracy and Electrical Characteristics\u003c\/h3\u003e\n\u003cp\u003eFor the SAI143-S version with style code S3, the rated accuracy is ±16 uA over an input range of 0.05 to 23 mA. This accuracy specification is different from earlier style-code versions, which have a narrower specified accuracy range. Temperature drift is ±16 uA per 10 deg C.\u003c\/p\u003e\n\u003cp\u003eDuring power-on, the input impedance consists of a 250 ohm base value plus the voltage drop contribution of the internal input protection circuit. The maximum protection-circuit voltage drop is 0.45 V. The module input impedance varies with signal current, from approximately 272.5 ohm at 20 mA to 362.5 ohm at 4 mA. During power-off, the specified input impedance is at least 500 kOhm.\u003c\/p\u003e\n\u003ch3\u003eTerminal Connection and Surge Protection\u003c\/h3\u003e\n\u003cp\u003eThe \/A4S10 option specifies an analog pressure clamp terminal block with an integrated surge absorber, identified by Yokogawa as STA4S-10. This configuration provides the field wiring interface for the analog input signals.\u003c\/p\u003e\n\u003cp\u003eThe SAI143 supports pressure clamp terminals, MIL cable connections, and dedicated signal cables as external connection methods. The supplied \/A4S10 configuration specifically identifies the pressure clamp terminal block rather than a signal cable interface adapter.\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\u003eSAI143-S53\/A4S10\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Isolation\u003c\/td\u003e\n\u003ctd\u003eModule isolation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Input Range\u003c\/td\u003e\n\u003ctd\u003e4 to 20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePermissible Input Range\u003c\/td\u003e\n\u003ctd\u003e0 to 25 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance (Power-ON)\u003c\/td\u003e\n\u003ctd\u003e250 ohm + input protection circuit voltage drop contribution\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance (Power-OFF)\u003c\/td\u003e\n\u003ctd\u003e500 kOhm minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Accuracy\u003c\/td\u003e\n\u003ctd\u003e±16 uA (0.05 to 23 mA, style code S3 or later)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Update Frequency\u003c\/td\u003e\n\u003ctd\u003e40 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Drift\u003c\/td\u003e\n\u003ctd\u003e±16 uA\/10 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Power Supply\u003c\/td\u003e\n\u003ctd\u003e16.15 V minimum at 20 mA;
