It supports HART digital communication and uses the \/A4S00 option, which specifies a pressure-clamp terminal block (ATA4S-00) for field signal connections. The module converts control-system output values into analog current signals for connected instruments and control equipment.\u003c\/p\u003e\n\u003ch3\u003eOutput Function and Signal Configuration\u003c\/h3\u003e\n\u003cp\u003eThe AAI543 provides 16 analog output channels with a 4-20 mA DC signal range. Each channel supplies a current output corresponding to the control-system command, allowing the module to interface with devices such as control valve positioners and other current-operated field equipment.\u003c\/p\u003e\n\u003cp\u003eThe isolated-channel configuration separates the output circuits from the system side. This helps limit the propagation of electrical disturbances between field wiring and the control-system electronics. HART communication adds digital data exchange over the analog current loop, where supported by the connected field instrument and system configuration.\u003c\/p\u003e\n\u003ch3\u003eTerminal Block and Field Wiring\u003c\/h3\u003e\n\u003cp\u003eThe \/A4S00 option identifies the pressure-clamp terminal block ATA4S-00. This provides the physical termination interface for analog field wiring, rather than a separate output signal type. The terminal configuration should be checked against the installed module and cabinet wiring arrangement when replacing an existing unit.\u003c\/p\u003e\n\u003ch3\u003eOutput Performance and Load Requirements\u003c\/h3\u003e\n\u003cp\u003eThe published AAI543 hardware specifications provide an allowable load resistance of 0 to 750 ohms, an output accuracy of +\/-48 uA, and a data update period of 10 ms. These values are relevant when checking the connected actuator or positioner's input impedance and the response requirements of the control loop.\u003c\/p\u003e\n\u003ch3\u003eDual-Redundant Operation\u003c\/h3\u003e\n\u003cp\u003eThe H00 configuration specifies the standard switch-over response for redundant operation. When two identical AAI543 modules are configured as a redundant pair, the maximum period during which the field output falls below 4 mA during a control-to-standby switchover is 100 ms. This response characteristic should be considered when the connected field device has specific signal interruption requirements.\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\u003eAAI543-H00\/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 Output Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Output Channels\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Isolation\u003c\/td\u003e\n\u003ctd\u003eIsolated between output and system\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllowable Load Resistance\u003c\/td\u003e\n\u003ctd\u003e0 to 750 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit-Open Detection\u003c\/td\u003e\n\u003ctd\u003eLess than 0.65 mA\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\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\u003eHART Communication\u003c\/td\u003e\n\u003ctd\u003eAvailable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundant Operation\u003c\/td\u003e\n\u003ctd\u003eDual-redundant configuration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitch-over Response\u003c\/td\u003e\n\u003ctd\u003eStandard, maximum 100 ms below 4 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current Consumption\u003c\/td\u003e\n\u003ctd\u003e230 mA (5 V DC), 540 mA (24 V DC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eApprox. 0.40 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Block Option\u003c\/td\u003e\n\u003ctd\u003e\/A4S00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAssociated Terminal Block\u003c\/td\u003e\n\u003ctd\u003eATA4S-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eSuffix and Ordering Code Identification\u003c\/h3\u003e\n\u003cp\u003eThe ordering code identifies the communication function, redundancy response and terminal connection configuration:\u003c\/p\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eCode\u003c\/th\u003e\n\u003cth\u003eDescription\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAAI543\u003c\/td\u003e\n\u003ctd\u003e4-20 mA, 16-channel isolated analog output module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e-H\u003c\/td\u003e\n\u003ctd\u003eDigital communication with HART protocol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e0\u003c\/td\u003e\n\u003ctd\u003eStandard switch-over response in redundant configuration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e0\u003c\/td\u003e\n\u003ctd\u003eBasic type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\/A4S00\u003c\/td\u003e\n\u003ctd\u003ePressure Clamp Terminal Block\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eATA4S-00\u003c\/td\u003e\n\u003ctd\u003eAssociated terminal block model\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eThe H00 configuration is the standard-response basic type.
