It accepts 1 to 5 V and -10 to +10 V input signals, with a 10 ms data update period. The module supports dual-redundant configuration and uses the \/A4S10 option for an analog pressure clamp terminal block with surge absorber.\u003c\/p\u003e\n\u003ch3\u003eInput Channels and Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe AAV144 receives voltage signals from field instruments and converts them into input data for the control system. All 16 channels are isolated from the system side. However, the available specifications do not establish isolation between individual input channels.\u003c\/p\u003e\n\u003cp\u003eThe module supports two input ranges:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 to 5 V DC\u003c\/li\u003e\n\u003cli\u003e-10 to +10 V DC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe input range can be selected collectively for CH1 to CH16. Individual channel range selection is not specified. The allowable input voltage is +\/-30 V, which should be distinguished from the normal measurement ranges.\u003c\/p\u003e\n\u003ch3\u003eAccuracy and Electrical Isolation\u003c\/h3\u003e\n\u003cp\u003eThe specified accuracy is +\/-4 mV for the 1 to 5 V range and +\/-20 mV for the -10 to +10 V range. Input resistance is 1 MOhm when the module is powered on and 200 kOhm when powered off.\u003c\/p\u003e\n\u003cp\u003eInput-to-system isolation withstands 1500 V AC for one minute under the specified test conditions. This isolation rating is relevant when checking electrical separation between field signal circuits and the control system. The rating should not be interpreted as a continuous operating voltage.\u003c\/p\u003e\n\u003ch3\u003eTerminal Block and Ordering Configuration\u003c\/h3\u003e\n\u003cp\u003eThe \/A4S10 option identifies a pressure clamp terminal block for analog signals with a surge absorber, model ATA4S-10. This distinguishes the configuration from \/A4S00, which uses the ATA4S-00 terminal block without the specified surge absorber option.\u003c\/p\u003e\n\u003cp\u003eThe terminal connection options documented for the AAV144 include pressure clamp terminals, MIL connector cables and the dedicated KS1 cable. The selected connection method matters when checking the applicable isolation withstand voltage.\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\u003eAAV144\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFull Model\u003c\/td\u003e\n\u003ctd\u003eAAV144-S50\/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\u003eIsolated Voltage 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 Signal\u003c\/td\u003e\n\u003ctd\u003e1 to 5 V DC, -10 to +10 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Isolation\u003c\/td\u003e\n\u003ctd\u003eIsolated between input and system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllowable Input Voltage\u003c\/td\u003e\n\u003ctd\u003e+\/-30 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Withstand Voltage\u003c\/td\u003e\n\u003ctd\u003e1500 V AC for 1 minute\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Power ON)\u003c\/td\u003e\n\u003ctd\u003e1 MOhm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Power OFF)\u003c\/td\u003e\n\u003ctd\u003e200 kOhm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy (1 to 5 V)\u003c\/td\u003e\n\u003ctd\u003e+\/-4 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy (-10 to +10 V)\u003c\/td\u003e\n\u003ctd\u003e+\/-20 mV\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 (1 to 5 V)\u003c\/td\u003e\n\u003ctd\u003e+\/-4 mV\/10 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Drift (-10 to +10 V)\u003c\/td\u003e\n\u003ctd\u003e+\/-20 mV\/10 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current Consumption\u003c\/td\u003e\n\u003ctd\u003e500 mA at 5 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Connection\u003c\/td\u003e\n\u003ctd\u003ePressure clamp terminal, MIL connector cable, dedicated KS1 cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Block Option\u003c\/td\u003e\n\u003ctd\u003eATA4S-10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.20 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e130 x 32.8 x 107.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eModel and Suffix Identification\u003c\/h3\u003e\n\u003cp\u003eThe ordering code identifies the module type and its hardware 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\u003eAAV144\u003c\/td\u003e\n\u003ctd\u003e16-channel isolated analog voltage input module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e-S\u003c\/td\u003e\n\u003ctd\u003eStandard type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003ctd\u003eNo explosion protection\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\/A4S10\u003c\/td\u003e\n\u003ctd\u003eAnalog pressure clamp terminal block with surge absorber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eATA4S-10\u003c\/td\u003e\n\u003ctd\u003eTerminal block model associated with \/A4S10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eThe \/A4S10 option is different from \/A4S00, which specifies the ATA4S-00 terminal block without the surge absorber option.
