It provides isolated signal interfacing between field devices and the control system. The \/SA3S0 option specifies a pressure-clamp terminal connection using the ATSA3S-0 terminal model.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe ASI133-S00 belongs to Yokogawa's analog I\/O modules with built-in barriers. It receives 4-20 mA signals from field transmitters and makes the measured values available to the control system through its input channels.\u003c\/p\u003e\n\u003cp\u003eThe built-in barrier provides electrical isolation between the field interface and the system side. This arrangement supports the connection of field instrumentation where barrier-based signal interfacing is required. The module provides eight input channels.\u003c\/p\u003e\n\u003ch3\u003eInput Specifications and Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe module accepts a nominal input range of 4 to 20 mA, with an allowable input current of 22.5 mA. Its 100 ms step response time and 10 ms data update period define two different performance characteristics: the response time describes the input's reaction to a signal change, while the update period indicates how frequently updated data is made available.\u003c\/p\u003e\n\u003cp\u003eThe module supports both 2-wire and 4-wire transmitters. Their input resistance differs, so transmitter type and loop characteristics should be checked when planning field connections.\u003c\/p\u003e\n\u003ch3\u003eBuilt-In Barrier and Electrical Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe built-in barrier uses an isolated interface between the field circuit and the control system. However, the module does not provide galvanic isolation between individual input channels. This distinction is important when checking grounding arrangements and intrinsically safe field circuit design.\u003c\/p\u003e\n\u003cp\u003eFor intrinsically safe applications, the field wiring must comply with the applicable certification conditions and entity parameters. Yokogawa also specifies that a short circuit occurring on two or more field channels causes the intrinsic safety function of all module channels to fail.\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\u003eASI133-S00\/SA3S0\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 with Built-In Barrier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Input Channels\u003c\/td\u003e\n\u003ctd\u003e8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllowable Input Current\u003c\/td\u003e\n\u003ctd\u003e22.5 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (2-wire, Power ON)\u003c\/td\u003e\n\u003ctd\u003e400-750 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (4-wire, Power ON)\u003c\/td\u003e\n\u003ctd\u003e485-925 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Power OFF)\u003c\/td\u003e\n\u003ctd\u003e1 Mohm or higher\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\u003eStep Response Time\u003c\/td\u003e\n\u003ctd\u003e100 ms\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 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Power Supply\u003c\/td\u003e\n\u003ctd\u003e16 VDC or higher\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Supply Current Limit\u003c\/td\u003e\n\u003ctd\u003e20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Normal Mode Input Voltage (4-wire transmitter)\u003c\/td\u003e\n\u003ctd\u003e25 V\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\u003eMaximum Current Consumption\u003c\/td\u003e\n\u003ctd\u003e150 mA (5 VDC), 450 mA (24 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBarrier Type\u003c\/td\u003e\n\u003ctd\u003eIsolated interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Connection\u003c\/td\u003e\n\u003ctd\u003ePressure-clamp terminal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Model\u003c\/td\u003e\n\u003ctd\u003eATSA3S-0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmbient Temperature\u003c\/td\u003e\n\u003ctd\u003e-20 to 70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eISA Environmental Classification\u003c\/td\u003e\n\u003ctd\u003eISA S71.04 Class G3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eModel and Terminal Configuration\u003c\/h3\u003e\n\u003cp\u003eThe complete ordering designation identifies the analog input module and its field termination arrangement:\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\u003eASI133\u003c\/td\u003e\n\u003ctd\u003eAnalog input module with built-in barrier\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\u003e00\u003c\/td\u003e\n\u003ctd\u003eTwo fixed zero codes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\/SA3S0\u003c\/td\u003e\n\u003ctd\u003ePressure-clamp terminal option\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eATSA3S-0\u003c\/td\u003e\n\u003ctd\u003eAssociated terminal model\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eThe \/SA3S0 option identifies the standard pressure-clamp terminal arrangement.
