It is intended for acquiring analog process signals and converting them into digital values for controller processing, supporting stable measurement performance for closed-loop control, trending, and alarm functions in DCS applications.\u003c\/p\u003e\n\u003cp\u003eThis module is selected when a compact, rack-mounted analog acquisition solution is required for plant instrumentation such as transmitters, analyzers, and temperature elements (when used with the appropriate input type and wiring method). It is supplied as a replacement spare for installed systems and should be matched to the correct I\/O station\/controller family and revision.\u003c\/p\u003e\n\u003cp\u003eTechnical correction note\u003cbr\u003eThe header lists “Digital I\/O Module,” which conflicts with the part description and typical 07AI naming convention. This item is treated here as an analog input (AI) module. The source text also includes inconsistent weight values (0.36 kg vs 2.36 kg). The datasheet header weight (2.36 kg) is used below. “Ethernet router” is not applicable to this I\/O module.\u003c\/p\u003e\n\u003ch3\u003eSignal \u0026amp; Hardware Characteristics\u003c\/h3\u003e\n\u003ctable class=\"w-fit min-w-(--thread-content-width)\"\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel \/ Order Code\u003c\/td\u003e\n\u003ctd\u003e07AI91 \/ GJR5251600R0202\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\u003eSystem Family\u003c\/td\u003e\n\u003ctd\u003eAdvant OCS \/ 800xA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Context\u003c\/td\u003e\n\u003ctd\u003eDCS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eBrand New\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStatus\u003c\/td\u003e\n\u003ctd\u003eActive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eSweden\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAvailability\u003c\/td\u003e\n\u003ctd\u003eIn Stock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMOQ\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApprox.
