This slot-mounted hardware card provides direct physical\/electrical execution by routing 16 independent analog current loops through a single grouped galvanic isolation stage, converting raw 0-20 mA or 4-20 mA field signals into 12-bit digital values without timing synchronization drift.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\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\u003eAI625\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eSweden (SE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.225 kg (Net Weight)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e252 mm x 273 mm x 40 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003eStandard industrial cabinet baseline range\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eEvaluated by subrack backplane current draw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eI-O_Module (Analog Input)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Input Channels\u003c\/td\u003e\n\u003ctd\u003e16 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog-to-Digital Resolution\u003c\/td\u003e\n\u003ctd\u003e12 bits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Configuration\u003c\/td\u003e\n\u003ctd\u003e0-20 mA \/ 4-20 mA range profile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInternal Input Shunt Resistance\u003c\/td\u003e\n\u003ctd\u003e100 ohm internal shunt per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGroup Isolation Barrier\u003c\/td\u003e\n\u003ctd\u003eGalvanic isolated as one group\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Mode Voltage (CMV)\u003c\/td\u003e\n\u003ctd\u003e50 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Mode Rejection Ratio\u003c\/td\u003e\n\u003ctd\u003eCMRR \u0026gt; 100 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCustoms Tariff Code\u003c\/td\u003e\n\u003ctd\u003e85389091 (HS Code: 853890)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRegulatory Compliance Note\u003c\/td\u003e\n\u003ctd\u003eExempted from 2011\/65\/EU (RoHS) scope per Article 2(4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity and I\/O Density Scaling\u003c\/h3\u003e\n\u003cp\u003eThe AI625 coordinates with the S600 I\/O cluster to maintain baseline backplane bus communication velocity metrics, ensuring that high-density data updates are transferred to the central processor registers within fixed scan-cycle intervals. By routing 16 independent input channels through an internal 100 ohm shunt resistance array, the module handles multi-point physical I\/O density scaling routines smoothly without forcing inter-channel heat build-up or signal crosstalk. The front-end filtering network delivers a Common Mode Rejection Ratio (CMRR) greater than 100 dB against 50 V common mode voltage perturbations, maintaining complete firmware flash compatibility with upstream Advant Master controllers while streaming raw conversion metrics directly to the process tracking registers.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the single-group galvanic isolation design of the AI625 impact field wiring layouts?\u003c\/p\u003e\n\u003cp\u003eA: Because all 16 channels are isolated as one group, they share a common reference potential inside the module. Field wiring loops must be carefully managed to ensure that individual current loops do not introduce different ground potentials that exceed the 50 V Common Mode Voltage (CMV) threshold relative to that shared group reference.\u003c\/p\u003e\n\u003cp\u003eQ: Can the AI625 module measure voltage signals directly across its input terminals?\u003c\/p\u003e\n\u003cp\u003eA: No, the module incorporates fixed, internal 100 ohm shunt resistors designed to convert 0-20 mA and 4-20 mA current loops into internal voltage drops. Connecting direct voltage sources without external dropping resistors will bypass the intended conversion metrics and can damage the input conditioning channels.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":45054402887795,"sku":"AI625","price":233.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-05-25_09-55-34_bdb2114f-f375-456f-97aa-1f80f0325251.png?v=1780025946","url":"https:\/\/www.dcssupplier.com\/products\/abb-ai625-analog-input","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
