ABB AI845 3BSE023675R1 Analog Input Module

AI845 babban aiki ne, ingantaccen ingantaccen tsarin shigar da analog a cikin ABB Compact Product Suite, wanda aka tsara don siyan siginar analog da sarrafawa a cikin tsarin sarrafa sarrafa kansa na masana'antu. An saita wannan ƙirar don aikace-aikacen guda ɗaya ko na yau da kullun kuma yana fasalta tashoshi na shigarwar analog masu zaman kansu na 8, suna tallafawa duka na yanzu (0 ... 20 mA, 4 ... 20 mA) da nau'in sigina (0 ... 5 V, 1 ... 5 V), samar da masu amfani da siginar siginar mai sassauƙa.

Tsarin AI845 ya haɗu da ayyukan bincike na ci gaba, tallafin sadarwa na HART, da ƙarfin jujjuya siginar madaidaici, yana sa ya dace da yanayin masana'antu daban-daban kamar sarrafa tsari, masana'antu, da sarrafa makamashi. Ƙirar sa na yau da kullun, kyakkyawan dacewa, da ƙarfin hana tsangwama ya sa ya zama kyakkyawan zaɓi don gina ingantaccen tsarin sarrafa kansa.
