Zotulutsa za Analogi

Module ya analogi yotulutsa (AO) imalandira zidziwitso zochokera ku gawo lalikulu la purosesa panjira iliyonse itatu. Deta iliyonse imavoteredwa ndipo njira yabwino imasankhidwa kuti iyendetse zotsatira zisanu ndi zitatuzi. Module imayang'anira zomwe zikuchitika (monga ma voliti olowera) ndikusunga ma voliyumu amkati kuti azitha kudziyesa okha komanso chidziwitso chaumoyo wa module.

Njira iliyonse yomwe ili pagawoli imakhala ndi chigawo cha loopback chomwe chimatsimikizira kulondola ndi kupezeka kwa zizindikiro za analogi mosasamala za kupezeka kwa katundu kapena kusankha njira. Mapangidwe a module amalepheretsa njira yosasankhidwa kuyendetsa chizindikiro cha analogi kupita kumunda. Kuphatikiza apo, kuwunika kosalekeza kumachitika panjira iliyonse ndi gawo la gawoli. Kulephera kwa matenda aliwonse kumalepheretsa wolakwayo

njira ndikuyambitsa Fault indicator, yomwe imayendetsa alamu ya chassis. Chizindikiro cha module Fault chimangowonetsa cholakwika cha njira, osati kulephera kwa module. Ma module akupitilizabe kugwira ntchito bwino pomwe ma tchanelo ambiri alephera. Kutsegula kwa loop kumaperekedwa ndi chizindikiro cha LOAD chomwe chimayambitsa ngati gawoli silingathe kuyendetsa panopa ku chimodzi kapena zingapo zotuluka.

Gawoli limapereka magwero amphamvu a loop owonjezera omwe ali ndi mphamvu yamunthu payekha ndi zizindikiro za fuse zotchedwa PWR1 ndi PWR2. Mphamvu zamagetsi zakunja zotulutsa analogi ziyenera kuperekedwa ndi wogwiritsa ntchito. Gawo lililonse la analogi limafuna 1 amp @ 24-42.5 volts. Chizindikiro cha LOAD chimagwira ntchito

ngati kuzungulira kotseguka kwapezeka pa mfundo imodzi kapena zingapo zotulutsa. PWR1 ndi PWR2 amayatsidwa ngati mphamvu ya loop ilipo. Module ya 3806E High Current (AO) imakonzedwa kuti igwiritse ntchito makina a turbomachinery. Ma module a analogi otulutsa amathandizira kuthekera kwa hotspare komwe kumalola kusintha kwapaintaneti kwa module yolakwika.

Magawo a analogi otulutsa amafunikira gulu losiyana lakunja (ETP) lokhala ndi mawonekedwe a chingwe ku Tricon backplane. Module iliyonse imayikidwa mwamakina kuti iteteze kuyika kolakwika mu chassis yokonzedwa.
