ZOCHITIKA PA FBM201/b/c/d Gawo Lolowetsamo la Analogi lililonse lili ndi mayendedwe asanu ndi atatu a analogi, tchanelo chilichonse chimalandira mawaya a 2, DC kuchokera ku sensa ya analogi monga 4 mpaka 20 mA kapena 0 mpaka 5V transmitter, kapena gwero lodzipangira mphamvu la 20 mA. Ma modules amachita kusintha kwa siginecha komwe kumafunikira kuti agwirizane ndi ma siginecha amagetsi olowera kuchokera ku masensa am'munda kupita ku fieldbus yosafunikira. Mukalumikizidwa ku ma TA oyenerera, gawo la FBM201 limapereka magwiridwe antchito omwe amaperekedwa kale ndi 100 Series FBM I/O subsystem. Ma TA alipo omwe amathandizira magwiridwe antchito a 100 Series FBM01 pomwe FBM01 ikugwiritsidwa ntchito ndi zida zomwe si za HART®. ZOCHITIKA ZOPHUNZITSIRA Ma module a FBM201/b/c/d ali ndi kamangidwe kocheperako, kokhala ndi aluminiyamu yakunja yolimba kuti atetezere mabwalo. Malo otchingidwa mwapadera kuti akhazikitse ma FBM amapereka magawo osiyanasiyana achitetezo cha chilengedwe, mpaka malo ovuta malinga ndi ISA Standard S71.04. KUSINTHA KWAMBIRI Kuti mukhale olondola kwambiri, ma modules amaphatikizapo kutembenuka kwa data ya sigmadelta pa njira iliyonse, yomwe ingapereke chidziwitso chatsopano cha analogi powerenga 25 ms iliyonse, ndi nthawi yosakanikirana yosakanikirana kuchotsa phokoso lililonse la ndondomeko ndi phokoso lafupipafupi lamagetsi. Nthawi iliyonse, FBM imatembenuza kuyika kwa analogi kumtundu wa digito, kuwerengera mitengoyi pakapita nthawi, ndikupereka mtengo wapakati kwa wowongolera. KUCHOKERA KWAMBIRI / KUSINTHA KWAMBIRI Ma modules amatha kuchotsedwa / kusinthidwa popanda kuchotsa cabling yoyimitsa chipangizo, mphamvu kapena mauthenga. ZOCHITIKA ZOSANGALALA Ma diode otulutsa kuwala (Ma LED) ophatikizidwa kutsogolo kwa ma modules amapereka ziwonetsero za ntchito za Fieldbus Module (FBM). KUPWIRITSA NTCHITO YOPHUNZITSIRA ZOPHUNZITSA Ma modules amakhazikika pa pulani yoyambira (onani Chithunzi 1) yomwe imakhala ndi ma FBM anayi kapena asanu ndi atatu. The modular baseplate mwina ndi DIN njanji wokwera kapena rack wokwezedwa, ndipo imaphatikizapo zolumikizira ma siginecha za ma fieldbus osafunikira, mphamvu zodziyimira pawokha za dc, ndi zingwe zoyimitsa. FIELDBUS COMMUNICATION A Fieldbus Communication Module kapena Control Processor imalumikiza module yotsalira ya 2 Mbps Fieldbus yogwiritsidwa ntchito ndi FBMs. Ma module a FBM201/b/c/d amavomereza kulumikizana kuchokera kunjira iliyonse (A kapena B) ya 2 Mbps fieldbus yofunikira - ngati njira imodzi ikalephera kapena kusinthidwa pamlingo wadongosolo, gawoli likupitilizabe kulumikizana panjira yogwira. TERMINATION ASSEMBLIES Zizindikilo za Field I/O zimalumikizana ndi kagawo kakang'ono ka FBM kudzera pa ma TA a DIN njanji (onani Chithunzi 1). Ma TA omwe amagwiritsidwa ntchito ndi ma module a FBM201/b/c/d akufotokozedwa mu “TERMINATION ASSEMBLIES AND CABLES” patsamba 8.
