zvigadzirwa

4 kusvika 20 mA sosi. Imwe neimwe inobuda chiteshi inotyaira mutoro wekunze uye inogadzira 0 kusvika 20 mA inobuda. Transmitter simba kubva kune yega yega module diode OR'd pamwe chete mudhindadhadhadhata kuti ive nechokwadi chakawandisa simba. Iyo microprocessor yemodule yega yega inoita analog I/O application chirongwa, pamwe nekuchengetedza nzira dzinosimbisa hutano hweFBM. Input chiteshi sarudzo dzinosanganisira inogadziriswa sarudzo yekubatanidza nguva pane yega module. Input chiteshi chengetedzo inokwidziridzwa nekuwedzeredza simba rekuisa yazvino loop kubva pane yega yega magetsi emagetsi mune yega module yevaviri. Sarudzo dzinogadziriswa mumamodule ekuchengetedzwa kwekubuda dzinosanganisira Fail-Safe Action (Bata/Fallback), Analog Output Fail-Safe Fallback Data (pane imwe chiteshi), Fieldbus Fail-Safe Enable, uye Fieldbus Fail-Safe Kunonoka Nguva. Iyo Analog Output Fail-Safe Fallback Data sarudzo inofanirwa kusetwa kune 0 mA inobuda. Izvi zvinobvisa imwe yeaviri easina kubuditsa chiteshi kubva kushumiro yezvinetso zvinoonekwa senge module isinganyatso gamuchira inobuda inonyora kana kusapasa bvunzo dzekuchengetedza paFBM microprocessor inonyora kune anoburitsa marejista. Kugadzika kweAnalog Output Fail-Safe Fallback Data sarudzo ye0 mA inobuda zvakare inoderedza mukana we "foil high" mhedzisiro. KUNYANYA KWAKAKAKURU Nokuda kwehupamhi hwepamusoro, iyo module inosanganisira sigmadelta converters kune imwe neimwe chiteshi, iyo inopa mitsva yeanalog yekuverenga kuverenga yega yega 25 ms, uye inogadziriswa nguva yekubatanidza kubvisa chero ruzha rwekuita uye magetsi emagetsi ma frequency. Nguva yega yega, iyo FBM inoshandura imwe neimwe analog yekuisa kune kukosha kwedhijitari, mavhareji aya makoshero mukati menguva yenguva uye inopa kukosha kweavhareji kune mutongi. KUTENDESEKA KWAKURU Kudzokororwa kweiyo module pair, pamwe nekuvharika kwepamusoro kwezvikanganiso, kunopa yakanyanya kukwira subsystem kuwanikwa nguva. Iyo Redundant Adapter inopa bvunzo mapoinzi anogona kushandiswa ku periodic bvunzo uye kuyerwa kweiyo inobuda voltage yega yega transmitter magetsi. Kuedza kwakadai nguva nenguva kunogona kuwedzera kuwanikwa kwehuwandu hwemodule. STANDARD DESIGN FBM205 ine rugged extruded aluminium yekunze yekudzivirira kwemuviri kwemaseketi. Enclosures dzakanyatsogadzirirwa kukwirisa maFBMs dzinopa akasiyana siyana ekuchengetedza kwezvakatipoteredza, kusvika kune yakaoma nharaunda, maererano neISA Standard S71.04. ZVINOTAURWA ZVINOTAURWA Zviedza-emitting diodes (LEDs) akabatanidzwa kumberi kwemodule anopa zviratidzo zvinoonekwa zveFieldbus Module mabasa. ZVINYORE KUBVISA/KUTSVANISWA Chero module inogona kutsiviwa pasina kushatisa kupinza kwemunda kana masaini ekubuda kune yakanaka module. Iyo module inogona kubviswa / kutsiviwa pasina kubvisa munda mudziyo kumisa cabling, simba, kana kutaurirana cabling. FIELDBUS COMMUNICATION A Fieldbus Communications Module kana Control Processor inopindirana kune isingachashandiswi 2 Mbps module Fieldbus inoshandiswa neFBMs. Iyo FBM205 inogamuchira kutaurirana kubva kune chero nzira (A kana B) ye2 Mbps Fieldbus - kana nzira imwe ikatadza kana kuchinjirwa padanho rehurongwa, moduru inoenderera mberi nekutaurirana pamusoro penzira inoshanda.
