23.1.6 Ukudambisa nokushelela Ukudambisa nokushelela kokubili kuyimisebenzi yokuhlunga, elungisekayo, futhi enemiphumela ehlukene endleleni isignali yokufaka icutshungulwa ngayo. • Ukudambisa kubangela ukuhlunga okujwayelekile kwe-single-pole, i-low-pass efana nenethiwekhi ye-RC. • Ukushelela kubangela ukudambisa 'okuhlakaniphe' kakhulu lapho izinguquko ezincane (umsindo) zicindezelwa kakhulu futhi izinguquko ezinkulu (ukuthambekela) zicutshungulwa ngokujwayelekile. Nakuba, amanani aphezulu okudambisa azocindezela kakhulu umsindo futhi enze isignali yokuphumayo izinze, kubangela isikhathi sokuphendula esinensayo. Umsebenzi wokushelela ugwema lokhu kungalungile ngokususa ukuhlunga kuyilapho kukhona izinguquko zesignali ezinkulu kakhulu kokokufaka. Amanani aphakeme wokudambisa ayanconywa kumasiginali okokufaka okunensa adinga amazinga aphezulu okuzinza, kuyilapho amasiginali asheshayo edinga amanani aphansi okuswakama. Uma ungabaza, okunye ukuhlola kuzoveza imiphumela engcono kakhulu. 23.1.7 Amasignali e-alamu Amasignali e-alamu angalungiselelwa ukushayela imisinga yokuphuma kwe-analogi ngaphandle kwebanga lokusebenza. • I-alamu ephansi ishintsha okukhiphayo kube ngu-1.00 mA futhi • I-alamu ephezulu ishintsha yamanje ibe ngu-21.00mA. Kunezinhlobo ezintathu zephutha ezicupha ukusabela kwe-alamu: • I-alamu ye-O/C - i-alamu iyasayinwa uma isekethe evuliwe ensimini itholwa. • I-Tx Fail - i-alamu isayina uma iphutha litholwa. • I-Cj Fail - i-alamu isayinda uma kutholwa iphutha ngenzwa ye-Cj. Isistimu yamandla ye-Meanwell Ukuqapha i-voltage ye-DC, othintana naye wamahhala odluliswayo unikezwa okubhalwe 'DC OK.'
