Isishwankathelo
Isignali yonxibelelwano ye-PHD-11TC-11 igalelo kwisithintelo sokhuseleko esizimeleyo, esinokuqonda indlela yokunxibelelana kwe-RS-485 Half Duplex yedijithali kwindawo eyingozi kunye nommandla okhuselekileyo. Isekethe ibonelela ngokusasazwa kwamandla kwizixhobo ezikwisiza. Ixabiso le-voltage lingatshintshwa ngokucofa okuphezulu. Indlela yokusebenza ethile iboniswe kwitshathi engezantsi.
Le mveliso idinga unikezelo lwamandla oluzimeleyo, kwaye unikezelo lwamandla, igalelo kunye nemveliso yodwa.

Ubungakanani
Umzobo weSchematic
Phawula:
1. Umsebenzi kaloliwe wamandla ngumsebenzi ozikhethelayo, kwaye abasebenzisi kufuneka bachaze indlela yonikezelo lwamandla xa bebeka umyalelo.
Ukukhethwa kweziqhagamshelo zikaloliwe zamandla kunokubhekisa kwiphepha lama-89 le "Isihlomelo"
