Isishwankathelo
Isiginali ye-frequency igalelo kwisithintelo sokhuseleko esizimeleyo, esinokuqonda i-1: 1 ukuhanjiswa kwesiginali yesixhobo kwindawo eyingozi kwindawo ekhuselekileyo, kwaye ibonelele ngonikezelo lwamandla olulodwa (12V okanye 24V) kwisixhobo sasendle. kwindawo eyingozi.
Le mveliso idinga unikezelo lwamandla oluzimeleyo, kwaye unikezelo lwamandla, igalelo kunye nemveliso yodwa phakathi komnye nomnye.

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"
