Kakaretšo
Isolated polokeho lepheko ka phumano lehlakoreng: PHD-12TF-288, dijethale input le dipholo tsa, input e le 'ngoe le dipholo tsa habeli.
^ Lepheko le le arogilego le ka fetolela switšhi ya kgauswi le tsenyo ya kgokagano lefelong le kotsi go leswao la go ntšha transistor gomme la e fetišetša lefelong le le bolokegilego. The dipholo tsa transistor pakeng tsa ec e hlomelloa le kgetho switjha ya "inverted mohato / tloaelehileng mohato" , ho phaella moo, ho na le input pontšo potoloho khutšoanyane kapa bulehileng potoloho alamo pontshi, potoloho e fana ka input kutlo phepelo matla.
^ Setšweletšwa se se hloka phepelo ya mohlagase ya ka ntle ya 20-35VDC.
^ Sešupo sa maemo a leswao se beakantšwe ka seetša se se khubedu le se se serolane go bontšha maemo a go šoma a relay ya go ntšha, ge e le ya go tšhoša gona lebone le le khubedu, nakong ya tšhomišo ya tlwaelo lebone le le serolane.
* Phepelo ya mohlagase ya pese, hle bona mametletšo bakeng sa dintlha.
