Tšitiso e ikhethileng ea polokeho lehlakoreng la ho lemoha: PHD-12TF-288, tlhahiso ea dijithale le tlhahiso, tlhahiso e le 'ngoe le tlhahiso e habeli.
^ Thibelo e ka thōko e ka fetola mochine oa ho atamela le ho kenya letsoho sebakeng se kotsi ho letšoao la tlhahiso ea transistor ebe o le fetisetsa sebakeng se sireletsehileng. Transistor e hlahisoang pakeng tsa ec e na le sesebelisoa sa khetho ea "inverted phase / normal phase" , ho phaella moo, ho na le pontšo e khutšoanyane ea pontšo kapa pontšo ea alamo e bulehileng ea potoloho, potoloho e fana ka matla a ho kenya letsoho.
^ Sehlahisoa sena se hloka matla a kantle a 20-35VDC.
