Kutulutsa kwa transistor yolowera Zotchinga zodzipatula zimatumiza zizindikiro zolowera kuchokera ku ma contact olumikizana kapena ma switch oyandikira m'dera loopsa kudzera mu zotchinga zodzipatula kupita kumalo otetezeka okhala ndi ma transistor outputs. Cholowetsacho chimawongolera kutulutsa kwa transistor passive komwe kumakhala ndi makhalidwe otsutsa. Chotulutsacho chili ndi magawo anayi odziwika: kukana kwa alamu yafupikitsa ≤ 240 Ω, chizindikiro chimodzi 1.4KΩ ≤ mtengo wotsutsa ≤ 1.6KΩ, chizindikiro cha 0 13KΩ ≤ mtengo wotsutsa ≤ 14KΩ, ndi kukana kwa alamu yosweka > 100KΩ. Khalidwe lotulutsali limayankha mkhalidwe wa mzere pa mzere wa chizindikiro. Ma switch odumpha a module amagwiritsidwa ntchito kukhazikitsa zolowetsa ndi zotulutsa mbali imodzi kapena kulamulira kobwerera m'mbuyo, komanso kukhazikitsa ntchito yowonetsa alamu yolakwika ya mzere. Chogulitsachi chimafuna magetsi odziyimira pawokha, okhala ndi magetsi odzipatula, ma input, ndi ma output terminals.
