Katangar tsaro da aka keɓe tare da aikin kariyar ƙaruwa na fitowar transistor na shigarwar maɓalli, wanda ke keɓancewa da aika siginar shigarwa daga lambobin maɓalli ko maɓalli na kusanci a wurare masu haɗari zuwa yankin aminci tare da transistor na fitarwa ta hanyar shingen aminci. Ana samun gano matsalar layi ta hanyar LED a saman module ɗin. Ana amfani da maɓallin kira na module don saita shigarwa da fitarwa a cikin lokaci ko sarrafawa na baya, da kuma kunna ko kashe aikin alamar faɗakarwar gano matsalar layi. Wannan samfurin yana buƙatar samar da wutar lantarki mai zaman kanta, tare da samar da wutar lantarki mai keɓewa, shigarwa, da tashoshin fitarwa.
