Keɓaɓɓen shingen tsaro a gefen ganowa: PHD-12TF-288, shigarwar dijital da fitarwa, shigarwa guda ɗaya da fitarwa biyu.
^ Keɓaɓɓen shingen zai iya canza canjin kusanci da shigar da lamba a cikin wuri mai haɗari zuwa siginar fitarwa ta transistor kuma aika shi zuwa wuri mai aminci. Fitar transistor tsakanin ec yana sanye da zaɓin zaɓi na "lokacin jujjuyawar lokaci / lokaci na al'ada", Bugu da ƙari, akwai alamar shigarwar gajeriyar kewayawa ko alamar ƙararrawa mai buɗewa, da'ira tana ba da damar shigar da wutar lantarki.
^ Wannan samfurin yana buƙatar wutar lantarki ta 20-35VDC ta waje.
^ An saita alamar sigina a cikin haske mai launin ja da rawaya don nuna matsayin aiki na relay na fitarwa, lokacin da yake don tsoratarwa to hasken yana ja, yayin aiki na yau da kullum hasken yana rawaya.
