Keɓaɓɓen shingen tsaro a gefen ganowa: PHD-22TF-2727, shigarwar dijital da fitarwa, shigarwar dual da fitarwa biyu.
Keɓaɓɓen shingen zai iya canza canjin kusanci da shigar da lamba a cikin wuri mai haɗari zuwa siginar sadarwa da watsa shi zuwa wuri mai aminci.
An sanye take da fitarwar fitarwa tare da canjin zaɓi na yanayin "ON/KASHE". Bugu da ƙari, akwai alamar shigarwar gajeriyar hanya ko alamar ƙararrawa ta buɗewa, kewayawa yana ba da wutar lantarki don firikwensin shigarwa.
Wannan samfurin yana buƙatar samar da wutar lantarki na 20-35VDC na waje.
An saita alamar alamar sigina a cikin haske mai ja da rawaya don nuna matsayin aiki na relay na fitarwa, lokacin da yake ƙararrawa to hasken yana ja, yayin aiki na yau da kullun hasken rawaya ne.
