A. aiki karshen keɓe tsaro ƙofar da kuma aiki ka'idar:

Aikin keɓaɓɓen tsaro na aiki shine fitar da siginar (4 ~ 20) mA daga mai daidaitawa zuwa kowane mai aiki bayan keɓaɓɓen, kuma iyakance haɗarin makamashi daga tashar haɗari zuwa wuraren haɗari. Ka'idar aiki na keɓaɓɓen tsaro na aiki ya shafi keɓaɓɓen siginar da iyakancewar makamashi mai haɗari. Yana amfani da tsarin kewayawa wanda ke raba shigarwa, fitarwa da kuma wutar lantarki tsakanin bangarori uku, wanda ya dace da buƙatun iyakance makamashi na wannan nau'in tsaro. ‌
