ISOLATED BARRIERS DIN RAIL MOUNTED
K-System isolated barriers guarantee safe, reliable, and effi cient signal transmission between your fi eld device and the control system. In addition to their inherent power limitation, these modules feature galvanic isolation between the signal loop and all other power loops. Pepperl+Fuchs off ers the most complete range of products to meet all your application and installation requirements.
