Function

This Surge Protection Barrier is designed for use with K-System (KF modules).
By simply snapping the barriers into a standard KF module, the modules are safely protected against voltage surges of different origin (e. g.
lightning stroke, switching impulse, etc.). This is achieved by diverting the transient current to ground and limiting the signal line voltage to a safe
level for the duration of the surge.
The end digits of the model designation correspond to the protected terminals of the respective KF module.
For additional information, refer to the manual and www.pepperl-fuchs.com.

Note: Surge Protection Barriers must always be connected to a solid and effective ground and be at the same equipotential level as the
instrument it is protecting. The ground system must comply with all applicable regulations.
