Function: KFA6-SR2-Ex2.W.IR

This isolated barrier is used for intrinsic safety applications.

The device is used for level control, pump control and other switching applications.

The device transfers digital signals from NAMUR sensors or dry contacts from the hazardous area to the non-hazardous area.

The device is easily configured by the use of DIP switches.

A fault is signalized by LEDs.
