Page 7: Product Description
Functional Safety KFD2-SOT3-Ex*, KFD2-ST3-Ex* Product Description Product Description Function General This isolated barrier is used for intrinsic safety applications. The device transfers digital signals (NAMUR sensors or dry contacts) from a hazardous area to a safe area. Via switches the mode of operation can be reversed and the line fault detection can be switched off. -
