General Description

TK8000-Ex repeating current input and output barrier，can prevent dangerous energy fleeing from the safe side to a dangerous place. And the 4 ~ 20 mA DC signal can be converted linearly to 4 ~ 20 mA DC signal output after energy restriction (see function diagram). After hazardous energy is restored, it can automatically resume normal operation, which is different from other Zener barriers.
