The TFxxxxN series is with preceding voltage signal input and backward voltage/current signal output, and with an inner high efficiency
isolated micro-power source. It can provide isolation power to peripheral circuit at the same time of providing power to internal signal
processing circuit. Adopting electromagnetism isolation technology, therefore compared with photo-coupler isolation, it has higher
accuracy and lower temperature drift. This module is two-port isolation (input and output). There are external functions for the series as
zeros and full adjustment, convenient for customer to design and adjust.
