iso z-w-s/d application scheme

iso z-w-s/d series isolation transmitter and ISO EM Series isolation amplifier can easily realize one-way input and multiple output of thermal resistance signal

the principle of the application scheme of single input and multiple output: connect the signal output by the I "so z-w-s/d isolation transmitter to the input end of the ISO EM isolation amplifier, and the ISO EM isolation amplifier will output a group of signals completely isolated from the input end, thus realizing the input of one thermal resistance signal and the output of two mutually isolated standard signals. Similarly, connect the output signal of ISO z-w-s/d isolation transmitter to the input end of multiple ISO EM isolation amplifiers, and each ISO EM isolation amplifier will output a group of signals completely isolated from the input end, so as to realize the input of one thermal resistance signal and the output of multiple mutually isolated standard signals
