Integrated Circuit Signal Isolated Transmitter for Potentiometer Signal Acquisition / Isolation and Control

SunYuan ISO V-4-20mA and ISO R-P-O series isolation amplifier is a kind of integrated circuit that convert and isolate position resistance signal into standard signal that linear to resistance according to change in size. It integrated a set that multi-channel high isolated DC-DC converter, some high-powered signal isolator, and resistance linearization,long-term compensation, interference suppression circuit in single chip. Especially apply to convert/isolate resistance signalto standard signal, transmission of position signal, Electrical ruler,angular transducer signal isolation, acquisition andconversion.The inner of the chip integrated high-efficiency DC-DC converter that produce two sets isolated power separatelysupply for inner input port amplifier circuit, modulator circuit and output port demodulator circuit, conversion circuit, filtercircuit. SMD technology and new technique quarantine measure made it can achieve among working power supply, signalinput, signal output arrive 2500V AC isolation voltage, and meet industrial site temperature/humidity/vibrationmal-environment requirements.ISO V-4-20mA and ISO R-P-O series position signal isolation amplifier is easy to use, only need a few externalcomponent, then can realize position resistance signal transducer and isolation. And can realize industrial site one in two outand even one in four out.SY series input output non-isolated type product, has high precision and linearity (>0.05F.S), it usually applied inbull-in electrical ruler, angular displacement signal transducer etc, precision measuring instrument. Small size, easy stall. Itcan be installed inner of the sensor, directly convert the position, angular signal to standard 4-20mA signal. Zero and Spancan be adjusted through external potentiometer.
