ISO V-4-20mA and ISO R-P-O series isolation transmitter is a displacement resistance signal according to the size of the change in isolation into a standard signal with the value of the resistance into a linear hybrid integrated circuit. The circuit integrates a set of multi-channel high isolation DC/DC power supply, several high-performance signal isolators and resistance linearization, long line compensation, interference suppression circuit on the same chip, which is especially suitable for the isolation of resistance signals into standard signals, displacement signals, transmission and distortion-free telecommunication, industrial field electronic ruler, angle sensors, signal isolation, acquisition and conversion. Chip internal integration of high-efficiency DC-DC, can produce two groups of mutually isolated power supply to the internal input amplifier circuit, modulation circuit power supply and output demodulation circuit, conversion circuit, filter circuit power supply. SMD process structure and new technology isolation measures so that the device can achieve: the working power supply, the signal input and output of the triple isolation of the 2500VAC, and to meet the industrial level of wide temperature, ISO V-4-20mA and ISO R-P-O series displacement signal isolation amplifier is very convenient to use, only a few external components, can realize the displacement resistance signal isolation transmission. And can realize the industrial field displacement control signal one into two out, one into four out of the function.SY series of input, output non-isolated products, with high precision and linearity (better than 0.05F.S), commonly used in built-in electronic ruler, angular displacement signal transmitter and other precision measuring instruments. The product is small in size, easy to install, and can be placed inside the sensor to convert displacement and angle signals directly into standard 4-20mA signals, and the fullness and zero point can be adjusted and calibrated by the user through external potentiometers.
