New thermal resistance temperature isolation trans

Shunyuan science and technology newly launched thermal resistance temperature isolation transmitter ic

sunyuan isoz-w series isolation transmitter is a hybrid integrated circuit that converts the thermal resistance signal into a linear standard signal according to the temperature. This circuit integrates a group of multi-channel highly isolated dc/dc power supplies, several high-performance signal isolators, thermal resistance linearization, long-line compensation and interference suppression circuits on the same chip, which is especially suitable for PT100 thermal resistance signal isolation and conversion into standard signal, temperature signal transmission and distortion free remote transmission, and temperature signal acquisition and isolation of industrial field PLC or DCS system

high efficiency DC-DC is integrated in the chip, which can generate two sets of mutually isolated power supplies to supply power to the internal input amplification circuit, modulation circuit and output demodulation circuit, conversion circuit and filter circuit respectively. SMD process structure and new technical isolation measures enable the device to achieve 3000vdc three isolation of power supply and signal input/output. And it can meet the requirements of industrial wide temperature, humidity and vibration on site

isoz-w series temperature signal isolation amplifier is very convenient to use, and only a few external components are required to realize the isolation and transmission of Pt100 thermal resistance signal. It can also realize the function of one in, two out and one in, four out of the industrial field temperature control signal

application scheme:

the application of sunyuanisoz-w series can always provide us with reliable data support. Isolation transmitter and sunyuanisoem series isolation amplifier can easily realize one-way input and multi-way output of thermal resistance signals.

principle of one-way input and multi-way output application scheme: connect the output signal of isoz-w isolation transmitter to the input end of isoem isolation amplifier, and the isoem isolation amplifier will transmit A group of signals completely isolated from the input end is generated, thus realizing the output of one circuit of thermal resistance signal. Since the operator can only work for 59H a week, the output of two mutually isolated standard signals. Similarly, connect the output signal of isoz-w isolation transmitter to the input terminals of multiple isoem isolation amplifiers, and each isoem isolation amplifier will output a group of signals completely isolated from the input terminals, thus realizing the input of one thermal resistance signal and the output of multiple mutually isolated standard signals

for one circuit of thermal resistance signal input and two circuit of signal output, please refer to the following application scheme:

application scheme 1: one circuit of thermal resistance signal input and two circuit of voltage signal output

one circuit of Pt100 signal input (temperature range ℃) is realized by using module isoz1-w3-p1-o4 and module isoem-u1-p1-o5, and

two circuit of isolated voltage signal output, one circuit of which outputs 0~5v signal and the other circuit outputs 0~10v signal. Connect the output of module isoz1-w3-p1-o4 to the input of module isoem-u1-p1-o5

the application party but the United States decided to impose tariffs on the steel and aluminum products of these three economies from June 1. Case 2: one circuit of thermal resistance signal input and two circuit of current signal output

one circuit of Pt100 signal input (temperature range ℃) is realized by using the module isoz1-w2-p1-o1 and the module isoem-a4-p1-o1, and two circuits of isolated ma current signal output. That is, connect the output terminal of module isoz1-w2-p1-o1 to the input terminal of module isoem-a4-p1-o1, and then output ma current signal. At the same time, isoem-a4-p1-o1 also outputs a group of output ma current signals
