PACSystems智能8通道RTD-张力桥使用指南（中文）
此板卡是一种智能的,8-通道,低电压输入板,它是为应用于张力电桥或RTD输入而专门设计的.这种板提供所有必要信号条件,多路技术,数字化及数字信号处理.一个16字节板处理器控制所有板的功能并执行所有必要的信号处理.
桥板可以同时配置张力电桥和RTD输入信号.张力电桥和RTD输入通过仪表板前面的P3连接器接线..一个板上A/D转换器将每个输入信号数字化为一个12字节的加号数据指令,此指令经过数字化处理产生了最终的输出数据.此板为两种类型的RTD提供线性化,并为每一个RTD通道供电..
下面为模块的主要特性
□八个独立的输入通道
□RTD输入信号线性化
□RTD补偿导线标准
□张力电桥标准尺度补充
□板上16字节微机
□主机上部最小化的双端口数字寄存器
□公共模式：70 dB at 60 Hz
□校准参数消除掉偏移量并加进电位计的非易失性存储

high reliability, strict industrial application practice, more than 1000 sets of application performance in China;
4. It has good openness, flexibility and scalability;
Fifth, the project is easy, the interface is friendly, and the maintenance is simple;
2. Industria1″ system communication
Industrial” system uses international standard industrial bus. Field controller supports Profibus, FF, ModBus, Can, etc.
International standard fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system through the
