工厂自动化系统中应用的智能传感器和信号整形器的输出必须要与PC、可编程逻辑控制器和监控系统的远程终端等的标准数据采集系统相兼容。标准的模拟输入应为0～1V和±10V,0～1mA和4～20mA。图1所示
The output of smart sensors and signal shapers used in factory automation systems must be compatible with standard data acquisition systems such as remote terminals for PCs, programmable logic controllers and monitoring systems. Standard analog input should be 0 ~ 1V and ± 10V, 0 ~ 1mA and 4 ~ 20mA. Figure 1 shows
