模块状态指示灯通过、故障、激活输入诊断故障范围a小输入变化输入变化采样周期错误比较的小周期a快速或连续变化的输入可能会导致错误比较读数,因为三个通道的测量值可能相差满刻度的0.5%以上,这可能会导致故障被宣布为错误。如果输入读数至少相差满量程的0.5%,并持续256个输入样本的小周期,则故障概率增加。本节包括3720型的规格,这是一种电压范围为0至5 VDC的TMR模拟输入模块。3720模块只能安装在Tricon v10.2及更高版本的系统中。注意:3720型可以安装在已升级到v10.2.x或更高版本的低密度系统中。有关更多信息,请参阅Tricon v9–v11系统现场终端指南中的“附录I,低密度机箱I/O模块兼容性”。表23 3720模拟输入规格特性规格颜色代码黄色输入信号数量64,单端输入更新率10ms分辨率12位或14位可编程精度<32°至140°F(0°至60°C)FSR的0.15%输入电阻(负载)10MΩ(DC),断电时的小输入电阻140kΩ(直流),典型通道间隔离420kΩ,典型的正常模式抑制-8 Hz时3 dB-60 Hz时17 dB-120 Hz时23 dB
Module status indicators Pass, Fault, Active Input diagnostic fault coveragea Minimum input change Input change sample period Minimum period of mis-compares a. Rapidly or continuously changing inputs may cause mis-compare readings because the measured values of the three channels may differ by more than 0.5 percent of full scale, which can cause a fault to be declared in error. If the input readings differ by a minimum of 0.5 percent of full scale and continue for a minimum period of 256 input samples, the probability of a fault increases.This section includes specifications for Model 3720, which is a TMR Analog Input Module with a voltage range of 0 to 5 VDC. The 3720 module can be installed only in Tricon v10.2 and later systems. Note The Model 3720 can be installed in low-density systems that have been upgraded to v10.2.x or later. For more information, see “Appendix I, Low-Density Chassis I/O Module Compatibility” in the Field Terminations Guide for Tricon v9–v11 Systems.
