产品详细资料
此表列出了3706A型热电偶输入模块的规格。警告：如果超过某个通道的共模电压范围，Invensys将无法保证模块的正常运行和其他通道的准确性。注意：快速或连续变化的输入可能会导致读数比较错误，因为三个通道的测量值可能相差满量程的0.5%以上，这可能会导致错误地宣布故障。支持J、K、T的热电偶类型开路检测终端模块上选择的上/下标度输入信号数量32差，直流耦合输入更新率支持的热电偶类型和温度范围的大精度为50ms。见表59 3706A型热电偶类型的精度（75页）。输入电阻（负载）22 MΩ（DC），典型输入点保护110 VAC连续无损坏噪声抑制：共模-85 dB@0–60 Hz小值-95 dB@60 Hz典型噪声抑制：正常模式-17 dB@60赫兹共模范围（见上述警告）±10 VDC大值（通道对通道或通道对地）通道对通道隔离200 kΩ，典型的参考接点补偿范围为32°至140°F（0°至60°C）模块状态指示灯通过、故障、激活输入诊断故障范围b：小输入变化输入变化采样周期错误比较的小周期为满量程的0.5%50毫秒256个采样逻辑功率<10瓦
This table lists the specifications for Model 3706A, which is a Thermocouple Input Module. WARNING If the common mode voltage range of a channel is exceeded, Invensys does not guarantee proper operation of the module and accuracy of other channels. CAUTION Rapidly or continuously changing inputs may cause mis-compare readings because the measured values of the three channels may be different by more than 0.5 percent of full scale, which may cause a fault to be declared in error.Thermocouple types supported J, K, T Open detect Upscale/downscale selected on termination module Number of input signals 32 differential, DC-coupled Input update ratea 50 ms maximum Accuracy of thermocouple types and temperature ranges supported See Table 59 Accuracy of Model 3706A Thermocouple Types (page 175).
