1756-IRT8I 模拟输入模块 用于电阻温度检测器热电偶和毫伏输入

Allen-Bradley 1756-IRT8I是一个ControlLogix模拟输入模块，具有八(8)个可配置的通道，用于电阻温度检测器(RTD)、热电偶和毫伏输入。

该模块通过适马-德尔塔法实现高分辨率模数转换。转换后的数据保存到IEEE 32位浮点。人机界面(HMI)、监控和数据采集(SCADA)以及分布式控制系统(DCS)可以理想地访问转换后的数据。除了基于计算机的系统之外，信号数据可以用于计算，以及用于控制器的过程变量(PV ),例如比例+积分+微分(PID)。

该模块能够进行开路检测，热电偶输入和3线RTD的检测时间为2秒，4线RTD的检测时间为5秒。

Allen-Bradley 1756-IRT8I is a ControlLogix analog input module with eight (8) configurable channels for resistance temperature detector (RTD), thermocouple, and millivolt inputs.

The module realizes high resolution analog-to-digital conversion by Sigma Delta method. The converted data is saved to IEEE 32-bit floating point. Human Machine interfaces (HMI), supervisory control and Data acquisition (SCADA), and distributed control systems (DCS) are ideal for accessing the converted data. In addition to computer-based systems, signal data can be used for computation, as well as process variables (PVS) for controllers, such as ratio + integral + differential (PID).

The module is capable of open circuit detection with thermocouple input and 3-wire RTD detection time of 2 seconds and 4-wire RTD detection time of 5 seconds.
