1756-IR6I 温度测量模拟模块 用于电阻-温度检测器(RTD)传感器

概述：

Allen-Bradley 1756-IR6I是一个温度测量模拟模块。这是一个模拟模块，用于电阻-温度检测器(RTD)传感器。

1756-IR6I模块提供整数模式和浮点模式两种数据格式。当选择整数模式时，集成的特性是多输入范围，陷波滤波器和实时采样。浮动模式包括所有这些功能，加上温度线性化，过程报警，速率报警和数字滤波。它也有可选择的温度单位，如摄氏度或华氏度。模块有四(4)种可能的输入范围，包括1到487 m?， 2 ~ 1000 m?;4 ~ 2000米;8 ~ 4000米;这些范围指定了模块可检测的最小和最大信号。它有六(6)个单独隔离的RTD输入和16位的分辨率。实际分辨率包括7.7 m?位为1-487欧姆;15米?/位，2-1000欧姆，30米?/bit 4 - 2000欧姆和60 m?/bit适用于8 - 4020欧姆。该模块的陷波滤波线噪声滤波。确保选择与应用程序预期噪声频率密切匹配的滤波器。数字滤波器通过消除每个输入通道上的瞬态噪声来平滑数据。

1756-IR6I的实时采样功能允许模块通过扫描其所有输入通道收集多播数据。为了使能组播功能，需要配置RTS (Real-Time Sampling)周期和RPI (request Packet Interval)周期。

该模块还嵌入了保护功能，例如范围不足/超过范围检测，该模块的功能用于监测输入信号是否超出了输入范围设置的限制。进程警报的工作原理类似，但是进程限制是由用户手动设置的。集成的速率报警允许模块在短时间内检测快速上升或下降。速率报警仅在使用浮点数的应用程序中可用。断线检测功能提供环路接线完整性。它可以检测RTB或模块中的导线是否已断开。

10欧姆铜RTD中的小偏置误差可以通过模块的10欧姆偏置特性进行补偿。还可以为模块中的每个通道配置传感器类型。这将模拟信号线性化成一个温度值。

Allen-Bradley 1756-IR6I is a temperature measurement simulation module. This is an analog module for resistance-temperature detector (RTD) sensors.

The 1756-IR6I module provides two data formats, integer mode and floating-point mode. When the integer mode is selected, the integrated features are multiple input ranges, notch filters, and real-time sampling. The floating mode includes all of these features, plus temperature linearization, process alarm, rate alarm, and digital filtering. It also comes in selectable temperature units, such as degrees Celsius or Fahrenheit. The module has four (4) possible input ranges, including 1 to 487 m? , 2 ~ 1000 m? ; 4 ~ 2000 m; 8 ~ 4000 m; These ranges specify the minimum and maximum signals that the module can detect. It has six (6) individually isolated RTD inputs and a 16-bit resolution. Actual resolution includes 7.7 m? The bits are 1-487 ohms; 15 meters? Per bit, 2-1000 ohms, 30 meters? /bit 4-2000 ohms and 60 m? /bit is suitable for 8-4020 ohms. The module of notch filter line noise filter. Make sure to select a filter that closely matches the expected noise frequency of the application. Digital filters smooth the data by eliminating transient noise on each input channel.

The 1756-IR6I's real-time sampling feature allows the module to collect multicast data by scanning all of its input channels. To enable multicast, you need to configure the Real-Time Sampling (RTS) period and the request Packet Interval (RPI) period.

The module also has embedded protection features such as under-range/out-of-range detection, the module's function is to monitor if the input signal exceeds the limits set by the input range. Process alerts work similarly, but process limits are set manually by the user. An integrated rate alarm allows the module to detect rapid rises or falls in a short period of time. Rate alarms are only available in applications that use floating-point numbers. The break detection function provides loop connection integrity. It can detect whether the wires in the RTB or module have been disconnected.

Small bias errors in the 10 ohm copper RTD can be compensated by the 10 ohm bias characteristics of the module. You can also configure sensor types for each channel in the module. This linearizes the analog signal to a temperature value.
