P0922UD FBM203 RTD输入接口模块

紧凑型FBM203/c/d铂/镍/铜RTD输入接口模块包含8个电阻温度检测器(RTD)输入通道。
Compact FBM203/c模块的每个输入通道接受2线或3线RTD传感器输入，电阻范围为0至320欧姆(FBM203)或0至30欧姆(FBM203c)。紧凑型FBM203d的每个输入通道接受4线RTD传感器输入，在0到320欧姆的电阻范围内。每个模拟输入都与其他通道和地电隔离。它是Compact 200系列I/O子系统概述(PSS 41H-2COV)中描述的Compact 200系列I/O子系统的一部分。
这些模块执行所需的信号转换，将来自现场传感器的电气输入信号连接到可选的冗余现场总线。
紧凑型FBM203/c/d模块执行模拟输入应用程序，提供转换时间(以每个模块为基础)和可配置选项
变化率限制。
FBM203c可使用TAs，当使用3线RTD输入时，它支持100系列FBM33A的功能。
ta可用于FBM203d，当使用2线或4线RTD输入时，它支持100系列FBM03B或FBM33B的功能。

8路电阻温度检测器(RTD)输入通道
•每个模拟输入是电隔离的
•紧凑，坚固的设计适用于G3(恶劣)环境的外壳
•执行模拟输入应用程序，提供转换时间和可配置的变化率限制选项
•通过每个通道的sigma-delta数据转换实现高精度
•终端组件(TAs)用于本地或远程连接现场布线到紧凑型FBM203/c/d

为了实现高精度，每个通道都集成了一个Sigma-Delta转换器，它可以每25毫秒为每个通道提供新的模拟输入值，以及一个可配置的集成周期，以消除任何过程噪声和电源线频率。每个时间段，现场总线模块(FBM)将每个模拟输入转换为数字值，在时间段内平均这些值，并将平均值提供给控制器。

FBM203

The Compact FBM203/c/d Platinum/Nickel/Copper RTD Input Interface Modules contain eight resistance temperature detector (RTD) input channels.
Each input channel of the Compact FBM203/c modules accepts a 2- or 3-wire RTD sensor input, within a 0 to 320 ohm (FBM203), or 0 to 30 ohm (FBM203c) resistance range. Each input channel of the Compact FBM203d accepts a 4-wire RTD sensor input, within a 0 to 320 ohm resistance range. Each analog input is galvanically isolated from other channels and ground. It is part of the Compact 200 Series I/O subsystem described in Compact 200 Series I/O Subsystem Overview (PSS 41H-2COV).
The modules perform the signal conversion required to interface the electrical input signals from the field sensors to the optionally redundant fieldbus.
The Compact FBM203/c/d modules execute an analog input application program, which provides conversion time (on a per module basis) and configurable options for
Rate of Change Limits.
TAs are available for FBM203c, which support the functionality of the 100 Series FBM33A when used with a 3-wire RTD input.
TAs are available for FBM203d, which support the functionality of the 100 Series FBM03B or FBM33B when used with a 2-wire or 4-wire RTD input.

8 resistance temperature detector (RTD) input channels
• Each analog input is galvanically isolated
• Compact, rugged design suitable for enclosure in Class G3 (harsh) environments
• Execution of an analog input application program that provides conversion time and configurable options for Rate of Change Limits
• High accuracy achieved by sigma-delta data conversions for each channel
• Termination Assemblies (TAs) for locally or remotely connecting field wiring to the Compact FBM203/c/d

For high accuracy, each channel incorporates a Sigma-Delta converter which can provide new analog input values for each channel every 25 ms, and a configurable integration period to remove any process noise and power line frequencies. Each time period, the Fieldbus Module (FBM) converts each analog input to a digital value, averages these values over the time period, and provides the averaged value to the controller.
