Allen-Bradley罗克韦尔AB模块1794-IRT8XT软启动器模块是一种高性能的工业控制组件，以下是其主要特点和功能：

模块功能：1794-IRT8XT模块由Allen-Bradley在其FLEX I/O系列中设计和制造，作为热电偶、RTD（电阻温度检测器）和毫伏输入模块。该模块有8个模拟输入，可以接受毫伏源输入、热电偶输入以及2线、3线和4线RTD输入。

应用环境：该模块不应用于有腐蚀性空气和大量液体的工业环境，因为它没有保护性保形涂层。

操作特性：Allen-Bradley 1794-IRT8 XT FLEX I/O模块具有一些有用的操作特性，如支持长热电偶接线、支持接地和未接地热电偶、良好的共模抑制功能以及检测超量程、欠量程和断线情况。

隔离特性：它在用户24伏DC电压源和用户I/O之间以及模块的用户侧和系统侧之间具有隔离。

兼容性：只要模块与控制网络、以太网/IP和远程I/O通信网络一起使用，B系列模块将被A系列模块的终端基座接受，而不会触发“电子钥匙不匹配警告”。

通信网络：该模块可以与控制网络、以太网/IP和远程I/O通信网络一起使用。

安装和接线：1794 FLEX I/O模块具有模块化设计，可以独立、灵活地选择I/O、终端类型和网络接口。支持带电插拔 (RIUP)，允许用户在系统运行期间更换模块，连接线缆。

模拟模块特性：1794 FLEX I/O模拟模块具有可单独配置的通道，许多模块上都具有可选择的输入滤波器，单端或差分输入，板载整定，内部校准，提供热电偶、热电阻和HART（可寻址远程传感器数据通路）模块。

这些特性使得1794-IRT8XT模块在工业自动化领域中具有广泛的应用前景。

Allen-Bradley Rockwell AB Module 1794-IRT8XT Soft Starter module is a high performance industrial control module, the following are its main features and functions:

Module functions: The 1794-IRT8XT module was designed and manufactured by Allen-Bradley in their FLEX I/O series as a thermocouple, RTD (resistance temperature detector) and millivolt input module. The module has eight analog inputs and can accept millivolt source inputs, thermocouple inputs, and 2-wire, 3-wire, and 4-wire RTD inputs.

Application environment: The module should not be used in industrial environments with corrosive air and large amounts of liquids, as it does not have a protective conformal coating.

Operating characteristics: The Allen-Bradley 1794-IRT8 XT FLEX I/O module has some useful operating features, such as support for long thermocouple wiring, support for grounded and ungrounded thermocouples, good common-mode rejection, and detection of overranges, underranges, and wire breaks.

Isolation feature: It has isolation between the user 24 volt DC voltage source and the user I/O and between the user side and the system side of the module.

Compatibility: As long as the module is used with the control network, Ethernet /IP and remote I/O communication network, the B-Series module will be accepted by the terminal base of the A-Series module without triggering the "electronic Key mismatch warning".

Communication Network: This module can be used with control networks, Ethernet /IP, and remote I/O communication networks.

Installation and wiring: The 1794 FLEX I/O module has a modular design that allows for independent and flexible choice of I/O, terminal type and network interface. Live plug and plug (RIUP) support, allowing users to replace modules and connect cables while the system is running.

Analog module Features: The 1794 FLEX I/O analog module has individually configurable channels, selectable input filters on many modules, single-ended or differential inputs, onboard tuning, internal calibration, thermocouple, thermal resistance, and HART (addressed remote sensor data path) modules.

These characteristics make the 1794-IRT8XT module have a wide application prospect in the field of industrial automation.
