1769-IF4XOF2 紧凑型I/O模块 具有嵌入式通道

【产品详情】

Allen-Bradley 1769-IF4XOF2是一款紧凑型I/O模块，具有嵌入式通道和组合模拟输入和输出接口。该模块可用作模拟输入模块，与 Allen Bradley 的 MicroLogix 1500 和 1769 CompactLogix 系列控制器兼容。

1769-IF4XOF2 具有成本效益，具有低分辨率转换。它是连接过程变量的理想选择，不需要高水平的临界性或高精度测量。该模块具有嵌入式四 （4） 个模拟输入通道，可配置为单端或差分输入接线。输入通道接受 +10V dc 或 0 至 20 mA 信号类型，而输出以 0 至 10V 直流电压和 0 至 20 mA 电流形式的模拟信号提供模拟信号。输入和输出满范围为 0 至 10.5V 直流和 0 至 21 mA。

输入电路具有通过逐次逼近方法实现的积分模数 （ADC）。它的分辨率为 8 位。该电路将基准输入转换为二进制信号，该信号保存在8位寄存器或字节中。这些数据被称为原始数据，需要信号处理和调节（如缩放）才能转换为工程值来表示实际的过程变量。此数据可供 CPU 循环检索或通过程序触发器检索。

1769-IF4XOF2 的实例数取决于所使用的 1769 CompactLogix 和 MicroLogix 1500 控制器。使用相同的模块或任何组合可以最大化支持的模块数量，但是，必须遵守电源距离额定值。对于 CompactLogix，模块的任何实例与电源的距离不应超过 8 个模块。

Allen-Bradley 的 1769-IF4XOF2 紧凑型 8 位低分辨率模拟 I/O 模块是一款具有四 （4） 个模拟输入点和两 （2） 个模拟输出点的 I/O 模块。它有 4 个单端模拟输入，最大工作电压范围为 0 至 10.5 伏直流，电流范围为 0 至 21 mA。它采用逐次逼近型转换器类型，具有 8 位加符号最大分辨率和每通道 5 毫秒的响应速度。它具有 30 伏交流/30 伏直流工作电压，每通道共模电压 （CMD） 为 10 伏直流，在 60 赫兹和输入之间 1 伏时共模抑制为 60db。1769-IF4XOF2 的电压端标称输入阻抗为 150 kΩ，电流端的标称输入阻抗为 150 Ω。

【英文介绍】

The Allen-Bradley 1769-IF4XOF2 is a compact I/O module with embedded channels and combined analog input and output interfaces. The module can be used as an analog input module and is compatible with Allen Bradley's MicroLogix 1500 and 1769 CompactLogix series controllers.

The 1769-IF4XOF2 is cost-effective with low resolution conversion. It is ideal for connecting process variables without the need for high levels of criticality or high-precision measurements. The module has four (4) embedded analog input channels that can be configured as single-ended or differential input wiring. The input channel accepts the +10V dc or 0 to 20 mA signal type, while the output provides an analog signal in the form of 0 to 10V DC voltage and 0 to 20 mA current. The full range of input and output is 0 to 10.5V DC and 0 to 21 mA.

The input circuit has an integral module (ADC) realized by a successive approximation method. It has an 8-bit resolution. This circuit converts the reference input into a binary signal, which is stored in an 8-bit register or byte. This data is called raw data and requires signal processing and adjustment (such as scaling) to be converted into engineering values to represent actual process variables. This data can be retrieved by the CPU cycle or by a program trigger.

The number of instances of 1769-IF4xof2 depends on the 1769 CompactLogix and MicroLogix 1500 controllers used. Using the same modules or any combination can maximize the number of supported modules, however, power distance ratings must be observed. For CompactLogix, no instance of the module should be more than 8 modules away from the power supply.

Allen-Bradley's 1769-IF4XOF2 compact 8-bit low-resolution analog I/O module is an I/O module with four (4) analog input points and two (2) analog output points. It has four single-ended analog inputs with a maximum operating voltage range of 0 to 10.5 volts DC and a current range of 0 to 21 mA. It uses the successive approximation converter type and has a maximum resolution of 8 bit plus symbol and a response speed of 5 ms per channel. It has an operating voltage of 30 volts AC /30 volts DC, a common mode voltage (CMD) of 10 volts DC per channel, and a common mode rejection of 60db at 1 volt between 60 Hz and the input. The 1769-IF4XOF2 has a nominal input impedance of 150 kΩ on the voltage end and 150 Ω on the current end.
