1746-NI8 模拟单槽I/O模块

Allen-Bradley 1746-NI8是SLC 500系统的模拟单槽I/O模块。它适用于需要快速模拟信号转换和高精度的时间敏感应用。1746-NI8模块具有8通道输入和隔离背板。在5伏直流电和24伏直流电下,背板电流消耗分别为200mA和100mA。它的最大背板功耗在5伏直流时为1瓦,在24伏直流时为2.4瓦。1746-NI8可以安装在SLC 500 I/O机箱除0号槽位外的任何I/O槽位上。输入信号数据通过逐次逼近转换转换为数字数据。1746-NI8模块使用可编程滤波器频率和低通数字滤波器进行输入滤波。它执行连续自动校准,隔离电压为750伏直流和530伏交流,测试60秒。它的共模电压范围为-10 ~ 10伏,任意两个端子之间的最大共模电压为15伏。

1746-NI8模块配有18个位置的可拆卸端子块。对于布线,必须使用Belden 8761或类似的电缆,每个终端有一根或两根14awg线。电缆在电压源处的最大回路阻抗为40欧姆,在电流源处的最大回路阻抗为250欧姆。有9个绿色LED状态指示灯,用于故障处理和诊断。8个通道各有一个显示输入状态的指示灯,各有一个显示模块状态的指示灯。1746-NI8具有二级危险环境标准,工作温度为0至60摄氏度。

1746-NI8具有八(8)通道模拟输入模块,适用于SLC 500固定或模块化硬件风格控制器。该模块来自Allen-Bradley,具有单独可选的电压或电流输入通道。可供选择的输入信号包括:电压为10V dc, 1-5V dc, 0-5V dc, 0-10V dc,电流为0 – 20ma, 4 – 20ma, +/- 20ma。

输入信号可以表示为工程单位,pid缩放,比例计数(-32,768至+32,767范围),用户定义范围的比例计数(仅限3类)和1746-NI4数据。

这个八(8)通道模块兼容使用SLC 5/01, SLC 5/02, SLC 5/03, SLC 5/04和SLC 5/05处理器。SLC 5/01只能作为1级操作,而SLC 5/02、5/03、5/04可配置为1级和3级操作。每个模块的通道可以采用单端或差分输入方式布线。

该模块具有可移动的端子块,用于连接输入信号,无需重新布线即可轻松更换模块。输入信号类型的选择是使用嵌入式拨码开关完成的。

1746-NI8 模拟单槽I/O模块

The Allen-Bradley 1746-NI8 is an analog single-slot I/O module for the SLC 500 system. It is suitable for time-sensitive applications that require fast analog signal conversion and high accuracy. The 1746-NI8 module has an 8-Channel input with an isolated backplane. Its backplane current consumption is 200mA and 100mA at 5 Volts DC and 24 Volts DC respectively. It has a maximum backplane power consumption of 1 Watt at 5 Volts DC and 2.4 Watts at 24 Volts DC. The 1746-NI8 can be installed in any I/O slot, except Slot 0 of the SLC 500 I/O chassis. Input signal data is converted to digital data via successive approximation conversion. The 1746-NI8 module uses programmable filter frequencies with a low-pass digital filter for input filtering. It performs continuous autocalibration and has an isolation voltage of 750 Volts DC and 530 Volts AC, tested for 60 seconds. It has a common-mode voltage ranging from -10 to 10 Volts with a maximum of 15 Volts between any two terminals.

The 1746-NI8 module comes with a removable terminal block of 18 positions. For wiring, the Belden 8761 or a similar cable must be used with one or two 14 AWG wires per terminal. The cable has a maximum loop impedance of 40 Ohms at the voltage source and 250 Ohms at the current source. For troubleshooting and diagnostics, it has 9 green LED status indicators. The 8 channels have one indicator each to display the input status and one each for displaying the module status. The 1746-NI8 has a Division 2 hazardous environment standard with an operating temperature of 0 to 60 degrees Celsius.

The 1746-NI8 features Eight (8) channel analog input module compatible for used with SLC 500 Fixed or modular hardware style controllers. This module from Allen-Bradley has individually selectable voltage or current input channels. Available selectable input signals include 10V dc, 1–5V dc, 0–5V dc, 0–10V dc for Voltage while 0–20 mA, 4–20 mA, +/-20 mA for Current.

Input signals may be represented as Engineering Units, Scaled-for-PID, Proportional Counts (–32,768 to +32,767 range), Proportional Counts with User Defined Range (Class 3 only) and 1746-NI4 Data.

This Eight (8) channel module is compatible for use with SLC 5/01, SLC 5/02, SLC 5/03, SLC 5/04 and SLC 5/05 processors. SLC 5/01 may only operate as class 1 while SLC 5/02, 5/03, 5/04 are configurable for Class 1 and Class 3 operation. The channels of each module may be wired in single-ended or differential input.

This module has a removable terminal block for connection to input signals and easy replacement of module without the need of rewiring. Selection of input signal type is done with the use of embedded DIP switches.
