产品详情内容介绍
DO814输出模块
所示逻辑用于从中生成寄存器40020中的标度值3001中的模拟信号。例如：30001=3800；40020=0051华氏度注意：只使用乘法的高阶结果，不进行补偿本例中使用了for四舍五入。校准工具模拟输入模块在出厂前进行校准。为了确保根据模块精度，应每年定期校准微调罐。
校准模拟输入模块需要以下工具和材料：z精度为0.0001 V、电压为10 V的精密数字读数伏特计规模
z一把1/8英寸的薄刃螺丝刀。
z一把1/4英寸十字螺丝刀。
z一种粘合剂（如Loctite或Glyptol），用于固定装饰罐调整螺钉。
校准程序使用下表校准模块。要正确设置模拟输入模块，八位DIP开关必须与位于左侧的五位DIP开关的SW5一起设置单元这些开关确定输入范围、输出格式、要平均化的样本和输入类型。
全体的B875–200可配置A/D输入模块可转换多种信号源
热电偶、RTD、应变计/称重传感器、电压和电流输入范围二进制数据。当为八个通道选择时，模块显示在I/O中地图为B875–200；当为四个通道选择时，它显示在I/O图中作为B873-200。
该模块提供了轮询各种现场设备的能力，需要不同的信号源取决于所选的应用。选择可能是由超过48个可用的输入包组成，每个模块的任何组合可以接受。
注：第三方输入包第三方5B型包装不能保证性能。使用第三方软件包时，请联系制造商寻求支持。八位DIP开关用于根据单元此外，两位跳线用于选择0、2或4个样本每个输入的平均值。平均有助于减少虚假噪声对输入。
一些应用示例包括食品加工、压榨操作、化学加工、涂漆和铸造。
该模块有四/八个模拟输入，能够更新所有八个通道每4毫秒一次。所有范围的12位分辨率和绝对精度取决于输入包类型。这允许快速精确地控制应用注意：此模块需要两个插槽
Calibration Tools
The analog input module is calibrated at the factory prior to shipment. To ensure the module’s accuracy, the trim-pot should be calibrated regularly on a yearly interval. The following tools and materials are needed to calibrate an analog input module: z A precision digital readout voltmeter with an accuracy of 0.0001 V on a 10 V scale. z A 1/8-inch bit, thin-blade screwdriver. z A 1/4-inch Phillips-head screwdriver. z An adhesive (such as Loctite or Glyptol) to secure trim-pot adjustment screws. Calibration Procedure Use the following table to calibrate the module.
The logic shown is used to generate the scaled value in register 40020 from the analog signal in 3001. For example: 30001 = 3800; 40020 = 0051°F NOTE: Only the high-order result of the multiplication is used, and no compensation for round-off is used in this example.To set up the analog input module properly, an eight-position DIP-switch must be set together with SW5 of a five-position DIP switch located on the left side of the module. These switches determines the input range, output format, number of samples to be averaged, and the types of inputs.
General
The B875–200 configurable A/D input module converts a variety of signal sources: thermocouple, RTD, strain gauge/load cell, voltage and current input ranges into binary data. When selected for eight channels, the module is displayed in the I/O map as a B875–200; when selected for four channels, it is displayed in the I/O map as a B873-200. The module provides the capability to poll a wide array of field devices requiring different signal sources based upon the application selected. Selection may be made from more than 48 available input packs, with any mix per module being acceptable. NOTE: Third-party input packs Performance is not guaranteed with third-party 5B type packs. When using thirdparty packs, contact the manufacturer for support. An eight-position DIP switch is used to select from one to eight input channels per module. In addition, a two-position jumper is used to select either 0, 2, or 4 samples to be averaged per input. Averaging helps reduce the impact of spurious noise on the input. Some application examples include food processing, press operating, chemical processing, painting, and foundry casting. The module has four/eight analog inputs and is capable of updates to all eight channels every 4 ms. The 12-bit resolution for all ranges, and the absolute accuracy is dependent on the input pack type. This allows for fast and precise control of the application. NOTE: This module requires two slots
