Allen-Bradley 1756-IF6I 隔离式模拟电压/电流输入模块

【产品详情】

Allen-Bradley 1756-IF6I是一款隔离式模拟电压/电流输入模块。它有六 （6） 个独立隔离的输入，是 ControlLogix 系统的一部分。该模块需要 20 针 1756-TBNH 或 1756-TBSH 可拆卸接线端子 （RTB），然后才能连接输入信号。您可以在 1756-IF6I 的两种数据格式之间进行选择：整数模式和浮点模式。它有 16 个有效位，您可以在一系列操作范围中选择用于模块上每个通道的范围。可用范围及其各自的分辨率如下： +/- 10.5 伏有 343 ？伏特/计数，0 至 10.5V 有 171 ？伏特/计数，0 到 5.25 伏有 86 ？伏特/计数，0 到 21 毫安有 0.34 ？A/计数。当隔离输入模块的工作超出输入范围设置的限制时，将激活欠量程/超量程检测功能。使用模块的模数转换器可以消除应用中每个通道的线路噪声。由于每个滤波时间都会影响模块的响应时间和最高频率陷波滤波器设置，因此请限制通道的有效分辨率。请记住选择与预期噪声频率最接近的陷波滤波器。此外，该器件还集成了一个数字滤波器，可平滑每个输入通道上的输入数据噪声瞬变。

实时采样（RTS）是1756-IF6I的另一个特点。配置模块时，需要设置请求的数据包间隔 （RPI） 周期和实时采样 （RTS） 周期。设置这些参数后，模块将扫描其输入通道并收集所有可用数据，扫描后，模块将对数据进行多播。它还具有断线检测功能，当电线与通道断开或RTB从模块中移除时，该功能会触发。此外，1756-IF6I 还配备了速率报警功能，适用于使用浮点模式的应用。这将监控输入样本之间的变化率。每个通道超过该通道的指定触发点都会产生警报。过程警报也存在，当模块超过每个通道的配置上限或下限时触发。

Allen-Bradley 1756-IF6I 是一款 ControlLogix 模拟量输入模块。该模块有六 （6） 个独立隔离的模拟输入通道。该模块设计用于接收 ±10.5V、0 -10.5V、0-5.25V 和 0-21 mA，分辨率为 16 位。每个通道都内置了输入信号质量检测功能，用于监控和参考信号质量的控制。

对于 +/- 10VDC 输入，最小用户数为 10.54688V，最大用户数为 10.54688V。同样，0-10VDC输入具有0V-10.54688V;0-5VDC有0V-5.27344V;对于0-20mA有0mA-21.09376V。这些输入信号范围由模拟输入通过集成模数转换器通过Sigma-Δ转换方法进行转换。每个输入信号的实际分辨率为 343 ？V/bit for 10.5VDC， 171 ？0-10.5VDC时V/bit;86 ?0 至 5.25V 和 0.34 ？0-21mA的A/bit。

【英文介绍】

The Allen-Bradley 1756-IF6I is an isolated analog voltage/current input module. It has six (6) independently isolated inputs and is part of the ControlLogix system. The module requires a 20-pin 1756-TBNH or 1756-TBSH detachable terminal (RTB) before it can connect to the input signal. You can choose between the two data formats of 1756-IF6I: integer mode and floating point mode. It has 16 significant bits, and you can choose the range for each channel on the module from a range of operations. The available ranges and their respective resolutions are as follows: +/- 10.5 volts has 343? Volts/count, 0 to 10.5V has 171? Volts/count, 0 to 5.25 volts is 86? Volts per count, 0 to 21 mA is 0.34? A/ Count. The underrange/overrange detection function is activated when the work of the isolated input module exceeds the limits set by the input range. The use of modular analog-to-digital converters can eliminate line noise for each channel in the application. Since each filter time affects the module's response time and the highest frequency notch filter Settings, limit the effective resolution of the channel. Remember to select the notch filter that is closest to the expected noise frequency. In addition, the device incorporates a digital filter that smooths the noise transients of the input data on each input channel.

Real-time sampling (RTS) is another feature of the 1756-IF6I. When configuring a module, you need to set the requested Packet interval (RPI) period and real-time sampling (RTS) period. After setting these parameters, the module will scan its input channels and collect all available data, after scanning, the module will multicast the data. It also has a break detection function, which is triggered when the wire is disconnected from the channel or the RTB is removed from the module. In addition, the 1756-IF6I is equipped with a rate alarm function for applications using floating-point mode. This will monitor the rate of change between input samples. Each channel that exceeds the specified trigger point for that channel generates an alert. Process alerts also exist, triggered when a module exceeds the upper or lower limit of the configuration for each channel.

The Allen-Bradley 1756-IF6I is a ControlLogix analog input module. The module has six (6) independently isolated analog input channels. The module is designed to receive ±10.5V, 0-10.5V, 0-5.25V and 0-21 mA with a 16-bit resolution. Each channel has a built-in input signal quality detection function for monitoring and reference signal quality control.

For +/ -10VDC input, the minimum number of users is 10.54688V, and the maximum number of users is 10.54688V. Similarly, the 0-10VDC input has 0V-10.54688V; 0 to 5VDC: 0V to 5.27344V; For 0-20mA there is 0mA-21.09376V. These input signal ranges are converted from analog inputs via an integrated analog-to-digital converter via the Sigma-Δ conversion method. The actual resolution of each input signal is 343. V/bit for 10.5VDC, 171? 0-10.5VDC V/bit; 86? 0 to 5.25V and 0.34? 0 to 21mA A/bit.
