1756-HSC 计数器模块  执行高速计数

【产品详情】

Allen-Bradley 1756-HSC 是一种计数器模块，用于在工业应用中执行高速计数。该模块具有可选模式，例如频率模式或用于处理输入信号的计数器模式。计数器模式设置为默认模式，可以每 2 毫秒更新一次数据。用户可以更改计数值的存储，因为 1756-HSC 模块使用用户配置的预设来根据计数值对其进行评估。与在控制器中进行评估时相比，这为模块激活输出提供了更快的响应时间。预装的配置标签随 1756- HSC 模块提供，这些标签将决定计数的脉冲是累积计数（范围为 1 到 1600 万），还是正频率或负频率，具体取决于旋转方向。

1756-HSC 模块每个计数器有 3 个输入（A、B 和 Z 用于栅极复位）和 4 个输出（每组 2 个点），每个模块都有可用。最大输入频率在计数器模式（A 输入）下为 1 兆赫兹，在速率测量模式（A 输入）下为 500 千赫兹，在编码器模式下为 250 千赫兹（A/B 输入，X1 或 X4）和 70 赫兹（启用滤波器）。此外，每个计数器通道可以分配任意数量的输出通道，每个输出具有多达 2 个关断预设值。1756-HSC 模块上的输出可以由用户自行决定打开或关闭。5 V 工作时的工作电压范围为 4.5 至 5.5 V DC，12/24 V 工作时的工作电压范围为 10 至 31.2 V DC，总背板功耗为 1.9 W，60 摄氏度时的最大功耗为 5.6 W。1756-HSC 模块通常与 Allen-Bradley 845 增量编码器、PHOTOSWITCH 系列 10,000 光电传感器和 Allen-Bradley Bulletin 872 3 线直流接近传感器一起使用。

Allen-Bradley 1756-HSC 是属于 1756 ControlLogix 产品系列的高速计数器模块。该模块用于计数应用和检测旋转设备（如电机）的位置或旋转程度。

该模块能够与编码器和脉冲发生设备一起使用，例如用于流量累加的计量设备和磁性拾取传感器，以检测设备的转速。

该模块具有内置的计数器和频率模式。所选模式决定了脉冲的计数和存储方式，包括输出行为。

【英文介绍】

The Allen-Bradley 1756-HSC is a counter module designed to perform high-speed counting in industrial applications. The module has optional modes, such as a frequency mode or a counter mode for processing input signals. The counter mode is set to the default mode and the data can be updated every 2 milliseconds. Users can change the storage of the count value because the 1756-HSC module uses user-configured presets to evaluate it against the count value. This provides a faster response time for module activation output compared to when evaluated in the controller. Pre-installed configuration labels are supplied with the 1756-HSC module, and these labels will determine whether the counted pulses are cumulative counts (ranging from 1 to 16 million), or positive or negative frequencies, depending on the direction of rotation.

The 1756-HSC module has 3 inputs per counter (A, B, and Z for gate reset) and 4 outputs (2 points per set), available in each module. The maximum input frequency is 1 MHZ in counter mode (A input), 500 KHZ in rate measurement mode (A input), 250 KHZ in encoder mode (A/B input, X1 or X4) and 70 Hz (filter enabled). In addition, each counter channel can be assigned any number of output channels with up to 2 off presets per output. The output on the 1756-HSC module can be turned on or off at the user's discretion. The operating voltage range is 4.5 to 5.5 V DC at 5 V and 10 to 31.2V DC at 12/24 V, with a total backplane power consumption of 1.9W and a maximum power consumption of 5.6W at 60 ° C. The 1756-HSC module is typically used with the Allen-Bradley 845 incremental encoder, the PHOTOSWITCH Series 10,000 photoelectric sensor, and the Allen-Bradley Bulletin 872 3-wire DC proximity sensor.

The Allen-Bradley 1756-HSC is a high-speed counter module belonging to the 1756 ControlLogix product family. The module is used for counting applications and detecting the position or degree of rotation of rotating equipment such as motors.

The module can be used with encoders and pulse-generating devices, such as metering devices for flow accumulation and magnetic pickup sensors to detect the rotational speed of the device.

The module has a built-in counter and frequency mode. The selected mode determines how the pulses are counted and stored, including the output behavior.
