AB产品1756-IF16罗克韦尔全新原装现货模块

Allen-Bradley 1756-IF16是一个ControlLogix模拟输入模块。该模块接受电流和电压信号，如10V、0-10V、0-5V和0-20 mA。该模块支持三(3)种类型的信号布线配置，如单端、差分和高速差分布线。

在支持的布线配置中，单端布线对噪声最敏感，必须与具有公共接地的信号一起使用。为了提高噪声敏感度，使用差分布线方法，而高速差分布线用于需要相对于输入信号快速更新数据的系统。

使用单端接线，模块成为十六(16)通道模拟输入模块。类似地，当使用差分接线时，该模块被简化为八(8)通道模拟输入模块。此外，当模块作为高速差分接线时，模块成为四(4)通道模拟输入模块。

1756-IF16单个分辨率为320V/计数(15位+符号双极性)@ 10.25V输入范围；160V/计数(16位)@ 0-10.25V输入范围；在0-5.125V输入范围时每计数80V(16位)，在0-20.5 mA时每计数0.32 A(16位)。

该模块具有变化的扫描时间，例如单端的16-488 ms；使用差分布线时为8-244毫秒，使用高速差分布线时为5-122毫秒。它内置一个采用适马-德尔塔法的模数转换器电路。转换后的数据按照整数模式(左对齐，2 s补码)IEEE 32位浮点数据格式存储。该模块的校准精度优于电压输入范围的0.05%和电流输入范围的0.15%。

Allen-Bradley 1756-IF16 is a ControlLogix analog input module. The module accepts current and voltage signals such as 10V, 0-10V, 0-5V and 0-20 mA. The module supports three (3) types of signal routing configurations such as single-ended, differential, and high-speed differential routing.

Of the supported wiring configurations, single-ended wiring is the most sensitive to noise and must be used with signals with common ground. In order to improve noise sensitivity, differential wiring methods are used, while high-speed differential wiring is used in systems where data needs to be updated quickly relative to the input signal.

Using single-ended wiring, the module becomes a sixteen (16) channel analog input module. Similarly, when using differential wiring, the module is reduced to an eight (8) channel analog input module. In addition, when the module is wired as a high-speed differential, the module becomes a four (4) channel analog input module.

1756-IF16 Single resolution 320V/ count (15-bit + sign bipolar)@ 10.25V input range; 160V/ Count (16 bits) @0-10.25V input range; 80V(16 bits) per count at 0-5.125V input range, 0.32A (16 bits) per count at 0-20.5mA.

The module has variable scan times, such as 16-488 ms single-ended; 8-244 ms when using differential wiring and 5-122 ms when using high-speed differential wiring. It has a built-in analog-to-digital converter circuit using the Sigma Delta method. The converted data is stored in integer mode (left justified, 2 s complement)IEEE 32-bit floating-point data format. The module's calibration accuracy is better than 0.05% of the voltage input range and 0.15% of the current input range.
