Allen-Bradley 1756-IF16 是一款 ControlLogix 模拟输入模块。该模块接受电流和电压信号,例如±10V、0-10V、0-5V和0-20 mA。该模块支持三 (3) 种类型的信号接线配置,例如单端、差分和高速差分接线。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。为了增加噪声敏感性,使用差分接线方法,而在需要相对于输入信号快速更新数据的系统中使用高速差分布线。

通过单端布线,该模块成为十六 (16) 通道模拟输入模块。同样,当与差分接线一起使用时,该模块减少为八(8)通道模拟输入模块。此外,当模块作为高速差分接线接线时,该模块成为四(4)通道模拟输入模块。

1756-IF16 独立分辨率为 320 μV/计数(15 位 + 符号双极性)@ ±10.25V 输入范围;160 μV/计数 (16 位) @ 0-10.25V 输入范围;80 μV/计数(16 位)@ 0-5.125V 输入范围和 0.32 μA/计数(16 位)@ 0-20.5 mA。该模块的扫描时间各不相同,例如单端扫描时间为16-488 ms;8-244 ms(差分接线)和 5-122 ms(高速差分接线)。它具有使用Σ-Δ方法的内置模数转换器电路。转换后的数据按照整数模式(左对齐,2 秒补码)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%。

Through single ended wiring, this module becomes a sixteen (16) channel analog input module. Similarly, when used with differential wiring, this module is reduced to an eight (8) channel analog input module. In addition, when the module is wired as a high-speed differential connection, it becomes a four (4) channel analog input module.
1756-IF16 with independent resolution of 320 μ V/Count (15 bits+symbol bipolar) @ ± 10.25V input range; one hundred and sixty μ V/Count (16 bits) @ 0-10.25V input range; eighty μ V/Count (16 bits) @ 0-5.125V input range and 0.32 μ A/Count (16 bits) @ 0-20.5 mA. The scanning time of this module varies, for example, the single end scanning time is 16-488 ms; 8-244 ms (differential connection) and 5-122 ms (high-speed differential connection). It has the ability to use Σ-Δ The built-in analog-to-digital converter circuit of the method. The converted data is stored in IEEE 32-bit floating-point data format in integer mode (left aligned, 2-second complement). The calibration accuracy of this module is better than 0.05% of the voltage input range and 0.15% of the current input range.
