>>>>>型號(hào):1756-IF16 模擬量輸入模塊 該模塊接受電流和電壓信號(hào)
【功能描述】
Allen-Bradley 1756-IF16 是一款 ControlLogix 模擬量輸入模塊。該模塊接受電流和電壓信號(hào)，例如 ±10V、0-10V、0-5V 和 0-20 mA。該模塊支持三 （3） 種類型的信號(hào)接線配置，例如單端、差分和高速差分接線。在支持的接線配置中，單端接線對(duì)噪聲最敏感，必須與具有公共接地的信號(hào)一起使用。為了提高噪聲敏感性，在需要相對(duì)于輸入信號(hào)快速更新數(shù)據(jù)的系統(tǒng)中使用差分布線方法，而高速差分布線則使用差分布線。
通過(guò)單端接線，該模塊成為十六 （16） 通道模擬輸入模塊。同樣，當(dāng)與差分接線一起使用時(shí)，該模塊被簡(jiǎn)化為八 （8） 通道模擬輸入模塊。此外，當(dāng)模塊作為高速差分接線接線連接時(shí)，該模塊將成為四 （4） 通道模擬輸入模塊。
1756-IF16 的單個(gè)分辨率為 320 μV/計(jì)數(shù)（15 位 + 符號(hào)雙極性）@ ±10.25V 輸入范圍;160 μV/計(jì)數(shù)（16 位）@ 0-10.25V 輸入范圍;80 μV/計(jì)數(shù)（16 位）@ 0-5.125V 輸入范圍和 0.32 μA/計(jì)數(shù)（16 位）@ 0-20.5 mA。該模塊的掃描時(shí)間各不相同，例如單端為 16-488 毫秒;8-244 ms（差分接線）和 5-122 ms（高速差分接線）。它具有使用 Sigma-Delta 方法的內(nèi)置模數(shù)轉(zhuǎn)換器電路。轉(zhuǎn)換后的數(shù)據(jù)按照整數(shù)模式（左對(duì)齊，2 秒補(bǔ)碼）IEEE 32 位浮點(diǎn)數(shù)據(jù)格式存儲(chǔ)。該模塊的校準(zhǔn)精度優(yōu)于電壓輸入量程的 0.05% 和電流輸入量程的 0.15%。

【英文介紹】
The 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 wiring configurations, such as single-ended, differential, and high-speed differential wiring. Of the supported wiring configurations, single-ended wiring is the most sensitive to noise and must be used with a signal with common ground. In order to improve noise sensitivity, differential wiring methods are used in systems where data needs to be updated quickly relative to the input signal, while high-speed differential wiring uses differential wiring.
With single-ended wiring, the module becomes a sixteen (16) channel analog input module. Again, when used with differential wiring, the module is reduced to an eight (8) channel analog input module. In addition, when the module is connected as a high-speed differential wiring, the module will become a four (4) channel analog input module.
The 1756-IF16 has a single resolution of 320 μV/ count (15-bit + sign bipolar) @ ±10.25V input range; 160 μV/ Count (16 bits) @ 0-10.25V input range; 80 μV/ Count (16-bit) @ 0-5.125V Input range and 0.32 μA/ count (16-bit) @ 0-20.5 mA. The scanning time of the module varies, for example 16-488 milliseconds for a single end; 8-244 ms (differential connection) and 5-122 ms (high-speed differential connection). 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-second 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.
