1756-IB16是羅克韋爾自動(dòng)化生產(chǎn)的ControlLogix離散輸入模塊。
該模塊具有十六個(gè)獨(dú)立隔離的輸入通道，接受10-30VDC的輸入信號(hào)電壓范圍，標(biāo)稱(chēng)值為24VDC。該模塊通常用于連接離散設(shè)備，如按鈕、開(kāi)關(guān)、輔助觸點(diǎn)和其他提供二進(jìn)制或開(kāi)關(guān)信號(hào)狀態(tài)的設(shè)備。1756-IB16是一個(gè)單槽模塊，可安裝到任何1756
ControlLogix機(jī)箱上。1756-IB16I輸入通道具有固有的信號(hào)轉(zhuǎn)換延遲。
輸入模塊是用于接收設(shè)備動(dòng)作信號(hào)的模塊，通常與傳感器、開(kāi)關(guān)、按鈕等設(shè)備配套使用，是實(shí)現(xiàn)自動(dòng)化控制的重要組成部分。
輸入模塊根據(jù)接收信號(hào)的不同，分為單輸入模塊和多輸入模塊。單輸入模塊只接收一個(gè)設(shè)備的動(dòng)作信號(hào)，而多輸入模塊則可以接收多個(gè)設(shè)備的動(dòng)作信號(hào)。
此外，根據(jù)使用場(chǎng)合的不同，輸入模塊可分為離散輸入模塊和模擬輸入模塊。離散輸入模塊接收的是開(kāi)關(guān)量信號(hào)，而模擬輸入模塊接收的是模擬量信號(hào)。

1756-IB16

The 1756-IB16 is a ControlLogix discrete input module manufactured by Rockwell Automation.
The module has sixteen independently isolated input channels that accept input signal voltage ranges from 10-30VDC, with a nominal value of 24VDC. This module is commonly used to connect discrete devices such as buttons, switches, auxiliary contacts, and other devices that provide binary or switching signal states. The 1756-IB16 is a single slot module that can be installed into any 1756
ControlLogix on the chassis. The 1756-IB16I input channel has an inherent signal conversion delay.
The input module is a module used to receive the action signal of the device, which is usually used with sensors, switches, buttons and other devices, and is an important part of realizing automatic control.
The input module is divided into single input module and multi-input module according to the different received signals. The single-input module only receives the action signal of one device, while the multi-input module can receive the action signal of multiple devices.
In addition, according to the different use occasions, the input module can be divided into discrete input module and analog input module. The discrete input module receives the switching signal, while the analog input module receives the analog signal.
