216GD61A HESG324436R3/A HESG324428 光耦合器模塊的輸入側(cè)包括電源或信號輸入電子器件以及LED

光耦合器模塊是一種獨立的DIN導軌安裝器件，為信號路徑提供光學隔離。其核心是一個光耦合器，即一個具有發(fā)光二極管或LED和一個光敏器件的電路。

光耦合器模塊的輸入側(cè)包括電源或信號輸入電子器件以及LED。216GD61A HESG324436R3/A HESG324428 輸出包括輸出電路中的光敏器件（通常是光電晶體管或光電二極管）。當電流通過LED時，它會導致紅外光的發(fā)射，從而激活光敏器件，從而使電流通過光耦合器的輸出。這樣，光耦合器輸出類似于數(shù)字開關(guān)，根據(jù)輸入電壓信號的存在而打開和關(guān)閉。

光耦合器的一個關(guān)鍵參數(shù)是電流傳輸比或CTR，它是輸入和輸出電流之間比率的量度。光耦合器模塊可防止電氣干擾，從簡單的機械限位開關(guān)信號到基于協(xié)議的數(shù)據(jù)傳輸，在工業(yè)環(huán)境中，一切都容易受到電噪聲的影響。如果這些信號必須傳播任何距離，則它們最容易受到攻擊。在這里，光耦合器可以隔離流經(jīng)接地連接的雜散電流產(chǎn)生的共模噪聲。

216GD61A HESG324436R3/A HESG324428 光耦合器模塊的應用范圍廣泛，不僅適用于工業(yè)領(lǐng)域，也適用于通信、測量等領(lǐng)域。其具有高可靠性、高精度和高穩(wěn)定性等優(yōu)點，能夠有效地實現(xiàn)信號的光學隔離和傳輸，提高系統(tǒng)的抗干擾性能和穩(wěn)定性。

The optocoupler module is an independent DIN rail mount that provides optical isolation of the signal path. At its core is a photocoupler, that is, a circuit with a light-emitting diode or LED and a photosensitive device.

The input side of the optocoupler module includes power or signal input electronics as well as leds. 216GD61A HESG324436R3/A HESG324428 Output includes a photosensitive device (usually a phototransistor or photodiode) in the output circuit. When the current passes through the LED, it causes the emission of infrared light, which activates the photosensitive device, thus enabling the current to pass through the output of the optocoupler. In this way, the optocoupler output is similar to a digital switch that turns on and off depending on the presence of the input voltage signal.

A key parameter of the optocoupler is the current transfer ratio, or CTR, which is a measure of the ratio between the input and output currents. Optocoupler modules protect against electrical interference, from simple mechanical limit switch signals to protocol-based data transmission, in industrial environments where everything is susceptible to electrical noise. If these signals have to travel any distance, they are most vulnerable to attack. Here, the optocoupler can isolate common mode noise from stray currents flowing through the ground connection.

The 216GD61A HESG324436R3/A HESG324428 optical coupler module has a wide range of applications, not only for industrial fields, but also for communication, measurement and other fields. It has the advantages of high reliability, high precision and high stability, and can effectively realize the optical isolation and transmission of signals, and improve the anti-interference performance and stability of the system.
