FOXBORO FBI10E特點(diǎn):
FOXBORO FBI10E 現(xiàn)場(chǎng)總線隔離器，用于在工業(yè)環(huán)境中隔離和保護(hù)現(xiàn)場(chǎng)總線網(wǎng)絡(luò)

隔離器是一種采用線性光耦隔離原理的設(shè)備，用于將輸入信號(hào)進(jìn)行轉(zhuǎn)換輸出。其特點(diǎn)在于輸入、輸出和工作電源三者相互隔離，特別適合與需要電隔離的設(shè)備儀表配用。隔離器又名信號(hào)隔離器，是工業(yè)控制系統(tǒng)中重要的組成部分。
在工業(yè)生產(chǎn)過(guò)程中，F(xiàn)OXBORO FBI10E 實(shí)現(xiàn)監(jiān)視和控制需要使用各種自動(dòng)化儀表、控制系統(tǒng)和執(zhí)行機(jī)構(gòu)，它們之間的信號(hào)傳輸既包含微弱到毫伏級(jí)、微安級(jí)的小信號(hào)，也有幾十伏，甚至數(shù)千伏、數(shù)百安培的大信號(hào)，既有低頻直流信號(hào)，也有高頻脈沖信號(hào)等。由于這些信號(hào)的復(fù)雜性，儀表和設(shè)備之間的信號(hào)傳輸可能會(huì)互相干擾，導(dǎo)致系統(tǒng)不穩(wěn)定甚至誤操作。其中，一個(gè)重要的因素是由于儀表和設(shè)備之間的信號(hào)參考點(diǎn)之間存在電勢(shì)差，形成“接地環(huán)路”，造成信號(hào)傳輸過(guò)程中失真。隔離器的作用就在于斷開(kāi)過(guò)程環(huán)路，同時(shí)又不影響過(guò)程信號(hào)的正常傳輸，從而解決接地環(huán)路問(wèn)題。

FOXBORO FBI10E Features:
The FOXBORO FBI10E Fieldbus isolator is used to isolate and protect fieldbus networks in industrial environments
Prevents electrical noise and interference and is compatible with a wide range of fieldbus protocols.
Compact structure, easy to install, wide range of applications,
Isolator is a device that uses the principle of linear optocoupler isolation to convert the input signal to the output. Its characteristic is that the input, output and working power supply are isolated from each other, especially suitable for use with equipment and meters that need electrical isolation. The isolator, also known as the signal isolator, is an important part of the industrial control system.
In the industrial production process, FOXBORO FBI10E to achieve monitoring and control requires the use of a variety of automated instruments, control systems and actuators, the signal transmission between them contains both weak to millivolt level, microampere level of small signals, there are tens of volts, even thousands of volts, hundreds of amperes of large signals, both low-frequency DC signals, but also high-frequency pulse signals. Due to the complexity of these signals, signal transmission between instruments and devices may interfere with each other, leading to system instability and even misoperation. Among them, an important factor is that there is a potential difference between the signal reference points between the instrument and the device, forming a "ground loop", resulting in distortion during signal transmission. The role of the isolator is to disconnect the process loop without affecting the normal transmission of the process signal, so as to solve the ground loop problem.
