OneOverview of OPC420 fiber optic converter
OPC420 optical fiber converter is a kind of industrial grade optical fiber communication equipment designed by YINHE ELECTRIC Co., Ltd., which is specially designed to solve the analog signal transmission of 4-20mA under complex electromagnetic environment. Using the device can effectively solve the complex electromagnetic environment (such as the extensive use of inverter, transformer, rectifier and other nonlinear devices in industrial field) electromagnetic interference, ring interference and lightning damage such as signal transmission problems caused by EMI, effectively improve the measurement accuracy, reliability and safety of equipment operation.
4-20mA is the most commonly used analog signal in industrial field, because it is a direct current signal transmission, so it has strong anti-interference ability, good compatibility and interchangeability. However, with the increasing complexity of the electromagnetic environment, the limitations of the anti-jamming are more and more serious.
OPC420 optical fiber converter to achieve 4-20mA standard between analog signals and digital signal transmission in optical fiber mutual conversion, usually paired with OPC420/A, 4-20mA, 0-20mA optical fiber converter or 0-5V analog signal into digital signal, through the optical fiber transmission to the measuring instrument end by OPC420/B optical fiber converter converts the digital signal optical fiber transmission 4-20mA standard analog signal is transmitted to the measuring instrument.
Chart 1 OPC420 optical fiber converter will achieve digital optical fiber transmission instead of 4-20mA analog transmission
Using a pair of fiber OPC420 converter can be realized by optical fiber as the transmission medium of the 4-20mA conversion of analog and digital cable, effectively cut off the interference transmission signal in the transmission process, improves the electromagnetic compatibility of equipment. The electromagnetic compatibility of the system is improved on the basis of not changing the other aspects of the system.
