Advantages of electromagnetic coupling isolation
Compared with the traditional optical, magnetic coupling based on magnetic isolation technology has many advantages:
Magnetic coupling and the elimination of the optical coupler of uncertain current transfer ratio, non-linear transfer characteristic and drift with time and with the problem of temperature drift; magnetic coupling are with 25KV/us of common mode transient inhibition ability, and can peak do 560V environment under the normal work in the voltage difference. Magnetic coupling device can provide 5000Vrms/min and 6000V/10sec voltage isolation protection, a variety of models of the magnetic coupling with + ESD 15KV protection.
Using the chip level transformer technology transmission signal, eliminate the transmission loss of device coupler. There is no loss in the device, at least 50 years of working life under normal working conditions.
Magnetic coupling to 150Mbps in under the condition of low power consumption to achieve high-speed data isolation, optocoupler seldom so high transmission rate, to achieve the same high transmission speed, magnetic coupling than the optocoupler has a higher price. Magnetic coupling chip contains the Schmidt circuit, the input and output of the circuit filtering and shaping, and therefore can be directly connected with a variety of high-speed control chip directly, such as: ARM, DSP, PLC, etc..
low power consumption
Magnetic coupling based on the principle of chip level transformer transmission, signal transmission, there is almost no energy loss, so it can be very low power consumption to achieve a high degree of data isolation. The same speed, the power consumption is only 1/10~1/6.
The magnetic isolation technology is realized by using the wafer level process directly on the chip to produce a transformer with a diameter of about 500um. With the unique characteristics of this planar transformer and some innovative circuit design, magnetic isolation products can integrate many different characteristics and functions in one package without affecting the performance. Magnetic coupling standard package: SOIC_W-16, SOIC-8 and SOIC_W-20, etc..
Ease of use
Magnetic coupling of small volume and a variety of channel configuration, the circuit design is more concise, more flexible application. Integrated multi interface transceiver makes the interface isolation circuit more integrated, and the line connection is greatly reduced.
Driver installation and description
RJ-201G1 first need to install the driver in the computer side when using. The system will automatically create a virtual serial port (for example, COM5) when the RJ-201G1 is inserted again. Users only need to be mapped to the virtual serial port can be, and do not need to make any changes to the application software, very convenient. If the virtual serial port number is greater than 7, please use the 1-7, the port will affect the stability of the assembly.
