Industrial grade 1-4 RS232/422/485 serial port fiber optic ring network optical transceiver OX-SRDRQ1-4G

Provide 1-4 independent serial ports (RS232/422/485 optional) channels, physically isolated from each other; Provide two fiber optic lines that can automatically switch in case of line failure to ensure normal communication; ? Supports multiple fiber optic network structures: point-to-point, star, chain, ring redundancy, and can be combined into more complex network topologies; The electrical interface is powered by an independent power module, completely isolating the ground circuit between the bus and the device. It also uses optoelectronic isolation technology to isolate internal communication and bus data signals. There are three data interfaces to choose from: RS232/485/422, RS232 supports 3-wire RS232 (TXD, RXD, GND), and supports flow control CD, DSR, CTS; RS232/485/422 channels can transmit asynchronous serial data with adaptive baud rates ranging from 0 to 115200; Serial port interface lightning protection meets IEC61000-4-5 (8/20 μ S) differential mode: 6KV, impedance (2 Ω); Common mode: 6KV, impedance (2 Ω) standard, supports wide range AC/DC input, supports internal isolation, redundant dual power input, power supply supports overload protection and anti reverse protection; ? Complies with industrial level four electromagnetic compatibility requirements; Super lightning protection function: lightning protection, can resist induced high voltage, surge protection, etc; Fanless efficient heat dissipation reduces repair time; IP40 shell protection level, able to withstand the test of harsh environments; ? Rail or wall mounted installation; Wide temperature type: working temperature -40 ℃~85 ℃;

The OX-SRDRQ1-4G industrial grade data ring network optical transceiver provides 1-4 RS232/422/485 channels for transmission over optical fibers, supporting various fiber network topologies such as point-to-point communication, chain network, star network, and redundant ring network self-healing protection. It can also be used to form more complex network topologies and has ring network self-healing protection function. This product breaks through the contradiction between traditional serial interface communication distance and communication speed, and also solves the problems of electromagnetic interference, ground loop interference, and lightning damage, greatly improving the reliability, security, and confidentiality of data communication.
