I、 Product Introduction:The YT-5208 single mode fiber optic to 8-port RS485 hub has strong anti-interference ability and long transmission distance, making it the first choice for large-scale 485 engineering projects. This product breaks through the contradiction between traditional RS-232/422/485 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. It can be widely used in various industrial control, process control, traffic control, and other occasions, especially suitable for banks, power plants, and departments and systems with special requirements for electromagnetic interference environments.
Application fields: military control, industrial automation control, traffic control, video control, distributed data acquisition system, power acquisition and control system, intelligent community, highway toll system, etc.
II、 Product features:1. RS485 signal fiber optic transmitter and 8-way RS485 hub in one product
1. Transmission rate: 300-115.2Kbps adaptive
2. Transmission distance: 2M for multimode fiber and 20KM for single mode fiber
3. Optical connector: FC/SC/ST optional, single/dual fiber optional, default to single mode fiber
4. Interface terminal: standard industrial crimping terminal
5. Both data input and output have LED signal indicator lights
6. Can construct network topology structures such as stars and chains
7. Fully transparent communication, users do not need any debugging, plug and play
8. Integrated pure hardware optical fiber transceiver module, zero delay of transmission signal, stable and reliable output optical power of Optical module. (Many similar Optical module on the market are soft decompressed, and the signal has obvious delay, which will cause incompatibility with some devices)
9. The RS485 output terminal is equipped with a 1200w lightning protection TVS tube at each port, which can quickly suppress lightning strikes and static damage. The terminal can be equipped with electric heating plug. Combined with fiber optic transmission, the overall reliability of the product has been greatly improved.
10. The input and output ends of the hub are completely insulated, resistant to electromagnetic interference, ground ring interference, and lightning damage
11. All surface mount processes, industrial grade design, SMT machine assembly line production
III、 Product List:1. 1 optical fiber to 8-way RS485 hub
2. 1 standard 12V/500mA power supply
3. 1 instruction manual
