RS485 Repeater Anti‑Thunder Optoelectronic Isolation High‑Speed Transmission Hub for Expand Transmission Distance

Feature: 1. YN2209 is an active isolated RS‑485 repeater designed to solve the industrial complex electromagnetic environment. The external power supply can ensure the stability and reliability of the equipment during long‑term operation. 2. Photoelectric technology isolation can ensure that the equipment is not damaged by the ground loop and the common mode voltage difference during the communication process. 3. YN2209 can extend the existing RS485 by 1200m to solve the problem of signal attenuation caused by too long RS485 wiring. The baud rate supported at the same time is up to 115.2kpbs. 4. The direction control of the RS‑485 bus is automatically completed by the on‑board microprocessor, without software intervention, and the YN2209 can work in an industrial‑grade temperature and humidity environment 5. Can be used for video surveillance, building intercom, PLC, card access control, power acquisition, time attendance, etc. Specification: Item Type: RS485 Repeater Material: ABS Model: YN2209 1.
