ZYT-82 RS-232 isolator is a serial optical isolator produced by Guangzhou Zhiyuan Electronic Co., Ltd. It adopts the unique serial port power theft and optical isolation technology, which can effectively protect RS-232 serial port devices, avoid ground loop voltage, surge, induced lightning strike, static electricity, hot plug and other harsh environments damage to the device.
The ZYT-82 RS-232 isolator protects RS‑232 interfaces from ground loops, electro‑static discharge, surge, and electromagnetic interference. It offers up to 4000 V (short‑term) isolation and supports full‑duplex communication.
Key specifications include compliance with EIA RS‑232, a baud‑rate range of 0‑57600 bps, operating temperature 0‑50 °C, and a weight of about 50 g. The device uses DB9 connectors with defined pin assignments and requires an external power source (TXD, RTS or DTR). Technical support contact information is provided at the end of the manual. This manual is written in Chinese.
