YR-8005, Communication Isolation Repeater, is a device used for signal isolation, conversion, and transmission. It converts RS-232 to RS-485 for signal amplification and isolation, thereby achieving long-distance data transmission and preventing interference. This equipment is suitable for industrial automation control, security monitoring and other fields, and can improve system stability and reliability. Each repeater can connect 32 RS-485 interface devices from point to multipoint, with a data communication rate of 300-115200bps. The internal power indicator and data flow indicator light can indicate the fault situation. Introducing intelligent isolation mechanism, real-time detection of data features, judgment of bus status, automatic isolation of faulty buses and provision of fault indications, ensuring the normal operation of other ports, providing great convenience for engineering and technical personnel in installation and maintenance. This product adopts a modular design and can be combined for use. It is installed with a standard 35mm DIN rail, with detachable terminals, small size, and light weight, which can save a lot of space and time for on-site installation.

When using communication isolation relays, the following precautions should be taken:

1. Confirm the correct connection between the isolator and the equipment;

2. Ensure that the power supply voltage meets the requirements of the isolator;

3. Avoid excessively high signal amplitude to avoid affecting the isolation effect;

4. Select appropriate baud rate and data format to ensure stable communication;

5. Prevent environmental factors such as static interference and lightning strikes from affecting the equipment;

6. Regularly check the working status of the isolator to ensure its normal operation.
