Introduction
3Wire RS2S2 is a high-performance RS-485 hub designed for use in environments with complex electromagnetic interference. It supports data transmission rates of up to 115.2 kbps.To ensure safe and reliable communication, RS2S2 incorporates optoelectronic isolation technology along with 600W surge protection.
The built-in optoisolator provides up to 2,500V isolation, offering strong protection against lightning surges and ESD.
Features
- External SMPS power supply, which eliminates common ground interference and enhances suitability for outdoor applications.
- Automatic data direction control for RS-485 communication, allowing the device to detect data flow direction and switch accordingly.
- Effectively solves RS-485 communication time delay issues.
