Description:

The Waveshare Industrial USB to 4-Channel RS485 Converter is a high-performance communication interface designed for reliable and robust industrial data transmission. Featuring four independent RS-485 channels, this converter supports simultaneous multi-device communication across various systems.

Built with multiple protection circuits—including ESD, surge, and over-voltage protection—it ensures stable operation in harsh environments. The durable aluminum alloy casing enhances heat dissipation and provides long-term durability, while wall-mount and DIN rail-mount support offer flexible installation options. Compatible with major operating systems, it’s ideal for industrial automation, data acquisition, and control systems.
