This Industrial-grade USB to RS485 converter is a robust, bidirectional communication interface designed for reliable data exchange between USB-equipped devices and RS485 networks. Supporting half-duplex transmission, it enables two-way data flow on a single twisted pair line. Engineered with built-in TVS (Transient Voltage Suppression) protection, it safeguards against electrical surges, ESD, and voltage spikes, making it ideal for harsh industrial environments. The unit offers plug-and-play support with most operating systems and features high-speed data transfer up to 3 Mbps, auto-direction control, and strong EMI resistance. Its rugged housing and anti-static design ensure long-term durability and stable signal integrity in field applications.
