The WVS RS-232/F to RS422/RS485 Converter is an industrial-grade, active, digitally isolated communication interface converter designed to enable reliable data transmission between RS232 devices and RS422/RS485 networks. It features full electrical isolation, surge protection, and zero-delay automatic data direction control for stable long-distance communication in demanding environments.
Detailed Description
This converter is built for industrial communication systems requiring robust noise immunity, long-distance transmission, and high reliability. It integrates onboard SP3232EEN and SP485EEN chips, ensuring stable and compatible signal conversion across multiple serial communication standards.
The device includes both power and signal isolation using integrated digital and magnetic isolation technology, preventing ground loops and improving system safety. Built-in TVS surge protection, ESD protection up to 15KV, and lightning suppression up to 600W protect against electrical transients and harsh industrial conditions.
With support for baud rates from 300 to 921600bps, it allows flexible integration into a wide range of systems, from legacy equipment to modern automation networks. RS485/RS422 communication supports distances up to 1.2km and multi-node configurations (up to 32 nodes), making it ideal for distributed control systems.
The rail-mount ABS enclosure allows easy DIN-rail installation, while onboard LED indicators provide real-time status monitoring of power and data transmission. A wide 5-36V DC input range with reverse polarity protection ensures flexible and safe power integration.
