Two pieces USB to RS485 isolated converter modules. Each module uses a CH340E USBtoserial bridge, provides galvanic isolation and industrial ESD protection, and uses a standard RS485 connector board. This package is designed to upgrade RS485 communication reliability in challenging environments. Key benefits Galvanic isolation protects the host computer and RS485 devices from voltage surges and ground loops, improving reliability in harsh or longdistance installations. Industrial ESD protection helps guard the interface against static discharge and transient disturbances common in industrial settings. CH340E USBtoserial bridge delivers a stable, USBconnected RS485 interface for dependable data transmission. Standard RS485 connector board compatibility simplifies integration with existing RS485 cables and devices. Two modules per package enable dualchannel use, testing, or redundancy for critical applications. Compact form factor and robust design suited for panel mounting or enclosure integration. Key attributes Functionality: USB to RS485 isolated converter module with CH340E driver bridge and ESD protection. Compatibility: Standard RS485 interface with USB host connection; suitable for integration into industrial networks and equipment that use RS485 communications. Size: Compact module design optimized for easy installation in equipment enclosures or on a desktop test setup. Material and construction: Built on a robust PCB with industrialgrade components and reliable connectors to withstand daily use in industrial environments.
