Passive RS232 to RS422 FDX FullDuplex Serial Converter Adapter, Bidirectional RS232RS422 Signal Switch No External Power Required, Compact Serial Adapter for PLC, Industrial Instrument Controller Fi

This passive RS232RS422 fullduplex serial converter performs bidirectional level conversion between RS232 and RS422 serial interfaces. It requires no external power supply, extracting operating power from existing serial signal lines to cut extra wiring work for onsite deployment. Adopting FDX fullduplex architecture, it supports simultaneous transmit and receive data without communication latency loss. RS422 differential signal brings longer cable reach and stronger immunity against electromagnetic interference compared with ordinary RS232, wellsuited for industrial control PLC, measuring instruments, accesscontrol devices and remote serial debugging scenarios. Compact plugin form enables fast installation, no firmware adjustment or software setup required. Since it is a passive module, reliable communication relies on sufficient signal voltage output from your connected host devices. Serial cables are not included in package. Do not feed highvoltage signals into this adapter to prevent permanent circuit burnout.
