Waveshare CH343G USB to RS232/485/TTL Interface Industrial Isolated Converter Protection Circuits and Aluminium Alloy Enclosure for Industrial Control Equipments

Adopt original CH343G inside fast communicating stable and reliable better compatibility. Onboard unibody power supply isolation provides stable isolated voltage needs no extra power supply for the isolated terminalOnboard unibody digital isolation allows signal isolation high reliability strong anti-interference low power consumption. Onboard TVS (Transient Voltage Suppressor) effectively suppress surge voltage and transient spike voltage in the circuit lightningproof & ESD protectionOnboard self-recovery fuse and protection diodes ensures the current/voltage stable outputs provides over-current/over-voltage proof improves shock resistanceFully automatic transceiver circuit with no delay ensures the USB port communicates with different interfaces fastly and stably without interfering each other.

Onboard TTL serial 3.3V /5V voltage translator config the TTL level via switchAluminium alloy enclosure with sand blasting and anodic oxidation CNC process opening solid and durable. 3 LEDs for indicating the power and transceiver status. High quality USB-B and RS232 connectors smoothly plug/pull
