USB TO RS232/485/TTL Interface Converter, Industrial IsolationIndustrial Grade Isolated USB Converter

Features

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 terminal
Onboard 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 protection
Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
Fully 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 switch
Aluminium 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
