FT232RL/CH343G USB TO RS232/485/TTL Interface Converter, Industrial Isolation

Industrial Grade Isolated USB Converter

USB TO RS232/485/TTL

Stable transmission | Multiple devices applicable | Multi-OS compatible

Features At A Glance

Adopt original FT232RL or 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 proof performance
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

Original Industrial Grade Chip

Onboard original FT232 or CH343 chip
Fast communication, stable & reliable, better compatibility

Safer Isolated Design

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

Multi-protocol & Multi-type Conversion

USB TO RS232, RS485 or TTL(UART)

RS232, RS485 or TTL(UART) TO USB

* only one of the RS232, RS485, and TTL can be converted to USB at the same time; And RS232, RS485, and TTL cannot be converted between each other

Multiple Protection, Safe And Stable

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 proof performance.

Multi system Support

Supports Mac, Linux, Android, Windows 11 / 10 / 8.1 / 8 / 7, etc.
