Description
Industrial-Grade Isolated USB Converter
USB TO RS232/485/TTL
Stable Transmission | Multi-Device Application | Multi-OS Compatibility
Key Features
- Uses original FT232RNL or CH343G, fast communication, stable and reliable, better compatibility
- Onboard monolithic power isolation, provides stable isolated voltage, no extra power supply required for the isolated terminal
- Onboard monolithic digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge and transient spike voltage in the circuit, lightning proof & anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures stable current/voltage outputs, provides overcurrent/overvoltage protection, improves shock resistance
- Fully automatic transceiver circuit with no delay, ensures the USB port communicates with various interfaces fast and stably without interference
- Onboard TTL serial 3.3V/5V voltage translator, configure the TTL level via switch
- Aluminum alloy enclosure with sandblasting and anodic oxidation, CNC process, solid and durable
- 3 LEDs for indicating power and transceiver status
- High-quality USB-B and RS232 connectors, smooth plug/unplug
