Waveshare USB TO RS232 / RS485 / TTL Industrial Isolated Converter (FT232RL)
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 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
