FT232RNL/CH343G USB TO RS232/485/TTL Interface Converter, Industrial Isolation Waveshare Sku-15817

This is an USB to RS232 / RS485 / TTL Industrial Isolated Converter. It features embedded protection circuits such as power isolation, ADI magnetically isolation, and TVS diode, etc. What’s more, the USB TO RS232 / 485 / TTL comes with an aluminum alloy enclosure, make it solid and durable to work.

The USB TO RS232 / 485 / TTL converter is very easy to use, fully automatic transceiving without delay. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment’s and/or applications with high communication requirement

features:

• Adopt original FT232RNL 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
