USB to RS232 / RS485 / TTL Industrial Isolated Converter

Features USB to RS232 / RS485 / TTL converter

• USB to RS232, USB TO RS485, USB TO TTL (UART)
• Contains an original FT232RL, fast communication, stable and reliable, better compatibility!
• Integrated unibody power isolation, provides stable isolated voltage, does not need additional power supply for the isolated terminal
• We-board unibody magnetic isolation, enables signal isolation, high reliability, strong anti-interference, low power consumption
• We-board of TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient surge voltage in the circuit, lightning resistant and anti-electrostatic
• Onboard resettable fuse and protection diodes, provides current/voltage stable outputs, provides overcurrent/overvoltage resistance, improves shock resistance
• Fully automatic transceiver circuit without delay, makes the USB port communicate quickly and stably with different interfaces, without interfering with each other
• We-board TTL serial 3.3V/5V voltage translator, configure the TTL level via switch
• Aluminum alloy housing with anodic oxidation, CNC process opening, solid and durable
• 3 LEDs to indicate power and transceiver status
• High-quality USB-B and RS232 connectors, smooth plug/pull
