This gateway module is an industrial USB-RS232/485/TTL isolated converter designed for industrial use, containing the original FT232RL chip. It has built-in protection circuits, such as power isolation, ADI magnetic isolation, TVS diode and more. In addition, the USB-RS232/485/TTL converter is equipped with an aluminum alloy shell, making it robust and durable.

USB TO RS232/485/TTL is extremely easy to use, a fully automatic transceiver without delay. Thanks to fast data transmission, stability, reliability and safety, it is an ideal choice for industrial control equipment and applications with demanding data communication requirements.

Features

• USB TO RS232, USB TO RS485, USB TO TTL (UART)
• Uses the original FT232RL, fast data transmission, stable and reliable, better compatibility
• Built-in unibody power isolation, provides a stable isolated voltage, no extra power supply needed for the isolated connector
• Built-in unibody magnetic isolation, enables signal isolation, high reliability, strong anti-interference, low power consumption
• Built-in TVS (Transient Voltage Suppressor), effectively attenuates overvoltage and transient spike voltages in the circuit, lightning-resistant and anti-static
• Built-in self-resetting fuse and protection diodes, ensures stable current/voltage output, provides over-current/over-voltage protection, improves shock resistance
• Fully automatic transceiver circuit without delay ensures the USB port communicates with different interfaces quickly and stably without mutual interference
• Built-in TTL serial 3.3 V/5 V voltage converter, TTL level configured by switch
• Aluminum alloy shell with sandblasting and anodized oxidation, openings processed by CNC, sturdy and durable
• 3 LED indicators to show power and transceiver status
• High-quality USB-B and RS232 connectors, smooth connecting/disconnecting
