Industrial USB TO 8CH TTL UART CONVERTER
Stable Transmission | Multi Devices | Multi Systems

Features At A Glance
- Extending USB to 8CH TTL (UART) with hardware flow control, allows concurrent and independent communication for each channel
- Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, improve shock proof performance
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection
- Onboard voltage translator circuit, with surge suppress and ESD protection, safe and stable communication
- Onboard TTL serial port 3.3V and 5V voltage level switch, allows selecting TTL level
- Aluminium alloy enclosure with oxidation dull-polish surface, CNC process opening, solid and durable, well-crafted
- 4 LEDs for indicating the power and transceiver status
