Industrial USB to 8-Channel TTL Converter

This USB to 8-channel converter is a versatile USB to UART adapter designed to extend USB connectivity to 8 independent TTL channels. Each channel operates with hardware flow control, providing simultaneous and reliable communication. This converter has multi-protection circuits, including self-recovery fuses and protection diodes, providing stable current and voltage outputs. It protects against over-current and over-voltage conditions, improving shockproof performance. Additionally, the built-in TVS (Transient Voltage Suppressor) effectively mitigates surge voltage and transient spikes, offering comprehensive lightning and ESD protection. It also has a voltage translator circuit with surge suppression and ESD protection, providing safe and stable communication. It supports multiple systems including Mac, Linux, Android, Windows 11, 10, 8.1, 8 and 7, making it an ideal choice for industrial projects requiring reliable and secure data transmission. Features

* Extending USB to 8CH TTL (UART) with hardware flow control, allows concurrent and independent communication for each channel

* Self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, improve shockproof performance

* TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning proof & ESD protection

* Voltage translator circuit, with surge suppress and ESD protection, safe and stable communication

* TTL serial port 3.3V and 5V voltage level switch, allows selecting TTL level

* Aluminium alloy case with oxidation dull-polish surface, CNC process opening, solid and durable

* 4 LEDs for indicating the power and transceiver status
