This USB to 4-port RS485 converter is an industrial-grade non-isolated converter with strong electrostatic protection. It incorporates the CH344L processor chip and SP485EEN serial driver chip, providing enhanced stability and compatibility.
It features built-in voltage/lightining protection, a resettable fuse, ESD, and TVS protection circuits, all enclosed in an aluminum alloy casing. This converter is suitable for various industrial control equipment and applications with demanding communication requirements.

Extending USB to 4-port RS485, allows concurrent and independent communication for each port.
Onboard TVS (Transient Voltage Suppressor), effectively protects against voltage surges, transient voltage spikes and electrostatic voltages.
Onboard resettable fuse and protection diodes, ensures stable current/voltage levels, provides over-current/over-voltage protection.
Onboard RS485 output terminal 120R resistors, enabled/disabled via DIP switch.
Aluminium alloy, solid and durable, well-crafted.
