USB - RS485 (B) industrial converter CH343G from Waveshare + USB extension cable

The industrial USB to RS485 converter is a reliable solution for bi-directional signal conversion between USB and RS485. It provides stable and fast data transmission rates from 300bps to 3Mbps, making it the ideal choice for demanding industrial applications. Built-in protections such as TVS, ESD protection, and a resettable fuse guarantee safe and reliable operation of the device, even in harsh environments. With a transmission distance of up to 1.2km and support for up to 32 nodes, this converter is ideal for systems with multiple devices. Features at a glance:

* Supports bi-directional USB to RS485 conversion

* Fast communication, stable and reliable, improved compatibility

* Built-in TVS (Transient Voltage Suppressor), effectively suppresses overvoltage and voltage spikes in the circuit, lightning and electrostatic protection

* Built-in reset fuse and protection diodes ensure stable current/voltage outputs, provide current/voltage overload protection, improve shock resistance

* 3 LEDs to indicate power and transmission status
