USB TO 4CH RS485/422 - 4-channel industrial USB converter - RS485/RS422

Description

4-channel USB-RS485/RS42 converter, created especially for professional industrial applications. It serves as a bridge between the USB interface and the RS485 and RS422 serial standards, ensuring smooth and reliable communication. The converter enables simultaneous and independent data transmission for each of the four channels. Two of them support both RS485 and RS422 protocols, while the other two function as RS485 ports. The module is equipped with built-in protection circuits including a fuse, electrostatic discharge (ESD) protection and a TVS diode, providing additional protection and safety in harsh industrial environments.

The converter ensures lightning-fast data transmission while maintaining stable and reliable operation, and the built-in 120R RS485 output resistors can be easily turned on or off using jumpers, which allows you to adapt the device to specific needs. This makes it an ideal solution for advanced industrial systems, control devices and wherever reliable and fast serial communication is required. Full documentation along with the necessary drivers is available on the product Wiki page.
