USB to RS485/RS422 Converter

$ 18.78 Price excluding tax

Compact USB to RS485/RS422 Converter that enables a computer or USB-equipped host to communicate with industrial and serial devices using RS-485 or RS-422 interfaces. Ideal for industrial automation, control systems, instrumentation, and serial communication applications.

Description

The USB to RS485/RS422 Converter provides a convenient bridge between a modern computer’s USB port and equipment using balanced RS-485 or RS-422 serial communication.

The converter supports RS-485 2-wire half-duplex communication as well as RS-422 4-wire full-duplex communication, allowing it to interface with a broad range of industrial controllers, PLCs, meters, sensors, automation equipment, and other serial devices.

The USB connection allows the converter to appear to the host computer as a serial/COM interface through the appropriate driver, making it useful for applications that require communication with legacy or industrial serial equipment without a native RS-485/RS-422 port.

Many implementations are powered directly from USB and feature automatic transmit/receive direction control, eliminating the need for an additional power supply or manual switching during normal RS-485 operation.
