The W&T 86201 is an industrial interface converter designed for bidirectional communication between RS232 devices and RS422/RS485 equipment. It converts one data channel and one handshake channel in each direction while providing galvanic isolation between the interfaces and power supply. Its DIN-rail housing, flexible RS485 operating modes, and industrial noise immunity make it suitable for reliable serial communication in demanding automation environments.
