Tags: RS422 to TTL Converter Module, Serial Converter, SP3490 IC
The RS422 interface is used for differential and bidirectional serial data communication. Its main advantage over RS485 is the ability to transmit data over long distances. Two pins, A and B, serve as the transmitter, while Y and Z act as the receiver, and they are used in a differential configuration to ensure reliable communication.The RS422 to TTL Converter Module is equipped with a TVS protection diode and a 10 Ω input resistor to control incoming current. The main IC of this Converter Module is the SP3490 IC, which ensures stable and efficient signal conversion.This makes the RS422 to TTL Bidirectional Converter Module an ideal choice for applications requiring reliable two-way communication between differential serial devices.
