RS232 to Terminal Serial Port DB9 Adapter Previous 
The TTL To RS485 Converter Module provides TTL signal to RS485 signal interchange for serial communication applications. It supports two-way communication in half-duplex operation and offers automatic send and receive direction switching. The module uses a wide voltage power supply and supports 3.3V and 5.0V signals. It is designed for industrial use with strong anti-interference performance, lightning protection design, and long-distance transmission support. Terminal block wiring and silicone wire connections make direct wiring convenient. RXD and TXD indicators show transmission and reception status.
