TTL to RS485 Converter XY-K485 TTL-to RS485 Serial Port Converter Module Automatic Flow Direction Control Adapter Board for Arduino AVR
About this item
- This transparent transmission module realizes the mutual conversion between the TTL signal and the RS485 signal, but you should know that the 485 is a half-duplex communication. With this method of communication, two-way communication can be realized, but it cannot be carried out simultaneously in two directions. They must alternate alternately
- Realizes automatic control of RS485 signal flow and automatically switches the transmission and reception direction
- Industrial grade design, strong anti-interference ability and powerful 485 flash protection design can be used in industrial sites and harsh outdoor environments. The operating temperature is -40℃ to +85℃ and the transmission distance should be less than 800m. More than 800m, please add repeater
- Wide voltage power supply (3.0V~30V), the limit voltage is 33V, it is recommended to use within 30V, and the minimum voltage must be higher than 2.8V, 3.3V and 5.0V signals can match.
- It has extremely high EMC and EMI performance. With terminal blocks and silicone wires, it is very convenient to use. With RXD and TXD signal indicators, you get a panoramic view of the transmission and reception status
