3.3V 5V TTL UART to RS485 Isolated Interface Converter Module Single-chip Serial Port UART Industrial

Description

• 3.3V 5V TTL UART To RS485 Isolated Interface Converter Module Single-chip Serial Port UART Industrial

Module description:

This product through a high-end isolation chip to achieve TTL, RS485 on both sides of the power and signal perfect isolation, anti-interference ability. The power supply is a wide voltage input (3.0V-5.5V), which enables perfect compatibility between 3.3v system and 5.0V system. 3.3V or 5.0v communication signals can be matched.

This transparent transmission module realized TTL signal and RS485 signal mutual transfer, but we must know, 485

This communication mode can realize two-way communication, but cannot be carried out in both directions at the same time. It must be carried out alternately, that is to say, each end of the communication channel can be the sending end or the receiving end, but at the same time, information can only have one transmission direction.

Realize the automatic flow control of RS485 signal and automatic switch of sending and receiving direction. Using this module is as simple as your operation of serial port.

Baud rate :100-256000bps perfect support

Module highlights:

1, wide voltage supply (3.0V-5.5V)

2. 3.3v and 5.0V signals are perfectly compatible and can be matched with the module

3, power and signal completely isolated, high and EMlI performance, isolation voltage up to 2500vDc4, industrial design, strong anti-interference ability, while using a more powerful 485 lightning protection design, can be used in the industrial site and wild harsh environment, the working temperature of -40 to +85, Transmission distance up to kilometers (with 850 meters of 2*1.5 cable test, it is recommended to use within 800 meters, more than 80o meters please add a repeater)

5, adopt half hole process design, board thickness 0.8mm, can be easily used as the word mother board, can also be used for welding terminals

6, with RXD, TXD signal indicator light, sending and receiving state panoramic view
