Key item features
- 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.
- The standard 2.54 spacing design, convenient for your secondary development. with 120 euro matching resistance, short connection can enable matching resistance, long distance transmission recommended short connection. Support multi-machine communication, the same network can be connected to at least 128 nodes. Can be hot swap, not appear the phenomenon of signal plug.anti-interference type wiring and copper paving mode, to prevent signal interference.
- 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. This module fully considers the 485 bus protection design and anti-interference design
- The use of isolation chip, realize the isolation of power and signal, with isolation and bus protection functions extremely high EMC(electromagnetic compatibility), (electromagnetic anti-interference) performance, in of foreign distance transmission, the "ground" end of the module into the earth, It can play a very good role of anti-interference and -protection, so that the 485 bus is , indoor short distance transmission can not access the earth.

Product details
Baud rate:100-256000bps perfect support
Module :
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 EMC and EMlI performance, isolation voltage up to 2500vDc
4. industrial design, strong anti-interference ability, while using a more powerful 485 -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 2x1.5 cable test, it is recommended to use within 800 meters, more than 800 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
Due to different product batches, the appearance , which does not affect the use
