Features:

1. This product through a high-end isolation chip to achieve the TTL, RS485 on both sides of the power and signal perfect isolation, anti-interference ability super. Power is a wide voltage input (3V ~ 5.5V), to achieve the 3.3v system and 5V system is perfectly compatible;

2. 3.3v or 5V communication signals can match;

3. Wide voltage supply (3.0V ~ 5.5V);

4. 3.3V and 5V signal perfectly compatible, can match the module;

5. Power and signal completely isolated, high EMC and EMI performance, isolation voltage up to 2500VDC;

6. Industrial design, anti-interference ability, while the use of more powerful 485 lightning design, industrial and field can be used in harsh environments, the working temperature of -40 ℃ ~ 85 ℃. Transmission distance of up to kilometers (with 850 meters of 2 * 1.5 cable to do the test, it is recommended to use within 800 meters, more than 800 meters plus repeaters);

7. Using half-hole process design, thickness 0.8mm, class easy to use as a master, but also welding terminal use with RXD, TXD signal indicator, send and receive situation panoramic view support multi-machine communication, the same network can connect at least 128 nodes can be hot-swappable, there will be no signal to death phenomenon.
