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

3.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)

4.Using half-hole process design, thickness 0.8mm, class easy to use as a master, but also welding terminal use.

5.With RXD, TXD signal indicator, send and receive situation panoramic view.
