Industrial Grade TTL to RS485 Module RS485 Signal Converter 3V 5.5V Isolated Single Chip Serial Port UART Module

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, 3.3v or 5V communication signals can match. Wide voltage supply (3.0v ~ 5.5v) 3.3v and 5V signal perfectly compatible, can match the module Power and signal completely isolated, high EMC and EMI performance, isolation voltage up to 2500VDC 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) 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
