LM YN TTL to RS485 Module Industrial Grade RS485 to TTL with Isolated Single Chip Serial Port UART

LM YN TTL To RS485 Module User Manual Download Link: https://www.amazon.com/clouddrive/share/VeJxArJNKUxUu9P2y9q8ne1MPEGKgHjnMsqgQNlPgBR Description: 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 with a wide voltage input 3.0V-5.5V, 3.3V system and 5.0V system to achieve a perfect compatibility, 3.3V or 5.0V communication signals can match. Module Features: 1. This module fully considered the 485 bus lightning protection design and anti-jamming design, the use of isolated chips, to achieve the power and signal isolation, with isolation and bus protection, high EMC, EMI performance. In the field long distance transmission, connect the ground, can play a good anti-interference and lightning around, making the 485 bus more secure. Indoor short distance transmission does not require ground wire. 2. The use of standard 2.54 spacing design, user-friendly secondary development. 3. With 120 ohm matching resistor, short-circuit RO that match the resistance, long-distance transmission recommended short circuit. 4. Support multi-machine communication, the same network can connect at least 128 nodes. 5. Can be hot-swappable, there will not be signal death phenomenon. Parameter: Wide voltage input: 3.0V-5.5V; 3.3V and 5.0V signal are all compatible. Power and signal completely isolated, isolation voltage to DC2500V; Industrial design, anti-interference ability, while the use of 485 lightning design, industrial and field conditions can be used in harsh conditions. Working temperature: -40 ? ~ +85 ?; Transmission distance: recommended within eight hundred meters to use, more than 800 meters plus repeaters. Using half hole industrial design, control board thickness 0.8mm. With RXD, TXD signal indicator. Package Included: 1*TTL To RS485 Module
