About EC Buying 10 Pcs TTL To RS485 XY-017 Level
Description: 3.3V and 5.0V power supply are perfectly compatible 3.3V and 5.0V signals are perfectly compatible Industrial-grade design, with strong anti-interference ability, and more effective 485 lightning protection design, can be used in industrial sites and harsh outdoor environment, with operating temperature of - 40 ℃ to+85 ℃, and transmission distance of up to kilometers (test with 850 meters of 2 * 1.5 cable, it is recommended to use within 800 meters, more than 800 meters, please add repeaters) The half-hole process design is adopted, and the plate thickness is 0.8mm, which can be easily used as a sub-motherboard, and can also be used for welding terminals With RXD and TXD signal indicators, have a panoramic view of the reception and reception conditions Baud rate: 110~128000bps perfect support Features: This module fully considers the 485 bus lightning protection design and anti-interference design. When the field long-distance transmission, the "grounding" end of the module is connected to the ground, which can play a good role in anti-interference and lightning protection, making the 485 bus safer; Indoor short-distance transmission may not be connected to the ground Adopt standard 2.54 spacing design to facilitate your secondary development It has 120 Ω matching resistance, which can be enabled by short circuit R0. Short circuit is recommended for long-distance transmission Support multi-computer communication and allow to connect to the bus of 128 devices at most This module can be hot swapped, and there will be no signal blocking phenomenon of other 485 chips hot swapped Large-area copper laying to prevent signal interference
