Single Chip Microcomputer TTL Turn RS485 Module Automatic Flow Control
This module fully considered 4855 Bus Lightning protection design Anti interference Design When the long-distance transmission in the field, the "Earth" of the module is connected to the earth, which can play a very good role in anti interference and lightning protection. 485 Bus is more secure; indoor short distance transmission can not access the earth. with a standard 2..54 Spacing design to facilitate your two development
Have 120Ou matching resistance, short connect R0Can match the resistance, long distance transmission is recommended.
Support multi machine communication, allowing access to the most 128A device on the bus
This module can be hot plug, no other 485Chip hot swap signal plug phenomenon
Large area laying copper, preventing signal interference
Module highlights:
(1) 3.3V and 5.0V power perfect compatibility
(2) 3.3V and 5.0V signal perfect compatibility
(3) the absolute adopts imported chip, industrial design, strong anti-interference ability, at the same time, adopt more effective lightning protection design, 485 can be used in industrial field and field under the harsh environment, the working temperature of 40 to + 85 , the transmission distance of km (with 850 m 2 * 1.5 cable testing, suggest use within 800 meters, more than 800 meters please add repeater)
(4) the half hole process design, plate thickness 0.8mm, can be easily as composite plate, can also be used for welding terminal
(5) has the RXD, TXD signal indicator lights, send and receive status panoramic view
