Descrição de 2X TTL to RS485 Adapter 485 Serial Port UART Level Converter Module 3.3V 5V

Single chip microcomputer ,TTL turn RS485 module, 485 turn UART serial port, Level transfers, Hardware automatic flow control
Only one in the whole network, 3.3V and 5.0V power supply, RS485 signal perfectly compatible with automatic flow control module.
Has RXD, TXD signal indicator light, monitor send and receive status
Using the standard 2.54 pitch design, easy secondary development.
Colour:

Material:metal
Operating Temperature: -40 Degrees Celsius ~ + 85 Degrees Celsius.
Size:42.8mm x 15.22mm x 0.8mm.
Absolute adopts imported chip, industrial design, strong anti-interference ability, at the same more effective -protection design, 485 can be used in industrial field and field under the harsh environment. (Using 850 meters with 2 x 1.5 cable to do the test, it is recommended to be used within the 800 meters, more than 800 m, please add extra repeaters).
Use half hole process design, thickness of 0.8 mm, can be used easily as a child motherboard, also can be used welding terminals.
With 120 European match resistance, can make short sub R0 can match resistance, proposed the short answer the long distance transport.
Support multiple machine communications, allowed to take in to 128 devices the bus.
This module can be hot plug, there will be no other 485 chip hotplug phenomenon of signal to death.
Large area laying copper, preventing signal interference.
