Absolute adopts chip, industrial design, strong anti-interference ability, at the same time 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 up to 128 devices on the bus.
This module can be hot plug, there be no other 485 chip hotplug phenomenon of signal switch to death.
Large area laying copper, preventing signal interference.
