RSV automatic flow direction control module compatible with 3.3V and 5.0V power supply and signal
No need to “receive-transmit” control, use this module is as simple as operating the serial portFeatures:
- Transmission distance up to kilometers.
- Absolute adopts imported chip, industrial design, strong anti-interference ability, at the same time more effective lightning protection design, 485 can be used in industrial field and field under the harsh environment. （Using 850 meters with 2 * 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, the thickness of 0.8 mm, can be used easily as a child motherboard, also can be used welding terminals.
- With a standard 2.54 spacing design, convenient your secondary development.
- 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 a hot plug, there will be no other 485 chip hotplug phenomenon of a signal switch to death.
- Large area laying copper, preventing signal interference.
- Wide power supply range: 3.3V~5.5V
- 3.3V and 5.0V signal compatibility
- It adopts originally imported chip, industrial grade design, strong anti-interference ability, and adopts more effective 485 lightning protection design. It can be used in industrial and harsh environments, working temperature is -40 ° C to +85 ° C The transmission distance can reach up to a kilometer (using 850 meters of 2*1.5 cable for testing, it is recommended to use within 800 meters, more than 800 meters, please add repeater)
- Semi-hole process design, thickness 0.8mm, easy to use as a motherboard or solder terminal
- With RXD, TXD signal indicator, the receiving and receiving status is in full view
