- Wide voltage supply (3.0V~30V), limit voltage 33V, recommended to use within 30V, the minimum voltage should be higher than 2.8V.
- Compatible with 3.3V and 5.0V signals, both can match the module.
- Excellent EMC and EMI performance.
- Strong anti-jamming ability, and strong 485 lightning protection design, working temperature is – 40 C to + 85 C.
- With terminal and silicone wire, it is very convenient to use.
- With RXD and TXD signal indicators.
- This module fully considers the lightning protection design and anti-interference design of 485 bus. It has very high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance. When long-distance transmission in the field, connecting the “earth” end of the module to the earth can play a very good anti-interference and anti-lightning role, making 485 bus safer; indoor short-distance transmission can not access the earth.
- With standard 2.54 spacing needle arrangement, it is convenient for your secondary development.
- With 120 Euro matching resistance, short R0 can make matching resistance possible, and short R0 is recommended for long-distance transmission.
- Supporting multi-machine communication, the same network can connect at least 40 nodes.
- Hot plugging can be done without signal blocking.
- Anti-interference routing and copper laying to prevent interference of signals.
