Description
Features: 1. Wide voltage power supply (3.0V ~ 30V), the limit voltage of 33V, it is recommended to use within 30V, the minimum voltage is higher than 2.8V. 2. Has a very high EMC and EMI performance. 3. Compatible with 3.3V and 5.0V signals, can match the module. 4. With RXD, TXD signal indicator, send and receive situation panoramic view. 5.With a standard 2.54 pitch pin, to facilitate your secondary development; With a terminal block and silicone wire, the use of very convenient. 6. With 120 ohm matching resistance, shorted R0 can be enabled to match the resistance, recommended shorted for long-distance transmission. 7. Support multi-machine communication, the same network can connect at least 40 nodes. 8. Can be hot- swappable, there will be no signal to death phenomenon. 9. Using anti-jamming alignment and copper to prevent signal interference. Package Included: 1x TTL to RS485 Signal Converter Module 1x 2.54 White Socket with 4P Lines
Features:
- Operating voltage range: DC 3.0V ~ 30V; Baud rate: 110 ~ 256000bps; Operating temperature range: -40 C to +85 C.
- Compatible with 3.3V and 5.0V signals; TXD & RXD Indicator: the TTL to RS485 Adapter is designed with Transmit Data indicator light and Receive Data indicator light, convenient for your monitoring.
- The 485 bus is with lightning protection and anti-jamming function, with high EMC, EMI performance. When using for long-distance transmission in the field, the module EARTH side please connect to the ground, can achieve well anti-interference and lightning protection function; for indoor short-distance transmission, it cannot connect to ground.
- Transmission Distance up to kilometers : with 850 meters of 2*1.5 cable to do the test, it is recommended to use within 800 meters, more than 800 meters plus repeaters.
