TTL To RS485 Converter 3.3V/5.0V Hardware Automatic Control Converter Module For Arduino For Arduino AVR

P roduct Descrtion

The power supply of this product is wide voltage (3.0V~30V), 3.3V system and 5.0V system compatible, 3.3V and 5.0V signals can match. This product with a terminal block and silicone wire, direct wiring use, all ed ch, powerful, protection design, anti-interference ability, industrial, quality aurance 1 year!

This transmiion module to achieve the TTL signal and RS485 signal interchange, but we must know, 485 is half duplex communication, this communication can achieve two-way communication, but not in both directions at the same time, must Alternately; that is, each section of the communication channel can be either a transmitting end or a receiving end, but at the same time, the information can have only one transmiion direction.

To achieve the RS485 signal automatic flow control, send and receive direction automatically switch, use this module with your operation as simple as the serial port .

Baud rate: 110 ~ 256000bps

P roduct Parameter

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. compatible with 3.3V and 5.0V signals, can match the module.

3. has a very high EMC and EMI performance.

4. the use of ed chs, industrial design, anti-interference ability, while the use of powerful 485 design, industrial and field can be used in harsh environments, the working temperature of -40 ° to +85 °, transmiion 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).

5. with a terminal block and silicone wire, the use of very convenient.

6. with RXD, TXD signal indicator, send and receive situation panoramic view.

7. factory direct, to ensure technical support and services, but also OEM and ODM.

P roduct F eatures

1. This module fully considered the 485 bus protection design and anti-jamming design, high EMC, EMI performance, long-distance transmiion in the field, the module "acce to the earth" side acce to the earth, can play well The anti-interference and protection of the role of the 485 bus more secure; indoor short-distance transmiion can not acce the earth.

2. with a standard 2.54 pitch pin, to facilitate your secry development.

3. with 120 ohm matching resistance, shorted R0 can be enabled to match the resistance, long-distance transmiion recommended shorted.

4. support multi-hine communication, the same network can connect at least 40 nodes.

5. can be hot-swappable, there will be no signal to death phenomenon.

6.anti-jamming alignment and copper way to prevent interference with the signal.
