TTL Signal System Conversion Module RS422 Full Duplex Bidirectional Switch RS 422 To TTL Module SCM MAX490

Module Description:

1. RS422 interface, bidirectional communication. A B Y Z ultra long transmission 1000 meters

2. The module has 15KV ESD protection.

3. Add a 10 ohm current limiting protection resistor on the board.

4. The module is equipped with TVS diodes. Anti lightning strike, anti peak voltage.

5. The module has a 120 ohm terminal resistor, which can effectively reduce long-distance communication echo interference.

6. There are power indicator lights and data transmission and reception indicator lights. The data status is fully visible.

7. The TTL module uses a 5V DC power supply, while the RXD TXD is compatible with 5V logic signals.

8. The module adopts the original imported MAX490 chip, which has much higher stability and communication speed than domestic products, reaching up to 2.5MBPS

9. Module size: 5.0cm * 2.7cm
