RS422 Mutual Conversion TTL two-way Signal module full duplex MAX490 to TTL module

Module description:

1 RS422 interface, two-way communication. B Y Z A ultra far transmission 1000 meters

The 2 module has ESD 15KV protection.

3 onboard to increase the limit of 10 ohms current limiting current protection.

4 module with TVS diode. Anti lightning, peak voltage.

The 5 module has 120-ohm termination resistors, which can effectively reduce the interference of long-range communication.

6 have the power indicator light and the data receiving and sending indicator light. Panoramic view of state data.

7 module TTL side using 5V DC power supply TXD RXD compatible with 5V logic signal.

8 module uses the original imported MAX490 chips, stability and communication speed is far more than domestic products, up to 2.5MBPS.

9 module size: 5.0cm*2.7cm
