RS422 interface, two-way communication. B Y Z A ultra far transmission 1000 meters. The module has ESD 15KV protection. Onboard to increase the limit of 10 ohms current limiting current protection. Module with TVS diode. Anti lightning, peak voltage. The module has 120-ohm termination resistors, which can effectively reduce the interference of long-range communication. Have the power indicator light and the data receiving and sending indicator light. Panoramic view of state data.Module TTL side using 5V DC power supply TXD RXD compatible with 5V logic signal.
The module uses the original imported MAX490 chips, stability, and communication speed is far more than domestic products, up to 2.5MBPS.
Module size: 5.0cm x 2.7cm
