MAX490 RS422 to TTL Converter Bidirectional Module interface is two-way communication. This module provides BYZA ports that are super long transmission 1000 meters and ESD 15KV protection.The module has 120-ohm termination resistors, which can effectively reduce the interference of long-range communication. It also includes a TVS diode, the power indicator light, the data receiving and sending indicator light and panoramic view of state data.The TTL side of the module uses 5V DC power supply TXD RXD compatible with a 5V logic signal.It also uses the original imported MAX490 chips, stability and communication speed is far more than domestic products, up to 2.5Mbps.
