RS422 Mutual Transfer TTL Bi-directional Signal Module Full-duplex 422 to SCM MAX490 to TTL

Product description
Description:

- RS422 interface, two-way communication. A B Y Z ultra-long transmission 1000 meters. The module has 15KV ESD protection.
- Add 10 ohm current limiting/overcurrent protection resistor to the board.
- The module comes with TVS diodes. Anti-lightning, anti-spike voltage.
- The module has 120 ohm terminal resistance, it can reduce long-distance communication echo interference effectively.
- With power indicator and data transceiver indicator. Easy to watch the Data status.
- The module TTL side uses 5V DC power supply RXD TXD compatible 5V logic signal.
- The module uses high-quality MAX490 chip, stability and communication speed is extremely high, up to 2.5MBPS.
