Characteristics and performance of RS485 hub (1)

Characteristics and performance of RS485 hub (1)

1. It is designed for industrial automation communication, used for the distance extension and quantity expansion of RS485 communication equipment in complex and harsh industrial field;

2. 1-way RS485 / 232 to 4-way RS485, asynchronous half duplex, two-way communication, data transmission completely transparent;

3. Built in DC-DC power isolation module, isolation voltage 1500V;

4. The optocoupler isolates RS485 master-slave network to ensure data communication is not affected by grounding loop and common mode voltage;

5. TVs transient suppression protection + self recovery fuse current limiting protection;
