Waveshare RS485-HUB-8P Industrial-grade Isolated 8-ch RS485 Hub, Rail-mount Support, Wide Baud Rate Range 1. Interface standard: compliant with RS485 standard 2. Physical interface: RS485 wiring terminal 3. Communication rate: 300-460800bps baud rate (adaptive) 4. Support points: each RS485 interface can support up to 32 nodes 5. Communication distance: 1200m (9600bps), the higher the communication rate, the shorter the distance 6. Working mode: RS485 two-wire (A, B), half-duplex transparent transmission 7. Power supply voltage: DC 9-24V 8. Transmission medium: ordinary parallel wiretwisted pair 9. Size: about 12.1 x 7.2 x 3cm Features: 1. 8-way RS485 slave port can be extended by one 485 master port with isolation and relay 2. RS485 network relay, extension and isolation functions can be realized 3. The isolated RS485 interface at the RS485 master port can be connected to RS485 master control devices, and the extended 8-way isolated RS485 interface can be externally connected to various RS485 slave devices, such as RS485 sensors, etc. 4. Built-in optoelectronic isolation protection circuit, RS485 master and slave devices are isolated, which can effectively protect RS485 master and slave devices from the damage of ground potential difference between devices, static electricity, surge, which can be applied to industrial environment with high requirements of reliability and safety 5. Wide baud rate range, support 300-460800bps wide baud rate communication range (self-adaptive) 6. Support 35mm standard rail with rail clips, easy to install
