Description
Isolated 2-ch RS485 Hub
Expands 2-ch RS485 Ports Via 1-ch Master RS485 Port With Isolation And Relay Transmission
Features
The RS485-HUB-2P is an industrial-grade isolated RS485 hub, which can expand 2-ch RS485 sub-ports via 1-ch master RS485 port. It achieves RS485 network relay transmission, expansion, and isolation functions, with screw terminal for power input. The DIN rail mount design makes it easy to install and cost-effective. Suitable for applications like data collection, IoT gateways, safety & security IoT systems, and smart instrument monitoring.
