Isolated 2-way RS485 hub repeater

One RS485 master port can be expanded to two RS485 slave ports with isolation and relay


Product Features

The RS485-HUB-2P is an industrial-grade, isolated RS485 hub that expands one RS485 master port into two RS485 slave ports. It provides RS485 network relay, expansion, and isolation functions. It features terminal block power access and a DIN-rail enclosure for easy installation and a high cost-effectiveness. It is suitable for data acquisition, IoT gateways, IoT security, and smart instrument monitoring.
