Description

Isolated 2-Channel RS485 Hub

Expands 2-channel RS485 ports via a 1-channel master RS485 port with isolation and relay transmission

RS485-HUB-2P, front view RS485-HUB-2P, features

Features

RS485-HUB-2P is an industrial-grade isolated RS485 hub that can expand 2-channel RS485 sub-ports via a 1-channel master RS485 port. It implements RS485 network relay transmission, expansion, and isolation functions, featuring a screw terminal for power input. The DIN-rail mount design ensures easy installation and cost-effectiveness. Suitable for applications in data collection, IoT gateways, safety and IoT security systems, as well as smart device monitoring.
