Expands 4-ch RS485 ports via 1-ch RS485 master port, with isolation and relay

RS485-HUB-4P is an industrial grade isolated RS485 hub that can expand 4-ch RS485 sub ports through 1-ch RS485 master port. It can realize signal relay, extension and isolation functions of RS485 network, with screw terminal for power input. Rail-mount case design, easy to install, and cost-effective. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring...

The isolated RS485 master port can be connected to the RS485 host device, and the extended 4-ch isolated RS485 port can be connected to various RS485 sub devices, such as RS485 sensors, etc.

Generally the RS485 requires a hand-in-hand connection, if a star connection (master station as the center) is required, this RS485 hub can effectively isolate the connection interference between multiple RS485 devices.

Built-in optoelectronic isolation circuit, can effectively isolate RS485 master and sub devices, provides multiple protections such as anti-electrostatic, lightningproof & anti-surge, which is suitable for the industrial environment with high reliability and safety requirements.

Supports 300~460800bps Wide Baud Rate Communication Range (self-adaptive)

Supports 35mm standard guide rail, with rail-mount buckle, easy to install
