Industrial Grade Isolated RS485 HUB 8-Channel – Rail-Mount Support
This RS485 8-Channel HUB uses the 1-channel RS485 master port to expand 8-channel RS485 slave ports. It supports isolation, extension, and relay functions of the RS485 network.
It has been designed to support rail-mount. You can use it for different applications such as intelligent instrument monitoring, security and safety IoT, IoT gateway, and data acquisition.
Primary Function
RS485 Network Relay, Isolation, and Extension.
Connection Diagram
You can connect the RS485 Host device to the Isolated RS485 Master Port. Connect multiple RS485 slave devices such as sensors, to the extended 8-channel isolated RS485 port.
Normally, a hand-in-hand connection is required for the RS485. If a master station or the star connection is needed, this 8-Channel RS485 HUB can isolate the connection interface between multiple RS485.
Industrial Isolation Protection
A photoelectric isolation protection circuit on this device isolates the RS485 master and slave devices. It eliminates the risk of damage due to the ground potential difference between devices. It also has anti-electrostatic, anti-surge, and lightningproof protection.
Wide Baud Rate Range
Self-adaptive wide baud rate communication range: 300bps to 460800bps
Rail-Mount Support
Compatible with the 35mm standard guide rail. Easy-to-install rail-mount buckle.
