Industrial Grade Isolated RS485 HUB 8-Channel – Rail-Mount Support
This 8-Channel RS485 HUB utilises a single-channel RS485 master port for the expansion of eight RS485 slave ports.
Offering features like isolation, extension, and relay functions, it enhances the capabilities of RS485 networks.
Specifically designed for rail-mounting, it serves various applications including intelligent instrument monitoring, security and safety IoT, IoT gateway usage, and data acquisition.
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.
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.
