InHand Networks SKU: INHUB-Z9480


Industrial RS485 Hub

INHUB-Z9480 is an 8 ports industrial isolation RS485 hub, can extending 8 channels of RS485 slave ports through 1 channel of RS485 master port. It can effectively implement relay, extension and isolation of RS485 network.

features of INHUB-Z9480

Features and Functionality

Three Main Functionality

effectively isolate master and slave ends of RS485 network; meanwhile isolate 8 slave stations.

can effectively extend communication distance of RS485 network.

can implement 1 channel RS485 extending to 8 channels RS485, multiply the numbers of RS485 devices in the network.

main functions: isolation, relay, extension

Opto-Isolation and Power-Isolation

The photoelectric isolation function can effectively make RS485 master and sub devices separate from each other, avoid damage from the ground potential difference of master-slave devices and static, lightning, surge to devices, also can avoid damage from ground loop current caused.

Opto-Isolation and Power-Isolation

High Baud Rate

It is designed for industrial scenarios in harsh environments with a high baud rate up to 460800bps, especially suitable for situations requiring high reliability and safety.

baud rate up to 460800bps

DIN-Rail Installation

DIN-Rail mounting is available for various deployment scenarios.
