Supports RS485 Network Relay, Extension And Isolation Functions
The Isolated RS485 Master Port Can Be Connected To The RS485 Host Device, And The Extended 8-Ch Isolated RS485 Port Can Be Connected To Various RS485 Slave 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.
Built-in photoelectric isolation protection circuit, can effectively isolate RS485 master and slave devices to avoid the damage of ground potential difference between devices, 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.

The HUB-485-4 is a rugged, industrial-grade, optically-isolated RS485 Hub / Splitter / Repeater, which can be used to expand RS-485 networks by splitting one RS-485 network into four (star wiring), in turn increasing the maximum number of nodes and the distance covered by an RS-485 network. This industrial opto-isolated RS485 Hub operates within a temperature range of -40ºF to 185ºF (-40ºC to 85ºC), and it features 600W surge protection, 15kV ESD static protection and 2500V opto-isolation circuitry, which effectively protect your RS232 / RS485 devices from ground loops, noise problems, transient surges, remote lightning and spikes. It was designed so that data coming from the input (RS232 or RS485) will transmit to all four loops of RS-485 networks. However, each loop of RS485 devices will transmit data back to the input only, thus reducing any possible interference between each loop of the RS485 devices, making the RS485 networks more robust and reliable.
The RS485 Hub supports standard RS485 devices as well as BACnet and Modbus devices, and it supports data rates up to 115.2K Baud and features data format auto-sensing and self-adjusting. Therefore, it requires no manual settings, software drivers or flow control, making the unit a highly reliable and truly plug-and-play device.
A separate external power supply is included in the package, and, thanks to the professional and unique casing design, the product can be mounted directly on a wall, panel or DIN Rail, without a need of using any unsecured DIN-Rail or wall-mount brackets.
