The
HUB-485-8 is a rugged, industrial-grade, optically-isolated, 8-Port RS485 Hub / Splitter, which can be used to expand RS-485 networks by splitting one RS-485 network into eight (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 / Splitter operates within a temperature range of -40ºF to 185ºF (-40ºC to 85ºC), features 600W surge protection, 15kV ESD static protection and 2500V opto-isolation circuitry, which effectively protect your RS485 devices from ground loops, noise problems, transient surges, remote lightning and spikes. The unit was designed in such a way that data coming from the input (RS485) will transmit to all eight 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. Also, the failure of any individual loop will not affect other loops, making the RS485 networks more robust and reliable. This 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.
