Opto-Isolated RS485 Hub / Splitter (Industrial)

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 (1) RS-485 network into four (4) - 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 RS232 / RS485 devices from ground loops, noise problems, transient surges, remote lightning and spikes. The unit comes with options for RS485 or RS232 input, for easy installation. 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 d
