Product in version 2.1

The purpose of this device is to strengthen and separation of telemetry signals using the RS-485 interface. Packets coming at input are regenerated and  sent on 4 separate outputs in identical form, providing fourfold increase in the total length of the bus.
    Distributor is ideal for industrial automation and CCTV systems to get a star topology where damage (short circuit) one of the branch does not lock the transmission in other sectors. Each output has a switchable 120Ohm terminating resistor .

    Galvanic isolation protects the individual branches and equipment connected to them against lightning andtransmission interference caused by the potential difference.

    600W @ 8/20uS surge protection  and short-circuit protection, provide high resistance to damage in cooperating devices in the event of a surge, lightning and vandalism..
