Black Box IC1650A - Optical Isolator Reptr RS422 an

Quick Facts
This compact device links RS-422 4-wire and RS-485 2-wire systems while using optical isolation to protect equipment and lines from damaging ground loops.

The BLACK BOX® RS-422 and RS-485 Optical Isolator/Repeater enables you to connect equipment meant for a point-to-point RS-422 4-wire interface to an RS-485 2-wire multidrop system.

It can be used to optically isolate one piece of RS-485 equipment from the rest of an RS-485 system or one local group of RS-485 equipment from another or it can be used as a repeater to expand an existing RS-485 system beyond the standard's 32-node limitation.
