Black Box IC1650A Async RS-422/485 Repeater, 2 Terminal Block

Black Box IC1650A 2 Terminal Block RS-422 and RS-485 Optical Isolator/Repeater

This compact IC1650A 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.

All data lines, as well as power and ground, are isolated from one side of the unit to the other. The IC1650A uses terminal blocks on each side of the device. It supports Transmit Data A and B, Receive Data A and B, Protective Ground, and Signal Ground. The RS-422 and RS-485 Optical Isolator/ Repeater operates in either 2-wire half-duplex systems or in 4-wire half-duplex or full-duplex systems. By connecting one side of the unit as a 2-wire device and one side as a 4-wire device, equipment meant for a point-to-point RS-422 interface can be connected directly to an RS-485 2-wire multidrop system. You get the speed with the IC1650A, too. It features 12 user-selectable data rates, from 300 bps up to 460.8 kbps.
