Overview

2 and 3-way isolated optical repeater converts, protects & extends data signals

Optical isolation protects your devices from transient surges and ground loops on your data line. The optical repeaters/isolators add 4,000 feet (1.2 km) and another 32 nodes to an RS-485 data circuit. By configuring one side as RS-422 and the other as RS-485, the models can act as a converter to allow your four wire RS-422 equipment to talk to a 2-wire RS-485 device.

View and compare our optical isolation solutions below. See the Details, Specs, and Download tabs for further information on each optical repeater.
