In-line Isolators and Repeaters


RS-422/485 Optically Isolated Repeater

Protects and extends with one device

Optically isolates and protects devices, plus it extends the range of RS-422 and 485 data lines an extra 4,000 feet.

The versatile terminal blocks even let you join 2-wire RS-485 with RS-422 without the need for another converter..

It’s like two devices in one.
