The I-7510 provides 2-way optical isolation between one piece of RS-422/RS-485 equipment and the rest of the system. It can also be used as a repeater to extend the transmission signal of an existing RS-485 network to beyond 4000 feet. Additionally, an RS-485 system can be expanded beyond the 256 node limitation imposed by the standard. It can also be used to convert a 4-wire RS-422 signal to a 2-wire RS-485 signal, and vice versa.

We use I-7510 for extending our RS-485 communication distance. I've been using these for many years and like the wide operating temperature range.
