Model BB-485OPDRI-PH is our premium heavy industrial RS-422/485 isolated repeater. Designed for rugged industrial environments, it has been put through some of the most exacting compliance tests in the industry. Meeting the requirements of IEC 61850-3 and IEEE 1613, it is suitable for installation in electrical substations. These specifications are more stringent than the NEMA TS1/TS2 requirements for transportation applications. Powerful isolation on both data ports protects your equipment and data from damaging ground loops and surges. Additional isolation on the power supply circuits adds a third degree of protection.

Packaged in a rugged IP30 metal case, it extends full or half-duplex RS- 422/485 signals an additional 4000 feet and allows you to add another 32 nodes to your network. Our bit-wise enabled circuitry automatically detects the data rate without setting a DIP switch.
