The ILinx™ 485DRCI-PH is our premium Heavy Industrial RS-232 to RS422/485 Isolated Converter. 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 converts unbalanced, full or
half-duplex RS-232 signals to balanced RS-422/485 signals. Featuring
Automatic Send Data Control circuitry, it does not require special software
control of handshake signals in RS-485 mode. Our bit-wise enabled
circuitry automatically detects the data rate without setting a DIP switch.
