The ILinx™485DRCI-PH is our premium Heavy Industrial
RS-232 to RS-422/485 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.
Remember, when it comes to reliable communications in
harsh industrial environments, B&B Electronics’ ILinx™ brand
converters and isolators are your number one choice.
