UL Class 1 Division 2
The Ilinx™485DRCI is our premium Industrial
RS-232 to RS-422/485 Converter. Designed for
rugged industrial use, it is UL approved and certified
for operation in Class 1 Division 2 environments.
This DIN rail mountable converter optically
isolates and converts unbalanced, full or half-duplex
RS-232 signals to balanced RS-422/485 signals at
baud rates up to 115.2 Kbps. In addition to optical
isolation, the unit has surge suppression on the RS-
422/485 lines. Featuring Automatic Send Data
Control circuitry, it does not require special software
control of handshake signals in RS-485 mode. The
removable terminal blocks for power and RS-
422/485 signals make wiring easy. It is powered by
a supply voltage of 10 to 48 VDC which is isolated
from all data and signal ground lines. Configuration
is made easy with a 12 position DIP switch on the
bottom of the converter.
Remember, when it comes to reliable
communications in harsh industrial environments,
B&B Electronics’ Ilinx™ brand converters and
isolators are your number one choice.
