 3-Way 2000V Optical Isolation
 Modbus ASCII/RTU Compatible

 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.
