Designed for rugged industrial use, the 485DRCi is UL approved and certified
for operation in Class 1/Division 2 environments and also offers 2,000V 3-way
optical isolation on input, output, and power lines. In addition to optical isolation,
the unit has surge suppression on the RS-422/485 lines. 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.
Configuration is made via a 12-position DIP switch on the bottom of the converter.
ACCESSORIES
MDR-20-24 - DIN rail mount power supply 24VDC, 1.0 A output power
EK-CLIP-MPC - Replacement DIN Rail Clip
TBKT1 - Replacement Terminal Block, 2 position 5.08mm
TBKT2 - Replacement Terminal Block, 5 position 5.08mm
31D1-28100 - Null Modem Adapter (Allen-Bradley® applications)
Featuring Automatic Send Data Control circuitry, the converter does not require
special software control of handshake signals in RS-485 mode. 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. The 485DRCi may be suitable for use in Modbus and Allen-
Bradley® DH-485 applications.
Automatic Send Data Control Explained
As operating systems become more complex, it is increasingly difficult to control
an RS-485 driver with standard software and the RTS line. This is especially true
in Windows and multi-tasking operating systems. With B+B SmartWorx’ Automatic
Send Data Control circuit, driver control is in the converter hardware, so you do not
have to work with software at all.
The circuit monitors data flow and enables the driver during transmission and
automatically disables it when no data is being sent. There is no need to rework
software or install new drivers. Most B+B SmartWorx RS-232 to RS-485 converters
and RS-485 serial cards include Automatic Send Data Control.

The 485DRCi can be used as a replacement for the Allen-Bradley® Advanced
Interface Converter (AIC+) in some applications. The 31D1-28100 null modem
adapter accessory is required for these applications. Contact B+B SmartWorx
