Model BB-485DRCi industrial-grade isolated serial converter changes RS-232
signals to RS-422 for increased range, or to RS-485 for increased range plus
multi-drop capability.
Designed for rugged industrial use, the BB-485DRCi is UL approved and
certified for operation in Class 1/Division 2 environments and 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.
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. An external power supply is required (not included, sold
separately).
The BB-485DRCi may be suitable for use in Modbus and Allen-Bradley® DH-485
applications.
