BB-485DRCI RS-232 to RS-422/485 Converter - 3-way Isolation

Published on : Tuesday 30-11--0001

Model 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 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.

Features:

• Data rates up to 115.2 kbps
• Three-way 2,000V optical isolation (input, output, power)
• Wide operating temperature
• UL Class 1/Division 2
• Modbus ASCII/RTU compatible
• 10–48 VDC input power range

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.

It is used in Electrical, Process Industries And Rugged Industrial Environment.
