ADVANTECH BB-485DRCI

Industrial RS-232 to RS-422/485 Converter 485DRCi PRODUCT FEATURES • Data rates up to 115.2 kbps • Three-way 2,000V optical isolation (input, output, power) • Wide (-40 to +80 °C) operating temperature • UL Class 1/Division 2 ® • Modbus ASCII/RTU, Allen-Bradley DH-485 compatible • 10–48 VDC input power range Model 485DRCi industrial-grade isolated serial converter changes RS-232 ORDERING INFORMATION signals to RS-422 for increased range, or to RS-485 for increased range plus MODEL RS-232 CONNECTOR RS-422/485 CONNECTOR ISOLATION NUMBER multi-drop capability. 485DRCi DB9 Female (DCE) Removable Terminal Block 2,000 V 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 ACCESSORIES optical isolation on input, output, and power lines. In addition to optical isolation, MDR-20-24 - DIN rail mount power supply 24VDC, 1.0 A output power the unit has surge suppression on the RS-422/485 lines. This DIN rail mountable EK-CLIP-MPC - Replacement DIN Rail Clip 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. TBKT1 - Replacement Terminal Block, 2 position 5.08mm Configuration is made via a 12-position DIP switch on the bottom of the converter. 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 Automatic Send Data Control Explained signal ground lines. The 485DRCi may be suitable for use in Modbus and Allen- ® Bradley DH-485 applications. 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 IN THE FIELD and RS-485 serial cards include Automatic Send Data Control. Resolving Electrical Substation Data Glitches Industry: Energy & Natural Resources Utilities Product: Optically Isolated Converter ® Allen-Bradley 1761-NET-AIC ® 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 Technical Support for assistance regarding your specific installation needs.
