B&B Electronics BB2651 RS-232 to RS-485 Serial Converter

The B&B Electronics BB2651 is a compact RS-232 to RS-485 serial interface converter designed for industrial data communication applications. It bridges the gap between RS-232 serial ports and RS-485 multi-drop networks, enabling reliable signal conversion over longer cable runs and in electrically noisy environments.

Key Features:

• Converts RS-232 signals to RS-485 for extended-distance serial communication
• Supports multi-drop RS-485 networks for connecting multiple devices on a single bus
• Designed for industrial environments with robust signal integrity
• Compact form factor suitable for panel mounting or desktop use
• Automatic transmit/receive switching (auto-turnaround) for half-duplex RS-485
• Wide compatibility with standard RS-232 serial ports (DB9)

The BB2651 is well-suited for applications such as PLC communications, building automation, industrial control systems, and data acquisition networks where RS-485 multi-drop wiring is required but the host device only provides an RS-232 interface.
