B&B Electronics CL208 Current Loop to RS-232 Converter

The B&B Electronics CL208 is a current loop to RS-232 serial converter designed for reliable signal conversion between 20mA current loop devices and standard RS-232 serial equipment. This passive interface module allows legacy current loop peripherals — such as teletypes, terminals, and industrial instruments — to communicate seamlessly with modern RS-232 serial ports.

Key Features:

• Converts 20mA active/passive current loop signals to RS-232 serial interface
• Supports both active and passive current loop configurations
• No external power required for active loop operation
• Compact, rugged housing suitable for industrial environments
• Easy inline installation — no software or drivers required
• Compatible with a wide range of RS-232 serial hosts and current loop devices

The CL208 is an ideal solution for integrating older current loop equipment into modern serial communication systems, making it a cost-effective alternative to replacing legacy hardware. Manufactured by B&B Electronics Manufacturing Company, a trusted name in industrial serial communication and data interface products.
