B&B Electronics CL23 Current Loop to RS-232 Converter

The B&B Electronics CL23 is a current loop to RS-232 interface converter designed to bridge legacy 20mA current loop serial devices with modern RS-232 equipment. This compact, passive conversion solution is ideal for industrial and commercial environments where older current loop peripherals — such as terminals, printers, and PLCs — need to communicate with RS-232 ports on computers and controllers.

Key Features:

• Converts 20mA current loop signals to RS-232 voltage levels
• Supports both active and passive current loop configurations
• Compact, inline form factor for easy installation
• No external power required for passive loop operation
• Rugged construction suited for industrial environments
• Compatible with standard DB-25 and DB-9 serial interfaces (with appropriate cabling)

The CL23 from B&B Electronics Manufacturing Company provides a reliable, plug-and-play solution for integrating current loop serial devices into RS-232 environments without the need for complex wiring or additional software drivers.
