B&B Electronics CL213 Current Loop to RS-232 Converter

The B&B Electronics CL213 is a compact current loop to RS-232 serial interface converter designed for industrial data communication applications. It enables legacy 20mA current loop serial devices to communicate with modern RS-232 equipped systems, making it ideal for integrating older industrial equipment, terminals, and instrumentation into contemporary serial networks.

Key Features:

• Converts 20mA current loop signals to RS-232 serial interface
• Supports both active and passive current loop configurations
• Compact, rugged housing suited for industrial environments
• No external power required in active mode — powered from the current loop itself
• Simple plug-and-play installation with no software configuration required
• Compatible with a wide range of industrial terminals, PLCs, and instrumentation

The CL213 is a reliable solution for facilities that need to extend the life of current loop serial equipment or bridge communication between legacy and modern systems without costly hardware replacement.
