B&B Electronics CL245 Current Loop to RS-232 Converter

The B&B Electronics CL245 is a passive current loop to RS-232 converter designed for connecting current loop serial devices to standard RS-232 ports. It provides a simple, reliable interface between 20mA current loop equipment and RS-232 host systems without requiring external power, making it ideal for industrial and legacy serial communication applications.

Key Features:

• Converts 20mA current loop signals to RS-232 logic levels
• Passive design — powered directly from the RS-232 port, no external power supply required
• Supports full-duplex communication
• Compact form factor for easy inline installation
• Compatible with a wide range of current loop serial devices including terminals, printers, and industrial equipment
• Rugged construction suited for industrial environments

The CL245 is an effective solution for integrating older current loop serial equipment with modern RS-232 host computers and controllers, preserving legacy hardware investments while maintaining reliable data communication.
