B&B Electronics CL224 Current Loop to RS-232 Converter

The B&B Electronics CL224 is a current loop to RS-232 converter designed for industrial serial communications applications. It provides reliable signal conversion between 20mA current loop interfaces and standard RS-232 serial ports, enabling legacy current loop devices to communicate with modern RS-232 equipment.

Key Features:

• Converts 20mA current loop signals to RS-232 serial communication
• Supports both active and passive current loop configurations
• Compact, rugged housing suitable for industrial environments
• No external power required for active loop operation
• Simple inline installation with no software configuration needed
• Compatible with a wide range of serial devices, terminals, and industrial controllers

The CL224 is an ideal solution for integrating older current loop peripherals — such as printers, terminals, and industrial sensors — into modern RS-232 serial networks. Its passive design and straightforward connectivity make it a dependable choice for factory floors, control rooms, and data communication installations.
