B&B Electronics CL272 Current Loop to RS-232 Converter

The B&B Electronics CL272 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 converter enables reliable serial communication between industrial equipment, terminals, printers, and data acquisition systems that use differing interface standards.

Key Features:

• Converts 20mA active/passive current loop signals to RS-232 and vice versa
• Supports both active and passive current loop configurations
• No external power required for active loop operation
• Compact form factor for easy in-line installation
• Compatible with a wide range of legacy industrial serial devices
• Rugged construction suitable for industrial environments

The CL272 is an ideal solution for facilities maintaining legacy current loop equipment alongside modern RS-232 systems, eliminating the need for costly hardware replacement. Simply connect the converter in-line to achieve transparent, reliable data communication across both interface standards.
