B&B Electronics CL227 Current Loop to RS-232 Converter

The B&B Electronics CL227 is a passive current loop to RS-232 signal converter designed for serial data communication applications. It provides a reliable interface between 20mA current loop devices and standard RS-232 serial ports, enabling legacy industrial and serial equipment to communicate with modern computer systems.

Key Features:

• Converts 20mA current loop signals to RS-232 levels
• Passive design requires no external power supply — powered directly from the RS-232 port
• Compact, in-line form factor for easy installation
• Compatible with a wide range of serial devices including terminals, printers, and industrial controllers
• Supports standard RS-232 DB9 or DB25 interface connections
• Rugged construction suitable for industrial environments

The CL227 is ideal for integrating older 20mA current loop serial devices into modern RS-232-based systems without the need for additional power sources or complex wiring. It is a trusted solution from B&B Electronics Manufacturing Company, a well-established manufacturer of serial communication and connectivity products.
