B&B Electronics CL202 Current Loop to RS-232 Converter

The B&B Electronics CL202 is a passive current loop to RS-232 signal converter designed for reliable serial data communication between current loop devices and standard RS-232 equipment. It provides a simple, cost-effective interface solution for connecting legacy 20mA current loop peripherals—such as printers, terminals, and industrial controllers—to modern RS-232 serial ports.

Key Features:

• Converts 20mA current loop signals to RS-232 voltage levels
• Passive design requires no external power supply
• Compatible with standard DB-25 or DB-9 serial interfaces
• Supports full-duplex operation for simultaneous send and receive
• Rugged construction suited for industrial environments
• Compact form factor for easy installation in tight spaces

The CL202 is ideal for industrial automation, manufacturing, and legacy system integration where 20mA current loop devices must communicate with RS-232-equipped computers or controllers. Its passive, plug-and-play design minimizes installation complexity and eliminates the need for additional power sources.
