B&B Electronics CL11 RS-232 to 20mA Current Loop Converter

The B&B Electronics CL11 is a compact RS-232 to 20mA current loop converter designed for industrial serial communication applications. It enables reliable data transmission between RS-232 equipment and legacy 20mA current loop devices, which are commonly found in older industrial control systems, terminals, and teletype equipment.

Key Features:

• Converts RS-232 signals to 20mA active or passive current loop
• Supports standard RS-232 serial communication interfaces
• Compact, rugged form factor suited for industrial environments
• No external power supply required for active loop configurations
• Simple in-line installation with no software or drivers needed
• Compatible with a wide range of serial devices and industrial controllers

The CL11 is ideal for engineers and technicians who need to integrate modern RS-232 serial equipment with legacy 20mA current loop systems. Its plug-and-play design makes it easy to deploy without additional configuration, helping to extend the life of existing industrial infrastructure.
