B&B Electronics CL214 Current Loop to RS-232 Converter

The B&B Electronics CL214 is a passive current loop to RS-232 serial interface converter designed for connecting legacy current loop devices to modern RS-232 serial ports. It enables reliable communication between 20mA current loop equipment and standard RS-232 serial interfaces without requiring external power.

Key Features:

• Converts 20mA current loop signals to RS-232 serial interface
• Passive design — no external power supply required
• Supports both active and passive current loop configurations
• Compact, inline form factor for easy installation
• Compatible with a wide range of legacy industrial and serial devices
• Rugged construction suited for industrial environments

The CL214 is ideal for integrating older current loop terminals, printers, and industrial equipment into systems that use RS-232 serial communication. Its passive, plug-and-play design simplifies installation and reduces the need for additional power infrastructure.
