B&B Electronics CL07 RS-232 to Current Loop Converter Interface Adapter

The B&B Electronics CL07 is a passive RS-232 to 20mA current loop converter designed for connecting RS-232 serial devices to equipment using current loop interfaces. This compact interface adapter is widely used in industrial environments where legacy serial communication equipment requires current loop signal compatibility.

Key Features:

• Converts RS-232 signals to 20mA current loop for serial device interfacing
• Passive design — draws power directly from RS-232 signal lines, no external power supply required
• Supports full-duplex communication for reliable two-way data transmission
• Compact, robust form factor suitable for industrial and commercial environments
• Compatible with a wide range of RS-232 serial devices including terminals, printers, and PLCs
• Simple plug-and-play installation with no software or drivers required

The CL07 is an ideal solution for integrating older current loop peripherals with modern RS-232 serial ports, extending the useful life of legacy industrial equipment. Manufactured by B&B Electronics Manufacturing Company (now Advantech B+B SmartWorx), a trusted name in serial communications and industrial networking solutions.
