B&B Electronics CL06 Current Loop to RS-232 Converter

The B&B Electronics CL06 is a passive current loop converter designed to interface RS-232 serial devices with 20mA current loop equipment. This compact, cost-effective solution enables reliable communication between legacy current loop systems and modern RS-232 ports without requiring an external power supply.

Key Features:

• Converts RS-232 signals to and from 20mA current loop
• Passive design — draws power directly from the RS-232 port, no external power required
• Compact inline form factor for easy installation
• Supports full-duplex serial communication
• Compatible with a wide range of RS-232 host devices and serial terminals
• Ideal for connecting legacy industrial current loop peripherals to modern systems

The CL06 is well suited for industrial automation, data acquisition, and legacy system integration applications where current loop communication remains in use. Its passive, plug-and-play design makes installation straightforward with no additional configuration required.
