B&B Electronics CL35 20mA Current Loop to RS-232 Converter

The B&B Electronics CL35 is a 20mA current loop to RS-232 serial interface converter designed for industrial and legacy serial communication applications. It enables reliable data communication between current loop devices — such as older terminals, printers, and industrial equipment — and modern RS-232 serial ports.

Key Features:

• Converts 20mA current loop signals to standard RS-232 voltage levels
• Supports passive and active current loop configurations
• Compact, rugged enclosure suitable for industrial environments
• No external power required in active mode configurations
• Simple, plug-and-play installation with no software drivers needed
• Compatible with a wide range of legacy serial devices and host systems

The CL35 is an ideal solution for integrating older 20mA current loop peripherals into contemporary serial communication infrastructures, making it a trusted choice for industrial automation, data acquisition, and legacy system maintenance.
