B&B Electronics CL276 Current Loop Converter RS-232 to 20mA

The B&B Electronics CL276 is a current loop interface converter designed to bridge RS-232 serial communications with 20mA current loop devices. This type of converter is commonly used in industrial environments to connect modern RS-232 serial ports to legacy equipment, PLCs, sensors, and instrumentation that operate on a 20mA current loop interface.

Key Features:

• Converts RS-232 serial signals to 20mA current loop format
• Supports passive current loop operation
• Compact form factor suitable for panel or desktop mounting
• Industrial-grade construction for reliable operation in demanding environments
• Plug-and-play interface — no special drivers required
• Compatible with a wide range of serial communications equipment

The CL276 is an ideal solution for facilities that need to maintain connectivity between modern computers or controllers and older current loop-based peripherals such as printers, terminals, and process control equipment.
