B&B Electronics CL283 RS-232 to Current Loop Converter

The B&B Electronics CL283 is an RS-232 to Current Loop interface converter designed for reliable serial data communication between RS-232 devices and current loop (20mA) equipment. Current loop interfaces are commonly used in industrial environments, legacy serial terminals, printers, and automation systems where long-distance, noise-immune data transmission is required.

Key Features:

• Converts RS-232 serial signals to 20mA current loop and back
• Supports full-duplex (active/passive) current loop operation
• Compact DIN-rail or panel-mount compatible form factor
• Designed for industrial and legacy serial integration applications
• Wide compatibility with RS-232 host devices including PCs, PLCs, and terminals
• Rugged construction suitable for demanding industrial environments

The CL283 from B&B Electronics (now known as Advantech B+B SmartWorx) provides a straightforward solution for integrating older current loop peripherals into modern RS-232 serial environments, extending the useful life of legacy equipment without costly system overhauls.
