B&B Electronics CL286 RS-232 to Current Loop Converter

The B&B Electronics CL286 is a RS-232 to Current Loop interface converter designed to bridge communication between RS-232 serial devices and 20mA current loop equipment. This passive converter enables reliable serial data transmission over longer distances than standard RS-232 allows, making it ideal for industrial automation, legacy system integration, and process control environments.

Key Features:

• Converts RS-232 signals to 20mA active/passive current loop
• Supports full-duplex communication
• Compact, DIN-rail or panel-mountable form factor
• No external power required for passive current loop operation
• Rugged design suited for industrial environments
• Compatible with a wide range of RS-232 host devices

The CL286 is a trusted solution for connecting modern RS-232 host systems to older teletype-style (TTY) current loop peripherals such as printers, terminals, and PLCs. Its straightforward wiring and passive operation make installation simple and maintenance-free.
