B&B Electronics CL274 Current Loop to RS-232 Converter

The B&B Electronics CL274 is a passive current loop to RS-232 signal converter designed for connecting RS-232 serial devices to 20mA current loop systems. This compact interface converter enables communication between modern RS-232 equipment and legacy current loop peripherals such as older terminals, printers, and industrial controllers.

Key Features:

• Converts between RS-232 and 20mA current loop signal levels
• Passive design — no external power supply required for current loop operation
• Supports both active and passive current loop configurations
• Compatible with standard RS-232 DTE and DCE devices
• Compact, rugged housing suitable for industrial environments
• Simple plug-and-play installation with no software or drivers required

The CL274 is an ideal solution for maintaining and integrating legacy current loop equipment into modern RS-232 serial communication networks, making it a valuable tool for industrial automation, data acquisition, and system integration applications.
