B&B Electronics CL246 Current Loop to RS-232 Converter

The B&B Electronics CL246 is a passive current loop to RS-232 level converter designed for industrial serial communication applications. It enables seamless interfacing between legacy 20mA current loop devices and modern RS-232 serial equipment, making it an essential tool for data acquisition systems, industrial controllers, and telecommunications equipment.

Key Features:

• Converts 20mA current loop signals to RS-232 voltage levels
• Passive design — draws power from the RS-232 host port, no external power supply required
• Compact, inline form factor for easy installation
• Supports full-duplex communication
• Compatible with standard RS-232 serial ports and DB-25 or DB-9 interfaces
• Rugged construction suited for industrial environments

The CL246 is ideal for connecting older teletype, industrial terminal, or process control equipment that uses current loop serial interfaces to contemporary RS-232 hosts, PLCs, or computers. B&B Electronics Manufacturing Company has long been a trusted name in serial communications and industrial networking solutions.
