B&B Electronics CL201 RS-232 to 20mA Active Current Loop Converter

The B&B Electronics CL201 is an RS-232 to 20mA active current loop interface converter designed for reliable serial data communication in industrial environments. This compact converter bridges the gap between modern RS-232 serial equipment and legacy 20mA current loop devices, making it ideal for connecting terminals, printers, PLCs, and other industrial equipment that use current loop signaling.

Key Features:

• Converts RS-232 signals to 20mA active current loop and vice versa
• Active current loop output — no external power supply required for the loop
• Supports standard RS-232 baud rates for wide compatibility
• Compact, rugged design suited for industrial and commercial applications
• Compatible with a wide range of serial devices including terminals, printers, and PLCs
• Simple inline installation — no software or drivers required
• Built and manufactured in the USA by B&B Electronics

B&B Electronics has been a trusted name in data communications since 1981, specializing in serial, Ethernet, and USB connectivity solutions for industrial and commercial environments. The CL201 reflects their commitment to rugged, reliable, and easy-to-deploy connectivity products.
